Radiance Data Assimilation for the Weather Research and Forecasting (WRF) Model: Overview and Results

The Weather Research and Forecasting (WRF) model and its variational assimilation system (WRF-Var) are widely used by both the research community and some operational centers. A general satellite radiance assimilation framework has been developed in the WRF-Var system over the past three years. The WRF-Var radiance assimilation capability was designed to meet the requirements of both basic research and operational applications,and will be available to the research community along with the community WRF system. Radiance assimilation capabilities in the WRF-Var - the fast radiative transfer model, bias correction algorithm, quality control, and observation error tuning - will be described. Both the RTTOV and CRTM radiaitve transfer systems are incorporated into the WRF-Var system. Case study results on assimilating AMSU-A observations to improve Katrina track and intensity analysies and forecasts will be presented. Extended experiments over different regions to assess radiance assimilation impact yield encouraging results. Preliminary findings on cloud/rain affected radiance assimilation using CRTM will also be shown. The presentation will conclude with a demonstration of radiance assimilation with the WRF- 4DVAR system.

High frequency radar and mapping coastal currents

This seminar will give participants an in-depth look at High Frequency Radar (HFR) - a technology for measuring ocean surface current velocities (speed and direction) and surface waves in near real time. This information can be used during search and rescue operations to track the probable path of victims and drifting ships. HFR data can also be used to support oil spill response, harmful algal bloom monitoring, and assessment of coastal water quality. The information can additionally provide value in ecosystem assessment and fisheries management, when evaluated retrospectively. Unlike many other techniques, HFR is unaffected by weather conditions such as clouds, fog or precipitation. Because its signal hugs the oceans surface, and is conducted by it, HFR can observe the ocean at distances far beyond the line-of-sight (distances often exceed 200 km). Also, this surface-hugging mode makes the placement of HFRs more flexible, in that they can be located almost anywhere along the shoreline. By combining data from two HFRs, a two-dimensional map of surface currents can be produced, spanning thousands of square kilometers. Currently, about 100 HFRs are operating on US coastlines. Nearly all are owned by research universities working in partnership with NOAA IOOS. NOAAs current HFR efforts are led by the IOOS Program in partnerships with NOS/CO-OPS and NWS/NDBC. This technology was developed in the 1970s and 1980s in a NOAA Research laboratory in Boulder, Colorado and was referred to as Coastal Ocean Dynamics Applications Radar (CODAR). After that development, a commercial company was spun off that markets the HFRs under the name CODAR Ocean Sensors SeaSondes�. More than 90 percent of the HFRs in the US are of the CODAR type. The seminar will give an HFR overview including details on the national HFR data server and management system, regional capabilities and future plans.

Progress and plans for NOAA Integrated Ocean Observing System (IOOS) program

As "our eyes on the oceans, coasts, and Great Lakes", the Integrated Ocean Observing System (IOOS) is a tool for tracking, predicting, managing, and adapting to changes in our marine environment. IOOS delivers the data and information needed to increase our understanding of our waters, so decision makers can take action to improve safety, enhance the economy, and protect the environment. NOAA is proud to lead a national partnership of 17 federal agencies and 11 regions working together to link marine data in an easy-to-use standard format that will provide users with a composite picture of our nation's waters in an accurate and timely manner. This seminar will discuss some of the complexities of the national IOOS efforts, what NOAA and its partners are doing to integrate our ocean and coastal data, and IOOS benefits to data users, the general public, and the nation.

Seminar title: Naked gobies (Gobiosoma bosc) as Indicators of Oyster Reef Restoration Success
Speaker: Terra Lederhouse (Fisheries Affairs Division, Office of International Affairs)
The native oyster population in the Chesapeake Bay is estimated to be <1% of its historic level. Overfishing, pollution, habitat degradation, and disease have diminished the population and the important ecosystem services it once provided. Extensive restoration efforts by federal, state, and non-profit organizations have attempted to restore these services, including habitat for other bay species. To develop a useful indicator of oyster reef restoration success, naked gobies were collected from experimental oyster reefs of various densities in two Chesapeake Bay tributaries from 2005-2007. Naked goby abundance, biomass, and total body lipid content were compared between treatments to determine the habitat value of restored reefs to this resident fish species. Results indicate that restoration efforts should aim to produce adult oyster densities >100 m-2 to provide suitable ecological benefit to naked gobies. [Download PDF]

Seminar title: Microbial Carbon and Nitrogen Cycling in Euphotic Estuarine Sediments: A Case Study from Chesapeake Bay
Speaker: Frank M. Parker (Office of the Assistant Administrator, Oceanic and Atmospheric Research)
Understanding fundamental relationships with respect to carbon (C) and nitrogen (N) flows in estuarine sediments is critical if we are going to mitigate the effects of eutrophication caused by increased N loading to coastal systems. Given the shallow nature of estuaries, a large fraction of the benthos may lie within the photic zone (e.g., ~ 21 % of the Chesapeake Bay is < 2 m deep) and account for as much as half of total estuarine primary production. Here I present results from seasonal dual stable isotopic tracer (DI13C and 15NH4+) experiments that quantify benthic microbial production (e.g., bacteria and benthic microalgae) in terms of C and N, partition that production between water column and porewater nutrient sources in the light and dark, and trace the fate of that production into secondary consumers. Results show that euphotic sediment microbes are an important link in estuarine benthic-pelagic coupling, benthic microalgae play a critical role in the euphotic sediment microbial loop, and benthic bacteria are the dominant microbial pool for C and N immobilization into biomass.

Seminar 1: Denitrification Contributes to Nitrogen Loss in Fertilized Arctic Tundra Sites
Speaker: Marselle Alexander-Ozinskas
Abstract: About 30% of the global soil carbon pool is stored in northern latitudes (40-70°N), which have experienced larger temperature increases due to atmospheric warming than equatorial regions over the past few decades. Soil temperature increases affect carbon and nitrogen cycling and could alter net ecosystem carbon balance. To examine the future of arctic soil carbon pools following climate-driven changes, the potential for denitrification, nitrification, and mineralization were measured in several ecosystems surrounding the Toolik Lake Long-Term Ecological Research station near Toolik Lake, Alaska, after manipulation to simulate the effects of climate warming. Results indicate that denitrification may contribute to large, observed net nitrogen losses in these systems, suggesting a pathway of potential soil carbon loss following the effects of climate warming [Download Power Point slides]

Seminar 2: Back from the Beach: A Quantitative Analysis of Beachfront Values and Tax Base
Speaker: Ed Gorecki
Abstract: The devastation caused by Hurricanes Katrina and Rita resulted in record losses of life and property, and elevated concerns for coastal protection to their highest levels. In addition to rising sea levels over the last several decades, increases in extreme weather events in the Gulf of Mexico have led to substantial beach erosion along the Gulf coast. In 2007 the Nueces County Commissioners Court adopted a 350-foot building set-back along the North Padre Island, TX, coastline. Prior to its implementation, landowners and developers claimed substantial financial losses as a result of this land development restriction. This lecture reviews the economic implications of coastal and environmental protection along the Gulf of Mexico, particularly along the Coast of Nueces County, to determine the significance of this effect on property values, and the potential loss of revenue to the community and local tax base.

Seminar 1: Using GPS collars to monitor the activity and habitat use of Canada lynx in Minnesota
Speaker: Julie Palakovich Carr (Office of Senator Maria Cantwell)

Abstract: Since direct observation of free-ranging animals is difficult, remote methods for monitoring animal behavior have been developed. Recent advances in GPS collars allow for both the location and activity of an animal to be recorded internally in the collar. Although several studies have validated the activity counter portion of GPS collars for large herbivores, this has not been done to date on a small carnivore. Methods to relate animal activity level and habitat use were developed by observing a captive Canada lynx wearing a GPS collar. These methods were then applied to data collected from seven free-ranging lynx in northeastern Minnesota. Differences in habitat selection when lynx were active or inactive were analyzed. Additionally, I will be highlighting my research on the effects of maternal characteristics on Atlantic cod recruitment and the effects of a restored oyster reef on water quality. [Download PDF]

Seminar 2: The Decay of Particulate Organic Matter in the Ocean …and of Bills in the U.S. Senate
Speaker: Lynn Abramson (Office of Senator Barbara Boxer)

Abstract: What do the biological carbon pump and the legislative process have in common? Both concern some form of progression or transport: the biological carbon pump involves the movement of particulate organic matter through the water column, whereas the legislative process involves the movement of bills through Congress. A predictive understanding of either of these processes requires investigation of the source, alteration, and exchange of “material” during transit. In this seminar, Lynn Abramson will draw parallels between her dissertation work on the marine carbon cycle and fellowship work in Senator Barbara Boxer’s office, discussing her perspective on some of the strategies and obstacles involved in affecting science-based policy decisions. [Download PDF]

Seminar 3: Regional adaptation in feeding preference for chemically-rich seaweeds by the marine herbivore, Ampithoe longimana
Speaker: Amanda McCarty (Legislative Fellow, Senate Commerce, Science and Transportation Committee, Subcommittee on Oceans, Atmosphere, Fisheries and the Coast Guard)

Abstract: Field and laboratory manipulations and molecular analysis were used to better understand the ecology and evolution of marine seaweed-herbivore interactions. This work focused specifically on comparisons between populations of the amphipod Ampithoe longimana from cold-temperate New England, warm-temperate North Carolina, and subtropical Florida. Populations from throughout this distribution are exposed to locally distinct seaweed communities, exhibit regional variation in tolerance for a chemically-defended seaweed, and have limited gene flow between regions. Therefore, A. longimana serves as a unique example of a locally adapted marine organism. [Download PDF]

Data Assimilation Experiments Using Quality Controlled AIRS Version 5 Temperature Soundings

The AIRS Science Team Version 5 retrieval algorithm has been finalized and is now operational at the Goddard DAAC in the processing (and reprocessing) of all AIRS data. The AIRS Science Team Version 5 retrieval algorithm contains a number of significant improvements over Version 4. Of particular significance is the new methodology to generate accurate case-by- case, level-by-level, error estimates for the atmospheric temperature profile, as well as for channel-by-channel clear column radiances Ri. These error estimates are used for quality control of the retrieved products. We have conducted forecast impact experiments assimilating AIRS quality controlled temperature profiles using the NASA GEOS-5 data assimilation system, consisting of the NCEP GSI analysis coupled with the NASA FVGCM, run at a spatial resolution of 0.5° latitude x 0.5° longitude. Assimilation of quality controlled temperature profiles resulted in significantly improved forecast skill compared to that obtained from analyses when all data used operationally by NCEP, except for AIRS data, is assimilated, on the one hand, and also compared to forecasts obtained when AIRS radiances are assimilated in place of AIRS Quality Controlled Temperature profiles. A description of the AIRS Version 5 retrieval methodology will be given, as well as the data assimilation experiments conducted and their results.

Corals/Marine Protected Areas: Fifth in a Series of Panel Presentations given by NOAA Knauss Sea Grant Fellows (see details below).

Seminar 1: Fine scale genetic population structure in the threatened Acropora palmata and Acropora cervicornis in Southwest Puerto Rico
Speaker: Joselyd Garcia (Marine Mammal Commission)
Abstract: During the 1980s and 1990s, populations of Acropora palmata and Acropora cervicornis experienced region-wide declines of up to 95% or more in some areas due mostly to disease. Once considered the most important reef builders in the Caribbean, their rapid decline prompted their listing as threatened under the Endangered Species Act in 2006. To understand the genetic connectivity between reefs in southwestern Puerto Rico, sequences of the mitochondrial control region were recovered from geographically adjacent and distant populations of A. palmata and A. cervicornis. Results suggest that there is fine scale population structure and recovery of these reefs might rely on the survival and sexual reproduction of local populations rather than replenishment from distant reefs. In this presentation, I will also discuss my current project and the experiences gained through the U.S. Marine Mammal Commission.

Seminar 2: Do closed fishing areas in New England qualify as marine protected areas?
Speaker: Christine Patrick (Ocean Exploration and Research Program)
Abstract: Marine protected areas (MPAs) are often presented as a new addition to the “traditional toolkit” of fisheries management measures used by the U.S. federal government. However, temporary or rotational closed areas have been used in New England since before the creation of the federal exclusive economic zone (EEZ) and the expanded federal power to manage fisheries. Despite this fact, the MPA canon does not acknowledge New England closed fishing areas as MPAs, or even as the theoretical ancestors of MPAs. Is this exclusion justified? What are the differences between New England closed fishing areas and MPAs?

Data Assimilation Experiments Using Quality Controlled AIRS Version 5 Temperature Soundings

GeoSTAR represents a new measurement concept that now makes a geosynchronous microwave sounder possible. A small proof-of- concept prototype has been developed at JPL under NASA's Instrument Incubator Program that has demonstrated that the aperture synthesis approach used in GeoSTAR is feasible and will meet all relevant measurement requirements. The full-size space version will have essentially the same performance in GEO as the AMSU system currently achieves in LEO but has the added benefit of the time-continuous observations that are possible from GEO, and complete soundings will be produced every 15-20 minutes over most of the Earth disc. Applications range from numerical weather prediction to climate monitoring, but GeoSTAR is particularly relevant to hurricanes and severe storms and will provide key measures of convective activity, continuously and in real time. GeoSTAR is the baseline payload for the "PATH" mission, one of 15 NASA missions recommended by the NRC in its recent "Decadal Survey". NOAA also has a compelling interest in a GEO microwave sounder, and there is a strong possibility for a joint NASA-NOAA GOES-R/S Mission-of-Opportunity in the 2015-2018 time frame.

Non-Gaussian Data Assimilation Methodologies

In the current versions of both variational and ensemble data assimilation a very important assumption is made about how the errors are distributed. This assumption is that the errors are normally (Gaussian) distributed, Lorenc (1986). This assumption is implicitly using the fact that the difference between to normal random variables is also a normal random variable. Therefore, if this is true then the model variables and the observations have to be normal random variable as well. However, this can not be applied to positive definite variables. There are several variables involved with cloud dynamics which are not normally distributed (Miles et al. 2000). There are also observations which are not normally distributed (Stephens et al. 2002, Sengupta et al. 2004, Donofrio 2007). The very important random variables, used in all the scales in atmospheric modeling from synoptic to cloud resolving, are those associated with moisture. In Dee and Da Silva (2003) the choice of moisture variable is investigated and one such approach to deal with the constraint of non-negativity is to take the natural logarithm of the specific humidity. The effect of taking the logarithm is to make the transformed variable be able to go negative. This technique is implicitly using the fact that the logarithm of a lognormal variable is a normal variable. As shown in Fletcher and Zupanski (2007), the statistic that the transform method finds in the original lognormal space is a median of the multivariate lognormal distribution. An alternative method has been developed for a mixture of lognormal and normal random variables (Fletcher and Zupanski, 2006a, b, 2007, Fletcher, 2008). This method is based upon seeking the mode of the underlying analysis probability density function, pdf, (Lorenc 1986). This new approach finds the only statistic of the multivariate lognormal distribution that is unique and bounded with respect to the variance. In the next section we briefly summarize the development of the hybrid lognormal-normal assimilation equations for the 3D case. In Section 3 we outline the derivation of a functional, least squares type approach for the 4D case for lognormal observations. In Section 4 we present to different probability model approaches so that the expression is independent on any assumptions from any probability distributions. In Section 5 we present some results from an experiment where we compare the hybrid approach with the transform approach in the Lorenz'63 model. In Section 6 we present some thoughts on the implications and the application of the work presented here. We finish we some conclusions and plans for further work.
