Regional Data in Partnership with the San Francisco Exploratorium
Geography and Environment
currents, SLP, buoys, salinity, satellites, winds, ...
As a tool to support NOAA's new partnership with the renowned science museum, the Exploratorium, and in collaboration with the Central and Northern California Ocean Observing System and other regional data providers, NOAA has developed a Web page to make it easy to visualize near-real time data in San Francisco Bay. The interface uses Google Maps and the latest AJAX technology to combine and compare data from diverse sources. Users are able to visualize water temperature, salinity, and other station-based measurements along with overlays of satellite measurements of Sea Surface Temperature (SST) and radar measurements of currents. Users are also able to compare time series of measurements from various stations and sources.

Twentieth Century Reanalysis Project (Version 2)
Geography and Environment
CIN, MSL, volcano, soil temperature, humidity, ...
The Twentieth Century Reanalysis Project is an effort led by PSD and the University of Colorado CIRES Climate Diagnostics Center to produce a reanalysis dataset for the entire twentieth century, using only surface observations of synoptic pressure, monthly sea surface temperature and sea ice distribution. The observations have been collected with the support of the Atmospheric Circulation Reconstructions over the Earth initiative, and working groups of GCOS and WCRP. The Project uses a recently-developed Ensemble Filter data assimilation method which directly yields each six-hourly analysis as the most likely state of the global atmosphere, and also estimates uncertainty in that analysis. This dataset will provide the first estimates of global tropospheric and stratospheric variability spanning 1871 to present at six-hourly resolution (V2). In Version 2, data files are also produced for daily and monthly values of the variables. The first version has global coverage spanning 1908-1958, and two degree longitude-latitude horizontal resolution (V1).

Coastwatch
Geography and Environment
Carbon Dioxide, currents, roughness, Terra, OSCAR, ...
NOAA CoastWatch was established in 1987 in response to two significant environmental events. A Harmful Algal Bloom (HAB) event occurred off the coast of North Carolina transporting the toxic Gymnodinium breve cells from Florida via the Gulf Stream into the colder coastal waters near Cape Lookout. Also, a severe mammal die-off occurred, where more than 700 bottlenose dolphins died off the mid-Atlantic coast. Both instances prompted Federal and State officials to explore additional data sources for monitoring the coastal waters, such as near real-time satellite data. CoastWatch has expanded from POES/AVHRR SST data for the East Coast to providing a variety of environmental data (i.e. SST, ocean color, winds, etc.) from several different satellite platforms covering all U.S. coastal waters, including Hawaii and Alaska. Today, sea surface temperature maps support meteorological weather predictions and also support commercial and recreational activities (e.g., fishing). Biologists utilize ocean color radiometry data and derived chlorophyll-a and total suspended matter/turbidity products to identify runoff plumes and blooms and also predict HABs; and sailors and commercial shipping pilots use ocean surface vector winds for safe navigation.

Reanalysis Intercomparison and Observations
Geography and Environment
CIN, MSL, ERA, longwave, volcano, radiation flux, ...
Reanalysis is a scientific method to combine observations and models for developing a comprehensive record of how weather and climate are changing over time. A reanalysis dataset typically extends over several decades or longer, and covers the entire globe from the Earth's surface to well above the stratosphere. Reanalysis products are used extensively in climate research and services, including for monitoring and comparing current climate conditions with those of the past, identifying the causes of climate variations and change, and preparing climate predictions. Recently, the National Oceanic and Atmospheric Administration (NOAA), National Aeronautical and Space Administration (NASA), European Centre for Medium-Range Weather Forecasts (ECMWF), and Japanese Meterological Agency (JMA) have produced new reanalysis datasets that, in total, span 1871 to present. It is crucial to our scientific understanding of climate variability and change that these new datasets be validated and compared with each other and with the underlying observations. International working groups of the Global Climate Observing System (GCOS, the climate element of the Global Earth Observing System of Systems) and the World Climate Research Program, and the Atmospheric Circulation Reconstruction over the Earth (ACRE) initiative need a community portal to exchange quickly and disseminate publicly results of such intercomparisons. NOAA's own mission and strategic goals regarding reanalyzes, as well as its leading role in the US Global Change Research Program, GCOS, WCRP, and ACRE, make NOAA the logical and obvious choice to serve a website dedicated to improving understanding of the international reanalysis datasets, including those recently generated by NOAA, the 20th Century Reanalysis and Climate Forecast System Reanalysis. The new website "reanalyses.org" will serve as a central portal for Reanalysis Intercomparison and Observations (RIO) by NOAA, NASA, ECMWF, JMA, and national and international scientists. The website should be outside the "noaa.gov" domain. It will help NOAA and the international scientific community to improve the climate science and services that reanalyzes underpin. NOAA strategic plans and US Global Climate Research Program plans to which NOAA Office of Atmospheric Research and the new NOAA Climate Service will respond specifically call for advances in understanding reanalysis datasets. The RIO will coordinate with the NOAA Climate Services portal to make the intercomparison and observation documentation public.
