Enjoying fair skies and ocean breezes, a large and enthusiastic crowd gathered at the Highlands Center at Cape Cod National Seashore in late July to officially kick off the year-long Two-Column Aerosol Project, or TCAP. About 50 area stakeholders, four staff from the Massachusetts federal and state Congressional delegations, and several DOE officials joined [...]

Between December 2011 and April 2012, a research team led by Los Alamos National Laboratory put ARM’s new Mobile Aerosol Observing System (MAOS) to the test, and it passed with flying colors. Building upon previous system integration and operational testing during summer 2011, the primary goal of the Pajarito Aerosol Couplings to Ecosystems, or PACE, [...]

On March 31, the ARM Mobile Facility stationed at Nainital, India, completed its 9-month deployment for the Ganges Valley Aerosol Experiment. Highlights from the data set include measurements of the subtropical jetstream over the Ganges Valley region; cloud cover and cloud heights for the monsoon period; and water vapor profiles through the various seasons. In addition, measurements from Doppler and Micropulse lidars indicate that aerosol distribution could be much more localized than previously assumed, and also confined to thin layers of a few hundred meters in the lower atmosphere.

On April 30, at about 10:30 p.m, a tornado touched down in Medford, Oklahoma, northwest of the Central Facility at ARM’s Southern Great Plains site. As the storm track moved southeast, ARM's new network of scanning precipitation radars captured the storm signatures in extreme detail. Unfortunately, SGP site staff experienced even more detail, as the path of destruction included their personal property.

On March 31, the ARM Madden-Julian Oscillation (MJO) Investigation Experiment, or AMIE, came to an end, signaling the return of the second ARM Mobile Facility (AMF2) to the United States and a return to routine operations at the ARM site on Manus Island in Papua New Guinea. Researchers have already begun analyzing the AMIE data set.

Large-scale observation network in Korea opens door to new collaborations
Dr. Kyungjeen Park, Korea Meteorological Administration, faces a tremendous responsibility: develop a microscale observing capability to support a major urban atmospheric measurement and modeling project. The project is to take place in the metropolitan area of Seoul City—a megacity of close to 20 million [...]

In 2012, the Atmospheric Radiation Measurement (ARM) Climate Research Facility begins outfitting two new remote climate observation sites at opposite ends of the climate spectrum—one in the harsh arctic environs of Oliktok Point, Alaska, and the other in the mild marine climate of the Azores, in the North Atlantic Ocean. Scientists will use measurements from the new observation sites to study the interactions between clouds and aerosols in these remote regions and how they impact the planet.

In the past year, the Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility deployed 18 new scanning radars at its research sites in Oklahoma, Alaska, and the tropical western Pacific. Today at the American Geophysical Union meeting in San Francisco, Gerald “Jay” Mace, a professor of atmospheric science at the University of Utah, discusses the research implications of these radars during a press conference on new weather and climate technology. Throughout the week, numerous other researchers presented preliminary results using data collected from the new radars.

At this year’s American Geophysical Union Fall Meeting, ARM’s scientific users are presenting dozens of oral and poster sessions describing their research using data from the user facility. DOE's Climate and Environmental Sciences Division will host a Town Hall Meeting Tuesday, December 6, seeking community input for the Green Ocean Amazon 2014 campaign.

A study published in Nature Geoscience this week reveals a trend that atmospheric scientists have been mulling for decades: the effects of aerosols on clouds and rainfall. The findings, based on a 10-year data set of ground-based measurements from the ARM Southern Great Plains site in Oklahoma, corroborate an analysis of NASA global satellite products. Matching results were obtained from simulations by a cloud-resolving model.

The Department of Energy recently announced the selection of new field campaigns that will take place from 2012 through 2013. They include an investigation of marine cloud processes between California and Hawaii using the ARM Mobile Facility onboard the Horizon Spirit cargo ship and aerosol and carbon studies at ARM's Southern Great Plains site in Oklahoma.

Starting October 1, the ARM Mobile Facility began obtaining measurements from the sky above Gan Island, part of the Addu Atoll in the Maldives. Combined with continuous measurements from ARM's permanent site on Manus Island in Papua New Guinea, data collected during AMIE will help scientists analyze the atmospheric phenomena that drive the Madden Julian Oscillation and improve the way this information is used in climate models.
