Outreach Extends to European Geosciences Union
Making its debut at the European Geosciences Union (EGU) General Assembly, the ARM Climate Research Facility “crossed the pond” to attend Europe’s leading forum for Earth and space sciences during the week of April 22-27, 2012, in Vienna, Austria. Participating in the meeting for the first time, ARM Facility staff visited with a steady stream…

ARM Mobile Facility Completes Aerosol Campaign in India
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…

Aerosol Optical Depth Measurements Available as Value-Added Product
Aerosol optical depth (AOD) is a measure of the total aerosol burden in the atmosphere. The spectral dependence of AOD, typically described by the Angstrom exponent, is also an indicator of particle size. Small Angstrom exponent values (near zero) indicate presence of large particles, and vice versa. The AOD value-added product (VAP) provides both the…

Moving on Up: Merged Sounding Data Now a Value-Added Product
The Merged Sounding evaluation product has moved into the ARM Data Archive as a value-added product (VAP). This Merged Sounding VAP, initially designed by Dr. Gerald Mace, was modified by software developer David Troyan under the scientific direction of Michael Jensen to better serve the ARM community. Data are available for the following sites: Southern…

New Aerosol Best-Estimate Data Available as Value-Added Product
The Aerosol Best Estimate (ABE) value-added product (VAP) provides best-estimate time series of total column aerosol optical depth (AOD) and the associated column Angstrom exponent, as well as time/height profiles of aerosol extinction, single-scattering albedo, asymmetry parameter, and Angstrom exponents above the Central Facility at the ARM Southern Great Plains (SGP) site. As inputs, ABE…

AMIE Comes to an End on Manus and Gan Islands
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…

Gone Fishin’—Larry Jones, Stalwart of ARM Tropical Western Pacific Site Office, Retires
After 15 years with the management team for ARM’s Tropical Western Pacific site office, Larry Jones is saying goodbye to his co-workers at Los Alamos National Laboratory and colleagues throughout the ARM Facility. He said that ARM’s overall purpose toward improving climate science made him proud of the work he did every day, and he…

Pilot Phase of Balloon-Borne Greenhouse Gas Sampling Underway
Each ARM site launches four balloon-borne sounding systems, or weather balloons, each day. The measurements they provide—temperature, pressure, humidity, and wind speed—are the backbone of many atmospheric-related research efforts. At the ARM Southern Great Plains site, operations personnel have conducted these launch duties for nearly 20 years. In mid-January, SGP staff shared their extensive balloon-launching…

Arctic Storm Samples Show Relationship Between Sea Ice and Precipitation Over Land
As an important component of Earth’s climate system, sea ice has a particularly strong influence on the Arctic sea surface temperature, evaporation, and reflectivity, or “albedo.” The critical relationship among sea ice, evaporation, and precipitation is linked to a number of climate change effects. At the American Geophysical Union meeting in December 2011, scientists from…
