Posters for the ARM Mobile Facility and ARM Education and Outreach were selected for the 2008 Earth Day display at DOE Headquarters. ARM file photo Earth Day is officially honored each year on April 22, however, many groups sponsor activities throughout the entire month of April. At DOE Headquarters in Washington DC, two ARM posters…

DOE’s Office of Biological and Environmental Research (BER) is now accepting applications to develop innovative methods for observational data analysis and utilize the resulting knowledge from such analyses to improve cloud parameterizations. The intent is to improve the modeling of cloud properties and processes and their impact on the atmospheric radiation balance. Selected research would…

Participants at the CLASIC workshop in March 2008 listen intently to one of the many presenters. In June 2007, ARM led the multi-agency Cloud and Land Surface Interaction Campaign (CLASIC) conducted at the ARM Southern Great Plains site. With scientists beginning to analyze the data, the Cooperative Institute for Mesoscale Meteorological Studies at the University…

As scientific neighbors on Alaska’s North Slope, the ARM site at Barrow operates between NOAA (right) and USGS (left) research facilities. Less than 1 km to the northwest, the shore of Elson Lagoon leads to the Arctic Ocean. After more than a year of discussions and negotiations, ARM has renewed its land use agreement with…

After a long day, participants at the 2008 ARM Science Team Meeting could enjoy Norfolk’s waterside paths, mermaid sculptures, and nautical history. Set against panoramic river views in Norfolk, Virginia, the Eighteenth Annual ARM Science Team Meeting on March 10-14 brought together 270 ARM researchers, ARM infrastructure members, and leading scientists from 10 countries around…

The TCRSR is shown here on the roof of the Radiometer Calibration Facility at the SGP site. Two shadowbands rotate around the radiometer’s sensor, located just inside the smaller shadowband. They reflect light away from the sensor at multiple angles so that it simultaneously records signals of scattered light. A Thin-Cloud Rotating Shadowband Radiometer (TCRSR)…

At an elevation of 5320 meters, this location on Toco Mountain is one of the preferred sites identified by the scout team. ARM file photo. In February, a four-person scout team spent two weeks in Chile conducting initial site surveys and meeting with local contacts in preparation for phase two of the Radiative Heating in…

On the roof of the radar instrument shelter at the ARM Southern Great Plains site, antennas for the W-band ARM Cloud Radar (rectangular white box) and millimeter wavelength cloud radar (conical cylinder) send data to their respective computer systems inside the shelter. ARM file photo. In 2007, ARM established a Radar Focus Group to address…

As reported in late 2006, a total precipitation sensor (TPS) was installed near the ARM North Slope of Alaska (NSA) site in Barrow, to provide measurements of boundary layer (surface to 1000-m altitude) environmental conditions. After falling victim to curious and possibly hungry lemmings and other wildlife in the area, the fiber optic cable used…

In this flight pattern, the Convair-580 takes off from Barrow (BR) after refueling, flies several legs within clouds between 1-2 km high, then returns to base at Fairbanks. ARM file image. With just one month before the start of the Indirect and Semi-direct Aerosol Campaign (ISDAC), the ARM Aerial Vehicles Program (AVP) is finalizing the…
