At the end of a string tied to the weather balloon, a small sensor package, called a radiosonde, contains the “brains” for measuring atmospheric temperature, pressure and humidity. ARM file image. As part of the Balloon Borne Sounding System, radiosondes launched at the the ARM Climate Research Facility sites are supplied by Vaisala, one of…

Each data stream is now presented on its own web page, and is cross-linked back to its instruments and primary measurement web pages. ARM file image. In early February, the arm.gov website took one more step towards the goal of helping users access data. The ARM Climate Research Facility website staff published a significant reorganization…

A key addition to the ARM Climate Research Facility scientific infrastructure is ready to roll…literally. In February, the ARM Mobile Facility (AMF) is being packed up and shipped from Richland, Washington, to the Point Reyes National Seashore north of San Francisco, California. There, it will be reassembled in preparation for its first deployment as part…

These full spectrum plots show radiance data collected by the SWS at five time intervals over the course of four consecutive days. The scattering profiles indicate three cloudy days (Nov. 21-23) and one clear day (Nov. 24). ARM file image. From November 19, 2004, to December 17, 2004, a new Shortwave Spectrometer (SWS) was deployed…

Challenges presented by the remoteness and environmental conditions at the ARM Climate Research Facility’s Tropical Western Pacific locale are offset by the unique climatological data collected by the measurement instruments located at its sites, including Nauru Island shown above. ARM file photo. Located about 8,000 miles from the United States along the equator near northern…

Difficulties in modeling the effects of clouds on climate arise largely from the insufficient number of observations needed to sufficiently understand cloud processes. Science collaborators at the National Oceanic and Atmospheric Administrations (NOAA) Aeronomy Laboratory have developed a cost effective technique that uses measurements of sunlight scattered by clouds, at various near-infrared wavelengths, to infer…

As part of continuing efforts to improve www.arm.gov, significant updates to the engineering portion of the website have been completed. As a result of this team effort between the ACRF Technical Coordination Office, Engineering Support, and Communications Team staff, the successful redesign now reflects the look of the main website, provides improved communication with users,…

Point Reyes National Seashore, on the California coast north of San Francisco, has been identified as the official location for the first deployment of the DOE’s Atmospheric Radiation Measurement (ARM) Mobile Facility (AMF). As part of a 6-month field campaign beginning in March 2005 to study the microphysical characteristics of marine stratus and, in particular,…

During TWP-ICE, cloud property data will be obtained from numerous research aircraft and a network of surface-based remote sensing sites, including a ship operating in the Timor Sea and numerous ground sites in a 200 km diameter around the ARM Climate Research Facility site in Darwin, Australia. ARM file image. Coming from as far away…
