Representing the first of several planned improvements to the Aerosol Observing System (AOS) at the SGP site, the ARM Climate Research Facility operations staff completed installing a new pump shelter for the system in late September, followed by relocation of the pumps and connection of the electrical hookups in October. Though the enclosure was designed…

Plot Browser, now available through the Data Quality Health and Status (DQ HandS) program, eases viewing by providing lists or thumbnail images of selected data streams. ARM file image. The ARM Climate Research Facility’s Data Quality Office has developed a new way to help data quality analysts, instrument mentors, and site scientists quickly and easily…

An M-PACE researcher launches a radiosonde at Oliktok Point. Several launch periods, spanning at least 5 days each with 4 launches per day, are planned for all four experimental sites (Barrow, Oliktok Point, Atqasuk and Toolik Lake). ARM file photo. During the Mixed-Phase Arctic Cloud Experiment (M-PACE), taking place in October 2004 at the ARM…

This fall, the ARM-Unmanned Aerospace Vehicle Program—specifically, the Proteus aircraft—is participating in the Mixed-Phase Arctic Cloud Experiment (M-PACE) in Alaska. However, several of the aircraft’s onboard instruments have been modified since its last deployment in November 2002. To verify instrument operation and calibration prior deployment as part of M-PACE, in late September 2004, ARM researchers…

During the past several years, the sensitivity of the 8-year old Raman lidar at the ARM Climate Research Facility Southern Great Plains (SGP) site has decreased between a factor of 3-4, resulting in a lower maximum altitude and increased random error in the geophysical properties (such as water vapor mixing ration and aerosol extinction profiles)…

The 1-channel (left) and 2-channel (right) NFOV radiometers are collocated with the infrared thermometer (green stripe) at the SGP Central Facility. Numerous other instruments are situated nearby. ARM file photo. In September 2004, the ARM Climate Research Facility Operations staff installed a new 2-channel Narrow Field of View (NFOV) radiometer at the Southern Great Plains…

Measurements from field instruments, such as the radar wind profiler (center) and radio acoustic sounding system (perimeter) in Barrow, are collected and transmitted by the Site Data System.
