New Report Details One-of-a-Kind Data Quality Assurance Approach
Very few long-running (10+ years) field based measurement programs have the diversity of instruments and data types that the ARM Climate Research Facility does. This month, the ARM data team published a report that goes beyond the narrow definition of data quality assurance by describing its end-to-end approach to data quality, which has evolved since…

Black Forest, Germany, WACR-ARSCL Evaluation Products Now Available
Observations from the 95 GHz W-band ARM Cloud Radar (WACR), Micropulse Lidar, and ceilometer have been combined using the new WACR-Active Remote Sensing of Clouds (WACR-ARSCL) value-added process (VAP) (Kollias and Miller, 2007) to produce cloud boundaries and time-height profiles of cloud location, radar moments, and linear depolarization ratio fields for the ARM Mobile Facility…

Interagency Effort Will Help Dial In Carbon Profiles
Beginning in June, ARM is supporting an offsite field campaign in Iowa that will obtain a variety of carbon dioxide (CO2) measurements to evaluate the accuracy, precision, and utility of CO2 profiles measured by a National Aeronautics and Space Administration (NASA) Differential Absorption Lidar (DIAL). To obtain the atmospheric CO2 measurements, the science team will…

Revised Convective Triggering Mechanism Improves Precipitation Forecast
An improved convective triggering mechanism developed by ARM scientists based on ARM observations was implemented recently in the Global Spectral Model at the Japan Meteorological Agency (JMA) to improve surface precipitation forecasts. The revised triggering mechanism uses a dynamic convective available potential energy generation rate (DCAPE) to control the onset of deep convection. It assumes…

Mobile Facility Anchors Multi-site Aerosol Study in China
In its most complex ARM Mobile Facility (AMF) deployment to date, ARM is coordinating operations and data collection at four different sites for the Aerosol Indirect Effects Study in China. Anchored by the AMF in Shouxian, the campaign also includes a supplemental facility at Lake Taihu and an ancillary facility that will operate in series…

Staying in Sync
Accurate time stamps on data collected at the ARM sites are very important for confidence in using the measurements for research. At the dispersed facilities across the ARM Southern Great Plains site, making sure all the instruments and their associated data logging systems are on the same clock is no easy task. Due to their…
