Oklahoma Mesonet Soil Moisture Product Available for Evaluation
1998 Volumetric Water Content for the station BUTL in the Oklahoma Mesonet for comparison to the Illston 2008 paper. While the relative temporal behavior is replicated, the absolute volumetric water content with the new coefficients derived by the Oklahoma Mesonet (Scott 2013) is significantly lower than before. For example, it is 35% at the 5-cm…

New WACR Radar Data Available for AWARE Campaign
Best estimate reflectivity data from the WACR-ARSCL value-added product are shown here for the AWARE field campaign on January 3, 2016. The W-band ARM Cloud Radar-Active Remotely Sensed Cloud Locations (WACR-ARSCL) provides cloud boundaries and best-estimate time-height fields of radar moments. WACR observations are corrected for velocity aliasing, and then significant detection masks are produced.…

Data Quality Assessment for ARM Radiation Data (QCRAD) VAP Now Operational
An example plot shows diffuse shortwave data at the Azores for the year 2015. The red curve represents physically possible limits; the green and blue curves represent empirically determined limits for indeterminate and bad data respectively. Points identified by a misaligned solar tracker are shown in cyan. The Data Quality Assessment for ARM Radiation Data…
