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…

New Release of Reprocessed QCECOR Data
A new protocol for the QCECOR VAP at Lawrence Livermore National Laboratory has been developed. Quality-Controlled Eddy Correlation Flux Measurement (QCECOR) value-added product data were reprocessed for all the stations at the Southern Great Plains (SGP) site from year 2003 to the end of year 2015. The QCECOR data provide surface sensible and latent heat flux…

New Radiative Flux Analysis VAP Now Operational
Radiative flux analysis data of irradiance and cloud fraction are shown here for the Southern Great Plains. The Radiative Flux Analysis VAP is an implementation of a series of algorithms that estimate clear-sky broadband surface irradiances, cloud fraction, optical depth, cloud transmissivity, and cloud radiative effects. This VAP is an updated version of the Shortwave…
