2015 ARM Best Estimate 2D Data Sets Available
A plot from ARMBE2DGRID shows surface sensible (left) and latent (right) heat fluxes (unit: W/m2) from July 2015. Data sets for ARM Best Estimate 2-dimensional Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) are available now for year 2015. The primary goal of these two data sets is to provide 2D spatial data…

SACR ADVance Quasi-Vertical Profile Evaluation Product Released
The Scanning ARM Cloud Radar ADVance Quasi-Vertical Profile (SACR-ADV-QVP) provides a quasi-vertical representation of azimuthal-averaged polarimetric variables such as differential reflectivity, specific differential phase and correlation coefficient, and linear depolarization ratio to reveal important signatures in ice and mixed-phase clouds. SACR-ADV-QVPs are produced using a sequence of plan-position-indicator (PPI) scans. The second-generation SACR (SACR2) is…

ARM Data Discovery Tool Provides New Data Delivery Methods
The updated ARM Data Discovery Tool features three new data delivery options: Globus, THREDDS, and Dropbox. All the data collected through the ARM Climate Research Facility have to go somewhere, but it’s not easy to pack them all in—or deliver them from—one spot. Every month, hundreds of users access the ARM Data Archive to download…

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…
