Broadband Irradiance VAPs Now Running at New SGP Extended Facilities
Data plots are shown for extended facilities E39, E40, and E41 located near Lamont, Oklahoma, for the best-estimate total downwelling shortwave irradiance from QCRAD. Two value-added products (VAPs)—Data Quality Assessment for ARM Radiation Data (QCRAD) and Radiative Flux Analysis (RADFLUX)—are now running at the new extended facilities at the ARM Climate Research Facility’s Southern Great…

Continuous Large-Scale Forcing Data Now Available for Cloud Modeling From Southern Great Plains
The seasonal cycle of Southern Great Plains domain-averaged latent heat (LH) and sensible heat (SH) fluxes is shown by using QCECOR-only (QCECOR), BAEBBR-only (BAEBBR), and both QCECOR and BAEBBR data (merged) averaged from 2004-2015, and the impact to the derived large-scale vertical velocity (omega). Version 2 of the continuous forcing value-added product uses the merged…

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…

Two New Data Products Available from the Radar Wind Profiler
Time-height images are shown here of the wind speed at a uniform 10-minute and 50-meter resolution from the radar wind profilers, part of the instrumentation at four observing facilities at the Southern Great Plains megasite. The facility name is shown in the top left corner in each panel. The ceilometer-recorded first cloud base height (red)…
