LASSO Alpha 2 Supplement Includes 2015 Case Dates
Plots from the Alpha 2 supplement show observed versus simulated cloud fraction for simulation number 13 on June 6, 2015. The plots show observed cloud fraction (top panel) retrieved from the Active Remote Sensing of CLouds (ARSCL) product using the Ka-Band ARM Zenith Radars (KAZRARSCL) product, the simulated cloud fraction (middle panel) based on large-eddy…

Quality Controlled Eddy Correlation Flux Measurement Data Now Updated for SGP
The protocol for the QCECOR VAP workflow is shown here. Two more years of data have been processed for the Quality Controlled Eddy Correlation (QCECOR) value-added product (VAP). This VAP provides improved surface turbulence flux measurements to the ARM user community. Data now extend from 2003 to October 2017 for all systems at the Southern Great…

KASACR Data Quality Masks Value-Added Product Now Available in Evaluation
Evaluation data for the Ka-Band Scanning ARM Cloud Radar (KASACR) Data Quality Masks are now available from the Aerosol and Cloud Experiments in the Eastern North Atlantic (ACE-ENA) field campaign conducted in June and July 2017. The specific dates covered in this data set are June 18 through July 31, 2017. Data quality masks help…

Aerosol Optical Properties VAP Now Available
The first plot shows the aerosol extensive property of light absorption for nominally “red,” “green,” and “blue” light over a two-week period at Ascension Island. The second plot shows the wavelength dependence of aerosol absorption—an intensive property—which describes the nature rather than the abundance of the absorption. The Aerosol Optical Properties (AOP) value-added product (VAP)…

New Version of Python ARM Radar Toolkit Available
Plots of differential reflectivity (top) and reflectivity factor are shown from the X-Band Scanning ARM Precipitation Radar on Graciosa Island in the Azores. Py-ART has a new experimental reader allowing the new format to be read. The latest version of the Python ARM Radar Toolkit (Py-ART), an open-source architecture for interacting with radar data in…

ARM Best Estimate 2D Data Sets Available for 2004 to 2010
ARMBE2DGRID surface sensible (left) and latent (right) heat fluxes are shown from July 2010. Data sets for the years 2004 to 2010 for ARM Best Estimate 2-dimensional (2D) Gridded Surface (ARMBE2DGRID) and ARM Best Estimate Station-based Surface (ARMBESTNS) are available in the ARM Data Center. The primary goal of these two data sets is to…

Microwave Radiometer Retrieval Data Available for LASIC Field Campaign
Precipitable water vapor (PWV) and liquid water path (LWP) data are seen for the main ARM Mobile Facility site on Ascension Island on July 22, 2017. The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has now been processed for the full Layered Atlantic Smoke Interactions with Clouds (LASIC) field campaign. This VAP gathers column precipitable…

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…

Version 2 of the Continuous Large-Scale Forcing Data Now Available
Sample plots are shown here from the Southern Great Plains domain-averaged precipitation measurements from Arkansas-Red Basin River Forecast Center and the corresponding vertical velocity based on variational analysis for June 2015. Updated November 2017: Data are now available for the Southern Great Plains atmospheric observatory for the year 2015. The data sets are in netCDF format.…
