New Cloud Radar Products Available for CACTI Campaign
This shows the XSACRGRIDRHI CACTI product with two-dimensional horizontal-distance-versus-vertical-height gridded radar reflectivity when the azimuth angle is 90 degrees (east-to-west scan). The Atmospheric Radiation Measurement (ARM) user facility released new cloud radar value-added products (VAPs) from the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign. With these VAPs, scientists can more easily use corrected…

Reprocessed Cloud Radar Spectra Data Released for CACTI Campaign
The top right graphic is a time-versus-height image of KAZR reflectivity from the CACTI field campaign during an hourlong period on January 24, 2019. At top left, the spectrogram in height is associated with the time indicated by the dashed blue vertical line in the reflectivity image, 3.47 minutes past the hour. At bottom right,…

New Quality Control Aerosol Optical Depth VAP Released
These time series show the combined aerosol optical depth (AOD, green) and its four individual components (red, blue, wine, and cyan) during a three-hour period on May 11, 2008, at ARM’s Southern Great Plains atmospheric observatory. This example defines a “favorable” case in which all four individual AODs are assessable and the spread between them…

New Cases and High-Frequency Observations Released for LASSO
The Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) data set has grown yet again. Seventeen new cases are now available from the 2019 shallow convection season at the Atmospheric Radiation Measurement (ARM) user facility’s Southern Great Plains (SGP) atmospheric observatory. The current LASSO data set focuses on shallow convection with LES output provided…

ARM Produces Its First 3-Dimensional Large-Scale Forcing Data
This schematic showing ARM’s Southern Great Plains atmospheric observatory illustrates the difference between VARANAL and VARANAL3D. The Atmospheric Radiation Measurement (ARM) user facility has made available its first three-dimensional (3D) large-scale forcing data using a 3D constrained variational analysis approach, known as VARANAL3D. Initially, VARANAL3D evaluation data are available from two field campaigns at ARM’s…
