Corrected Aerosol Chemical Speciation Monitor Data Available for Evaluation
This sample plot from ARM’s Southern Great Plains (SGP) atmospheric observatory shows a selection of aerosol mass or volume concentrations and the corresponding mass or volume concentrations corrected for composition-dependent collection efficiency (CDCE). A new value-added product (VAP) from the Atmospheric Radiation Measurement (ARM) user facility corrects aerosol chemical speciation monitor (ACSM) data for non-unity…

Updated Southern Great Plains Continuous Large-Scale Forcing Data Released
The plots show the time series of the derived large-scale vertical velocity (Omega) in a previous VARANAL version 2 release for July 2018 (top) and in a new release with a bug fixed (middle), and the difference between the two releases (bottom). The bug only affects the time periods after 18 UTC July 21, when…

Value-Added Product Delivers 3D Cloud Positions Based on Stereo Photographs
The figure presents PCCP VAP data from the Southern Great Plains E45 site (Tonkawa, Oklahoma) on March 24, 2020. The upper panel displays the distribution of the reconstructed cloud points by time and height. The colors represent the count of the detected points in the corresponding bin. The bottom left panel is a picture from…

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…

LASSO Gives New Capability to Researchers
For those wanting to run their own simulations, LASSO input observational data are now available The Large-Eddy Simulation (LES) ARM Symbiotic Simulation and Observation (LASSO) team recently released a new set of data bundles focused on shallow convection at ARM’s Southern Great Plains atmospheric observatory. The shallow convection scenario will go on hiatus while the…
