Merged Aerosol Size Distribution Product Available for Evaluation
This is an example of the merged size distribution VAP input (SMPS, APS) and output data from November 2021 at the Southern Great Plains atmospheric observatory. The data are averaged to a 1-hour time resolution to improve the VAP data quality. The Atmospheric Radiation Measurement (ARM) user facility currently operates at least four instruments that…

Atmospheric Emitted Radiance Interferometer Product Expands to 4 ARM Campaigns
The figure shows a time series of temperature, relative humidity, and water vapor mixing ratios retrieved from AERIoe for the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign in Argentina on February 24, 2019. The Atmospheric Emitted Radiance Interferometer Optimal Estimation value-added product (AERIoe VAP) is now available in evaluation mode for the following four field…

New and Improved ARM Broadband Radiation Data Now Available
Radiometers operate in mountainous terrain as part of the Surface Atmosphere Integrated Field Laboratory (SAIL) campaign near Crested Butte, Colorado. The campaign took place from September 2021 to June 2023. Photo is by David Chu, Los Alamos National Laboratory. The Atmospheric Radiation Measurement (ARM) user facility’s longtime recommended datastream for broadband surface irradiance measurements is…

Updated: Access New Gridded Cloud Radar Product for COMBLE Campaign
Editor’s note (July 20, 2023): A new KASACRGRIDPPI evaluation release for COMBLE, which uses b1-level calibrated PPI data as input, is now available. Output data from KASACRGRIDPPI are uncalibrated c1-level netCDF files, each comprising gridded observations for a single azimuthal scan. Surveillance scans are gridded for elevations of 0, 0.5, 1, and 2 degrees. Output…

Cloud Microphysics VAP Extended at Southern Great Plains
Sample plots show the primary fields from MICROBASEKAPLUS (liquid water content, liquid effective radius, ice water content, and ice effective radius) on November 21, 2021, at ARM’s Southern Great Plains atmospheric observatory. New evaluation data are available from a value-added product (VAP) that builds upon the Atmospheric Radiation Measurement (ARM) user facility’s historical Continuous Baseline…

Wind Profiles Derived From Motion-Corrected MOSAiC Lidar Data
Using this example of a wind profile scan on a tilted surface, winds are retrieved at height z by interpolating the radial velocities in each beam to height z and then applying the standard wind retrieval technique to the interpolated data. A new value-added product (VAP) developed specifically for the Multidisciplinary Drifting Observatory for the…

New Cloud Microphysics and Sonde Products Available for 2 ARM Campaigns
INTERPSONDE potential temperature output profiles are shown for November 18, 2012, during the Two-Column Aerosol Project (TCAP). The Atmospheric Radiation Measurement (ARM) user facility released two new cloud microphysics and sonde value-added products (VAPs) from the 2012–2013 Two-Column Aerosol Project (TCAP) on Cape Cod, Massachusetts, and the Green Ocean Amazon (GoAmazon2014/15) field campaign near Manaus,…

New ARM Data Epoch Assembled From COMBLE Campaign
In this satellite image of the Norwegian Sea on March 28, 2020, a cold-air outbreak spurs the formation of “cloud streets.” As these broken cloud decks stream southward, they evolve into cellular patterns. In red are the two instrument locations in Norway during ARM’s Cold-Air Outbreaks in the Marine Boundary Layer Experiment (COMBLE). This event…

Your Introductory Guide to TRACER Data
Editor’s note: Michael Jensen, principal investigator for the 2021–2022 TRacking Aerosol Convection interactions ExpeRiment (TRACER), provided the following blog post. Most of the data from the TRacking Aerosol Convection interactions ExpeRiment (TRACER) came from this site in La Porte, Texas. After TRACER’s field operations period ended about eight months ago in the Houston, Texas, area,…
