Aerosol Optical Depth Product Generates New Data
The colors represent aerosol optical depths measured at five different wavelengths with the multifilter rotating shadowband radiometer on June 19, 2019, at Oliktok Point, Alaska. New data are now available from the Aerosol Optical Depth value-added product derived from multifilter rotating shadowband radiometer measurements (AOD-MFRSR VAP). AOD is the measure of the total aerosol burden…

Aerosol Optical Depth Data Updated for Azores, Macquarie Island
Measurements from the multifilter rotating shadowband radiometer, seen here at ARM’s Eastern North Atlantic atmospheric observatory, allow users to infer the atmosphere’s aerosol optical depth at each wavelength. Aerosol optical depth (AOD) is the measure of the total aerosol burden in a vertical column of the atmosphere. The AOD value-added product (VAP) has been running…

Three New Value-Added Products Available for MOSAiC Expedition
ARM instruments, including radars and aerosol instruments, operated on an icebreaker in the central Arctic during the 2019–2020 Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition. Photo is by Tercio Silva, then with Hamelmann Communications. The Atmospheric Radiation Measurement (ARM) user facility released three new value-added products (VAPs) from the 2019–2020 Multidisciplinary…

New Data Available From Updated Raman Lidar Value-Added Product
This figure provides sample plots from ARM’s Southern Great Plains Central Facility Raman lidar on May 25, 2020. The top plot shows a time-height cross-section of the merged photon counting rates for the narrow-field-of-view elastic (355 nm) channel. The middle plot shows cloud base height estimates, and the bottom plot shows the so-called “merge flag.”…

Cloud Droplet Number Concentration Product Updated
This sample plot from the Southern Great Plains Central Facility shows the droplet number concentration for October 30, 2019. New data are available from the Droplet Number Concentration value-added product (NDROP VAP), which has been updated to use additional inputs. This will allow NDROP to be available quicker with better retrievals and to be applied…

Updated Surface Spectral Albedo Data Released
This example quicklook from the SURFSPECALB value-added product shows the estimated spectral albedo for the 10- and 25-meter towers at ARM’s Southern Great Plains atmospheric observatory on June 2, 2016. On that date, the surface type for both towers was all vegetation. Updated data from the Surface Spectral Albedo value-added product (SURFSPECALB VAP) are available…
