Microwave Radiometer Retrievals VAP Available for New Set of ARM Campaigns

Microwave Radiometer Retrievals quicklook image from CACTI campaign on April 27, 2019, shows brightness temperature, precipitable water vapor, and liquid water path — This Microwave Radiometer Retrievals (MWRRET) quicklook image provides information from the Cloud, Aerosol, and Complex Terrain Interactions (CACTI) field campaign on April 27, 2019. The image shows (a) observed brightness temperatures at 23.8 GHz (blue) and 31.4 GHz (red); (b) retrieved precipitable water vapor from the physical method (blue) and statistical method (green); and (c) retrieved liquid water path from the physical method (blue) and statistical method (green).

The Microwave Radiometer Retrievals (MWRRET) value-added product (VAP) has been processed for the following Atmospheric Radiation Measurement (ARM) user facility field campaign operations:

Cloud, Aerosol, and Complex Terrain Interactions (CACTI), September 2018 to May 2019 in Argentina
Marine ARM GPCI Investigation of Clouds (MAGIC), October 2012 to September 2013 between California and Hawaii
Measurements of Aerosols, Radiation, and Clouds over the Southern Ocean (MARCUS), October 2017 to March 2018 between Australia and Antarctica.

MWRRET retrieves column precipitable water vapor and liquid water path—both important variables to understanding radiative transfer in the atmosphere and clouds—from ARM’s 2-channel microwave radiometers (23.8 and 31.4 GHz). The VAP uses a physical retrieval methodology and bias correction that provides improved retrievals over the standard statistical coefficient method.

Feedback on the VAP can be sent to ARM translator Damao Zhang.

More information on MWRRET is available on the VAP web page. To access these data, log in to the ARM Data Center. (Go here to request an account.)
