Atmospheric Emitted Radiance Interferometer Product Expands to 4 ARM Campaigns

Published: 21 August 2023

Three graphs show temperature, relative humidity, and water vapor mixing ratio between 55.0 and 56.0 (jday).
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 campaigns conducted by the Atmospheric Radiation Measurement (ARM) user facility:

Note: The data from ACE-ENA’s June–July 2017 and January–February 2018 intensive observational periods are part of a larger AERIoe data set for ARM’s Eastern North Atlantic (ENA) atmospheric observatory. The new ENA data, which are from June 2017 through March 2018, are now available.

AERIoe provides boundary-layer profiles of temperature and water vapor mixing ratio and liquid cloud retrievals. This VAP helps retrieve profiles in both clear and cloudy conditions so users can better understand the processes occurring in the boundary layer.

One advantage of AERIoe is the high temporal resolution of the thermodynamic profile retrievals in the boundary layer. These retrievals provide new information about the boundary layer’s evolution, which is difficult to measure. Another benefit of AERIoe is that its liquid water path retrievals in optically thin clouds allow for better quantification of microphysical properties in clouds such as shallow cumuli.

AERIoe ran at 20-second temporal resolution for the ENA and CACTI, but at 5 minutes for MARCUS and COMBLE to provide timelier retrievals.

More information about AERIoe is available on the VAP web page. Scientists can begin using the new AERIoe evaluation data now.

Access the new AERIoe data in the ARM Data Center. (To download the data, request an account.)

Feedback on the quality and format of these evaluation data is desired. Please send feedback to ARM translator Damao Zhang.
