The MWR profiles are statistical retrievals that utilize a neural network. This retrieval uses both zenith and off-zenith data. The algorithm was developed by Radiometrics, Inc. for the Norman area.
Credit: The Atmospheric Emitted Radiance Interferometer (AERI) is provided by by the U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) program. The AERI profiles are statistical retrievals that use a combination of linear regression and empirical orthogonal functions. The algorithm was developed by Greg Blumberg (OU School of Meteorology) as part of his master's thesis. Note that this retrieval is only valid in clear-sky scenes where the AERI's hatch is open.
The MWR and AERI are passive radiometers, and have their greatest sensitivity to the temperature and humidity structure near the surface (i.e., in the lowest 1-2 km). Both have some sensitivity up to 4 km, but neither should be used above 4 km (data above this level are a result of the climatology used to develop each retrieval). Note that the two retrievals, which were developed by different people, used different prior datasets (i.e., historical radiosonde databases) in the development of the retrieval.
