The Marine Atmospheric Emitted Radiance Interferometer (M-AERI) is a Fourier-transform spectrometer that measures atmospheric and oceanic infrared radiation spectra. From these measurements, a number of environmental variables can be derived. The M-AERI was designed by the UW-Madison Space Science and Engineering Center (SSEC) and is used in the Department of Energy’s Atmospheric Radiation Measurement (ARM) program for various scientific studies of climate and atmospheric processes. In January and February of 2015, a M-AERI was deployed in the Pacific Ocean, near the West Coast of the United States, on the NOAA Ship Ronald Brown, as part of the ARM Cloud Aerosol Precipitation Experiment (ACAPEX). Using the M-AERI observations from ACAPEX, we develop and apply a retrieval algorithm to derive sea surface temperature (SST) and infrared emissivity for various sea states and observing geometries. These observational results are used to validate existing models of sea surface emissivity. The accuracy of these emissivity models is critical for accurate global SST retrievals using satellite observations.
