Antarctic satellite composite imagery, 2025.

The University of Wisconsin-Madison creates composite satellite imagery over the Antarctic and adjacent Southern Ocean as a part of the Antarctic Meteorological Research Center and Antarctic Meteorological Research and Data Center projects. The imagery is generated by combining geostationary and polar-orbiting satellites via a mosaic process outlined in Lazzara et al., 2003, Lazzara et al., 2011, and Kohrs et al., 2014. The composites are made in 5 spectral channels: infrared window (~10 micron), longwave infrared (~12.0 microns), shortwave infrared (~3.8 microns), water vapor (~6.7 microns), and visible (~0.65 microns). The temporal resolution increases from 3-hourly to 1-hourly (switch taking place from 2009 to 2013 depending on spectral channel). The spatial resolution increases from 10 km to the current 4 km resolution over the lifetime of the project. The imagery is made available in McIDAS AREA, netCDF, and JPEG file formats.
