MODIS Aqua Level 3 Thermal IR Monthly 4km

The MODIS Aqua and Terra Global Level 3 Mapped Thermal and Mid-IR SST product consists of sea surface temperature (SST) data that are derived from the NASA MODIS sensor on board the Aqua and Terra satellites. SST is derived from the 11 and 12 um thermal IR infrared (IR) bands (MODIS channels 31 and 32) and the 3 and 4 mid-IR bands (MODIS channels 20,21,22 and 23). The data have been mapped to a cylindrical equidistant map projection with 4.63 or 9.26 km spatial bins.

Note: The data is remotely accessed via the PO.DAAC's Thredds server.
