Sea surface temperature
Sea surface temperature monitoring supports ocean weather, climate records, fisheries, coral bleaching alerts, marine heatwave analysis, and thermal-front mapping.[1][2][3]
Thermal infrared radiometry from instruments such as MODIS and VIIRS is a primary high-resolution route for sea-surface skin and subskin temperature, but it requires clear-sky retrieval.[1][3]
Operational SST products such as NOAA OISST blend satellite, ship, buoy, and Argo observations into regular global grids for climate and monitoring use.[2]
Microwave SST has coarser spatial resolution but provides useful cloud-penetrating coverage that complements infrared retrievals.[2][3]
