AVHRR Pathfinder version 5.3 level 3 collated (L3C) global 4km sea surface temperature (sea_ice_fraction variable is part of this CDR although it is considered auxiliary data). CLIMATE APPLICATIONS: This CDR is used by an international community of scientists (https://www.ghrsst.org/ and others) to monitor the global ocean sea surface temperatures through the generation of level-4 climatology and daily optimally interpolated SST products, to give scientists valuable insights into ocean ecology by helping them to monitor coral reef stress, El Nino La Nina cycles that influence a wide range of weather conditions, to characterize local habitats, ocean current patterns and for college and high school training to study different oceanographic processes..
