Casey US DOC; NOAA; National Environmental Satellite Data and Information Service; National Oceanographic Data Center Kenneth.Casey@noaa.gov http://www.nodc.noaa.gov/SatelliteData/Cortad/ WWW:LINK web browser information originator Elizabeth R. Selig Principal Investigator CoRTAD sea ice fraction is derived from Pathfinder 5.3 variable "sea_ice_fraction" This netCDF-4 file contains Weekly-Averaged Sea Ice Fraction Time Series from 1982-2020 and is part of a collection of sea surface temperature (SST) and related thermal stress metrics, developed specifically for coral reef ecosystem applications but relevant to other ecosystems as well. The CoRTAD Version 6 contains global, approximately 4 km resolution SST data on a weekly time scale from 1982 through 2020. In addition to SST, it contains SST anomaly (SSTA, weekly SST minus weekly climatological SST), thermal stress anomaly (TSA, weekly SST minus the maximum weekly climatological SST), SSTA Degree Heating Week (SSTA_DHW, sum of previous 12 weeks when SSTA is greater than or equal to 1 degree C), SSTA Frequency (number of times over previous 52 weeks that SSTA is greater than or equal to 1 degree C), TSA DHW (TSA_DHW, also known as a Degree Heating Week, sum of previous 12 weeks when TSA is greater than or equal to 1 degree C),and TSA Frequency (number of times over previous 52 weeks that TSA is greater than or equal to 1 degree C). The CoRTAD also includes ancillary information on sea ice fraction and wind speeds.
