The sources of data are satellite (AVHRR) and in situ platforms (i.e., ships and buoys), and the specific datasets employed may change over. At the marginal ice zone, sea ice concentrations are used to generate proxy SSTs. A preliminary version of this file is produced in near-real time (1-day latency), and then replaced with a final version after 2 weeks. Note that this is the AVHRR-ONLY DOISST, available from Oct 1981, but there is a companion DOISST product that includes microwave satellite data, available from June 2002. time_coverage_start: 20081001T000000Z time_coverage_end: 20081002T000000Z uuid: 4b8c732c-18f4-4398-a00d-aca52a6b5922 Unlimited_Dimension: time

Sea ice and in-situ data used also are 'near real time' quality for recent period. SST (bulk) is at ambiguous depth because multiple types of observations are used. source: NAVO-L2P-AVHRR17_G,NAVO-L2P-AVHRR18_G,GTS_SHIP-NCEP-IN_SITU,GTS_BUOY-NCEP-IN_SITU,MMAB_50KM-NCEP-ICE _ChunkSizes: 1, 720, 1440
