ESA Sea Surface Temperature Climate Change Initiative (SST_cci): Level 4 Analysis product, version 3.0
Abstract
This dataset provides daily-mean sea surface temperatures (SST), presented on global 0.05° latitude-longitude grid, spanning 1980 to present. This is a Level 4 product, with gaps between available daily observations filled by statistical means.
The SST CCI Analysis product contains estimates of daily mean SST and sea ice concentration. Each SST value has an associated uncertainty estimate.
The dataset has been produced as part of the version 3 Climate Data Record (CDR) produced by the European Space Agency (ESA) Climate Change Initiative Sea Surface Temperature project (ESA SST_cci). The CDR accurately maps the surface temperature of the global oceans over the period 1980 to 2021 using observations from many satellites, with a high degree of independence from in situ measurements. The data provide independently quantified SSTs to a quality suitable for climate research.
Data from 2022 onwards are provided as an Interim Climate Data Record (ICDR) and will be updated daily at one month behind present. The Copernicus Climate Change Service (C3S) funded the development of the ICDR extension and production of the ICDR during 2022. From 2023 onwards the production of the ICDR is funded by the UK Earth Observation Climate Information Service (EOCIS) and Marine and Climate Advisory Service (MCAS).
This CDR Version 3.0 product supersedes the CDR v2.1 product. Compared to the previous version the major changes are:
* Longer time series: 1980 to 2021 (previous CDR was Sept 1981 to 2016)
* Improved retrieval to reduce systematic biases using bias-aware optimal methods (for single view sensors)
* Improved retrieval with respect to desert-dust aerosols
* Addition of dual-view SLSTR data from 2016 onwards
* Addition of early AVHRR/1 data in 1980s, and improved AVHRR processing to reduce data gaps in 1980s
* Use of full-resolution MetOp AVHRR data (previously used ‘global area coverage’ Level 1 data)
* Inclusion of L2P passive microwave AMSR data
