Abstract

This dataset contains monthly 1 degree averages of sea surface temperature data in Obs4MIPS format, from the European Space Agency (ESA)'s Climate Change Initiatve (CCI) Sea Surface Temperature (SST) v2.1 analysis.

The data covers the period from 1981-2017, with the data from 1981 to 2016 coming from the Sea Surface Temperature (SST) project of the ESA CCI project. The data for 2017 were generated using the same approach but under funding from the Copernicus Climate Change Service (C3S).

This particular product has been generated for inclusion in Obs4MIPs (Observations for Model Intercomparisons Project), which is an activity to make observational products more accessible for climate model intercomparisons.

Process overview

This dataset was generated by the computation detailed below.
Title Derivation of the ESA CCI SST v2.1 Obs4MIPS format data
Abstract The Obs4MIPs dataset produced from the ESA Climate Change Initiatve Sea Surface Temperature v2.1 analysis, has been obtained from post-processing of >4 trillion individual skin sea surface temperature (SST-skin) retrievals from infra-red imagery of sensors on Earth observing satellites. The main post-processing steps are: 1) the addition to the SST-skin of adjustments to daily-mean SST at a nominal depth of 20 cm, resulting in an estimate of “SST-depth” 2) the uncertainty-weighted combination of SST-depth values from all the sensors to make a daily-gap-free SST analysis at 0.05 degree latitude-longitude resolution 3) the averaging and uncertainty propagation from the daily SST analysis to monthly 1 degree data In the processing, ERA-Interim fields are used as ancillary information with minimized influence on the SST outcome. Consistent fields of sea ice fraction and sea fraction are also provided. The sea ice fraction is obtained from the Ocean and Sea-Ice Satellite Application Facility [and the sea fraction accounts for ice from the same product and also the presence or not of land in the cell, determined from a surface classification dataset.
