Session Description

Global and regional climate SST reanalyses and climate data records are essential for monitoring and characterisation of the climate system and its change. Sustained monitoring provides an observational basis for our understanding of climate change and variability, and enables us to place current events into the context of the past. It draws upon information from in situ and satellite observations as well as dynamical reanalyses and climate models. This session aims to highlight the recent advancements in SST climate data records and reanalyses with a particular focus on the observed trends, variabilities and the corresponding uncertainties. This session also welcomes contributions on the use of SST products in climate models for assimilation as well as model evaluations. Comparison and validation of climate simulations using different SST datasets are welcome, in order to provide information to producers to enable them to improve their products for specific applications.

The session will focus on the following: 

  • Advances in observational climate and reanalysis SST products
  • Applications of SST observations and reanalyses in global and regional assessments of climate change and variability
  • Applications of SST observations for assimilation, evaluation and inter-comparisons of climate models and dynamical reanalyses. 
  • Comparison and validation of climate simulations using different SST datasets

Keywords: Climate monitoring, climate data records and reanalyses, climate change and variability, trends, climate-indicators, dynamical reanalyses, climate model simulations.
