The high latitude regions are characterized by a lack of in situ observations, decreasing ice cover and strong sensitivity to climate changes. It is therefore important to secure the availability of accurate and reliable satellite SST observations in the high latitudes. The dry atmosphere, presence of sea ice in the Marginal Ice zone, the extended periods with cloud cover and the lack of in situ observations makes the retrieval of sea surface temperature observations from satellite a challenging task. The High Latitude SST TT focuses upon validating and improving the satellite retrievals in the high latitude region(s). In addition, the TT facilitates the use of existing in situ observations and encourages the community to deploy new drifting buoys and other in situ observations.
