Jacob L. Høyer works at the Danish Meteorological Institute (DMI) in Copenhagen. He has worked many years with satellite observation of sea surface temperature, ice surface temperatures and sea ice in the high latitudes within Copernicus CMEMS and EUMETSAT OSI-SAF. Recently he has been responsible for developing the first European global climate data record of SST from Passive Microwave (PMW) observations (AMSR-E and AMSR-2) within the ESA CCI program. He is a member of the Sentinel 3 SLSTR Quality Working Group,  S3 Cal/Val Team and the GHRSST science team. In the Copernicus CMEMS SST TAC project he is responsible for producing operational SST products for the Arctic ocean and occasionally goes to the field (Arctic) to collect some in situ observations.  Follow Jacob on twitter: @JacobHoeyer
