The Arctic Climate and Its Change Revealed by Surface and Cloud Properties and Radiation Fluxes Based on the AVHRR Polar Pathfinder Data Set
The newly available Advanced Very High Resolution (AVHRR) Polar Pathfinder (APP) data set of 18 years from 1982 to 1999, subsampled to a 25 km scale, was used to retrieve cloud amount, cloud optical depth, cloud particle size, cloud temperature, cloud particle phase, surface temperature, surface bro...
