This dataset contains fog frequencies for Europe averaged over all 30 GWSs (general weather situations) after Hess & Brezowsky. Time period covered: 2006-01-01 to 2015-12-31
A description of the data can be found in this paper:

The original fog masks are based on Meteosat Second Generation data that were processed based on the algorithm described in Egli, S., Thies, B. & Bendix, J. (2018). A Hybrid Approach for Fog Retrieval Based on a Combination of Satellite and Ground Truth Data. Remote Sensing. 2018.
