Abstract:
A European fog climatology of fog frequency and fog properties which is based on a 10-years time series of NOAA-AVHRR data is under preparation. In this paper, preliminary results are presented. A fog map for 63 days provides a clear distinction of fog frequency in Europe: The pre-alpine basins reveal the highest fog frequency, a secondary maximum is observed for the river valleys of the lower mountain ranges and the fog minimum is located in the transition zone between the maritime coastal fog of the North Sea and the area of continental valley fog of the river valleys. The potential of VIS and MIR data for the calculation of fog optical and microphysical properties are discussed in the scope of a case study.
