Two new approaches for the detection of fog/low stratus during daylight are presented. The methods are<br/>
based on second generation space technology from the polar (TERRA/AQUA MODIS) and geostationary<br/>
(MSG-SEVIRI) orbits. The MODIS approach makes use of a threshold technique which relies on eight<br/>
spectral bands. Minimum and maximum fog thresholds are determined by spectral threshold functions<br/>
which are derived from radiative transfer calculations. Validation with SYNOP data points to a good<br/>
performance of the algorithm. The SEVIRI approach profits from spectral and spatial cloud characteristics.<br/>
Fog detection is performed by using dynamic thresholding and a test due to cloud homogeneity.
