Bendix, J., Thies, B., Cermak, J., & Schulz, H. M. (2012). 1 Km Fog and Low Stratus Detection Using Pan-sharpened Msg Seviri Data : Volume 5, Issue 3 (26/06/2012). Retrieved from

Description: Laboratory for Climatology and Remote Sensing, Faculty of Geography, Philipps-University, Marburg, Germany. In this paper a new technique for the detection of fog and low stratus in 1 km resolution from MSG SEVIRI data is presented. The method relies on the pan-sharpening of 3 km narrow-band channels using the 1 km high-resolution visible (HRV) channel. As solar and thermal channels had to be sharpened for the technique, a new approach based on an existing pan-sharpening method was developed using local regressions. A fog and low stratus detection scheme originally developed for 3 km SEVIRI data was used as the basis to derive 1 km resolution fog and low stratus masks from the sharpened channels. The sharpened channels and the fog and low stratus masks based on them were evaluated visually and by various statistical measures. The sharpened channels deviate only slightly from reference images regarding their pixel values as well as spatial features. The 1 km fog and low stratus masks are therefore deemed of high quality. They contain many details, especially where fog is restricted by complex terrain in its extent, that cannot be detected in the 3 km resolution.
