Abstract: A computerized method for generating a two-dimensional fog map of a region from a near-ground sensors network of commercial microwave links (CMLs), the region is virtually segmented to a grid of multiple pixels, the method comprises: collecting received signals levels from the CMLs, deriving the links' attenuation that are spread within multiple pixels of the region; calculating the fog induced attenuation attribute for each pixel out of a plurality of pixels of the region based on the microwave attenuation information and deciding if exists; wherein the plurality of pixels belong to the multiple pixels; and generating the two-dimensional fog map of the region based, at least in part, on the plurality of microwave attenuation attributes and the topography of the region; improving the 2-D fog map using information from other types of sensors, if exist.
