Roxane Desire (MeteoFrance): Detection of snow, ice and supercooled water clouds
Competency Framework
WMO Satellite Skills
Description
Roxane Desire shows the best RGBs for detection of typical winter weather phenomena: snow, ice and supercooled water clouds.
Content
With the operational deployment of MTG, there are now various methods available for detecting snow on the ground. RGB products, in particular, provide high-contrast images that help distinguish snow on the ground from the underlying surface, low clouds, or ice clouds. We will also explore some important nuances to consider. Finally, still in the context of winter-related issues, we will discuss how these same RGB products can be used to detect supercooled water clouds, which can be responsible for ground ice formation or aircraft icing.
