Learning about the vertical structure of radar reflectivity using hydrometeor classes and neural networks in the Swiss Alps [PDF]

Atmospheric Measurement Techniques, 2020
The use of radar for precipitation measurement in mountainous regions is complicated by many factors, especially beam shielding by terrain features, which, for example, reduces the visibility of the shallow precipitation systems during the cold season ...
