. 3 , right column). Two-dimensional space–time PSDs are commonly used in climate and Earth science to analyze the propagation of atmospheric and oceanic waves along longitudes ( Wheeler and Kiladis 1999 ; Lin et al. 2006 ; Orbe et al. 2020 ). The left half of the PSD (negative wavelengths) corresponds to eastward propagating waves and the right half (positive wavelengths) corresponds to westward propagating waves. The two-dimensional space–time PSD shows the energy of the eastward and westward

index, it is in the EPC database for analysis purposes, as a means to efficiently separate the results of this study by fixed surface types. The surface type information obtained from GPROF product provides 14 surface type classes (i.e., ocean, sea ice, five types of vegetation, four types of snow cover, standing water, land/ocean or water coast, and sea ice edge) based on self-similar emissivities derived from TELSEM ( Aires et al. 2011 ; Passive Microwave Algorithm Team Facility 2018 ). In the

based on the attenuation caused by rainfall on microwave (MW) links used for satellite TV broadcasting or cellular networks backhauling are encountering increasing attention. Both of them share the common principle that electromagnetic wave is attenuated by the presence of raindrops. Attenuation depends on frequency that for telecommunication systems is typically in the range 10–40 GHz. While the attenuation mechanism is basically the same, the link geometries have different characteristics
