Evaluation of total precipitation from ERA5-Land reanalysis for rain attenuation studies

Abstract

Propagation researchers continuously seek rainfall data to enhance rain attenuation modeling. This paper compares 60-to-1 minute converted long-term rainfall statistics from ERA5-Land reanalysis with experimental measurements from two rain sensors and ITU-R predictions for a specific region in Bolivia. Despite improved spatial resolution, discrepancies arise due to time resolution and grid averaging.
