Summary
Satellite-based precipitation products have significantly advanced applications in hydrology, climate science, and related fields. Despite the significant role of the Global Precipitation Measurement (GPM) mission in monitoring global precipitation dynamics over the past decade, its performance on sub-daily time scales remains insufficiently explored on a global scale. This study provides a continental assessment of the Integrated Multi-satellitE Retrievals for GPM (IMERG) V07B Final Run using extensive hourly ground observations across contiguous United States (CONUS), West Europe, and East Asia. The results demonstrate that IMERG captures precipitation amounts with reasonable accuracy, yielding a median Kling–Gupta efficiency of 0.31 and a median relative bias of 7 %. This bias is primar
