Comparative evaluation reveals variable detection accuracy across satellite precipitation products for extreme storms, highlighting the need for improved retrieval algorithms.

Key Points

To evaluate the reliability, uncertainty, and accuracy of four high-resolution satellite precipitation products in detecting extreme precipitation events compared to radar-gauge reference data.
Evaluated four satellite-derived precipitation datasets: CMORPH, PERSIANN, TMPA-RT, and TMPA-V6 across the central United States.
Used Stage IV radar-based, gauge-adjusted precipitation data as the ground reference benchmark.
Assessed performance across multiple verification metrics, including probability of detection, false alarm ratio, and volumetric rainfall accuracy at varying extreme precipitation thresholds.
CMORPH and PERSIANN demonstrated a higher probability of detecting extreme rain events and identified greater rainfall volumes than TMPA-RT and TMPA-V6, but exhibited higher false alarm ratios and false alarm volumes.
All four satellite products missed a substantial volume of rainfall, and detection accuracy deteriorated systematically across all products as precipitation thresholds increased.
