• Description:
  Passive aquatic listeners (PALs) provide high-quality, high-resolution estimates of precipitation over ocean regions, but have been underutilized as a reference data set for the evaluation of satellite-based precipitation estimates (SPEs). PALs are uniquely suited for this purpose due to their 5 km surface listening area when sampling at 1 km depth on drifting Argo Floats, providing rain rate estimates on a spatial scale similar to the native grid spacing of many SPEs. In this study we compare three SPE products (IMERG, CMORPH, and PDIR-Now) to PAL measurements. Evaluations are performed over tropical, extratropical, and global oceans at SPE native spatiotemporal resolution and longer time scales. We find the SPEs to have rain
