The Probable Maximum Precipitation (PMP) Datasets in Geotiff format at the 0.5-hr, 1-hr, 2-hr, 3-hr, 6-hr, 12-hr, 24-hr, 2-day, and 3-day are statistically derived based on World Meteorological Organization (WMO)’s endorsed Hershfield PMP estimation technique using IMERG’s 30-min precipitation dataset. The Google Earth Engine’s script for assessing and interacting with the datasets is also provided.
