Data Type: 3IMERGHH_EARLY_GIS_1DAY

Data Set Long Name: Early IMERG Daily GIS-formatted

Version Number: V07

Data Set Description: This near-realtime dataset provides, in a GIS-friendly format, the surface precipitation estimates and precipitation-phase information covering 24-hour periods at 0.1-degree resolution from June 2000 to the present.  The parent of this GIS product is the half-hour IMERG HDF5 data product.  This GIS product is a zip file that contains two-byte TIFF files accompanied by ESRI WorldFile metadata.  The TIFF files contain scaled units of precipitation accumulation (millimeters) or the percent likelyhood that 100% of the precipitation in a particular gridbox fell as liquid or mixed phase precipitation (i.e., not 100% solid-phase precipitation). The grid covers the entire Earth, 90S to 90N and 180W to 180E although precipitation is not always estimated near the poles.
