Compared to previous versions, Version 07 IMERG introduces additional coverage at the high latitudes for the precipitation fields in all Runs -- Early, Late, and Final. IMERG continues to use a merged geosynchronous infrared brightness temperature analysis to provide IR-based precipitation estimates. The requisite analysis (provided by NOAA/NWS/Climate Prediction Center) covers the latitude band 60°N-S, so all inputs are available for IMERG analysis there. At higher latitudes (in both hemispheres) IR-based estimates cannot be included, so the coverage in the complete precipitation fields is based only on the microwave data (and gauge in the Final Monthly). This differs from Version 06, which limited the microwave coverage to gridboxes for which there is no snow/ice on the surface, and previous versions, which entirely excluded microwave data outside the band 60°N-S.
