GPM DAILY
Datasets: Global Precipitation Measurement
Description: Global Precipitation Measurement (GPM) is an international satellite mission to provide next-generation observations of rain and snow worldwide every three hours. NASA and the Japanese Aerospace Exploration Agency (JAXA) launched the GPM Core Observatory satellite on February 27th, 2014, carrying advanced instruments that set a new standard for precipitation measurements from space. The data they provide is used to unify precipitation measurements made by an international network of partner satellites to quantify when, where, and how much it rains or snows around the world.

Additional Processing
- The GPM Daily dataset hosted on Climate Engine is sourced from the 30-min data. These data are summed to daily based on 0 UTC time zone.
- This collection contains provisional products that are regularly replaced with updated versions when the data become available. This transition typically occurs about 1-2 years out.
