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.

Current Version: V07B

Early: Early GPM only has forward propagation meaning values are extrapolated. This is the first available data from the GPM model with a 4-hour latency.

Late: Late GPM has both forward and backward propagation (allowing interpolation). This is the second available data with a 12-hour latency.

Final: Final GPM uses monthly gauge data to create research-level products. This is the final data and has 3.5 months latency.
