NASA’s Precipitation Measurement Missions consist of TRMM and GPM. The Global Precipitation Measurement Mission (GPM) is an international satellite mission launched by NASA and JAXA on Feb. 27th, 2014 that is setting new standards for precipitation measurements worldwide. Using a network of satellites united by the GPM Core Observatory, GPM expands on the legacy of the Tropical Rainfall Measuring Mission (TRMM, 1998 - 2015) by providing high quality estimates of Earth’s rainfall and snowfall every 30 minutes.

The Global Precipitation Measurement (GPM) mission has several cross-cutting application areas which contribute to and enhance our understanding of weather forecasting, disasters, ecology, health, water and agriculture and energy. Using advanced space-borne instruments, GPM measures light rain to heavy rain and falling snow, producing a near-global view of precipitation every 30 minutes. Through improved measurements of rain and snow, precipitation data from the GPM mission is used by a diverse range of applications and user communities at local to global scales to inform decision making and policy that directly benefits society.
GPM Flies Over Tropical Cyclone Florence
Download in High Resolution from the NASA Goddard Scientific Visualization Studio GPM passed over Tropical Storm Florence on September 7, 2018. As the camera moves in on the storm, DPR's volumetric view of the storm is revealed. A slicing plane moves across the volume to display precipitation rates throughout the storm. Shades of green to red represent liquid precipitation. Frozen precipitation is shown in cyan and purple. NASA's Global Precipitation Measurement mission or GPM core observatory satellite flew over Tropical Storm Florence on September 7, 2018. At that time, the storm was...
NASA Rainfall Data and Global Fire Weather
The Global Fire WEather Database (GFWED) integrates different weather factors influencing the likelihood of a vegetation fire starting and spreading. It is based on the Fire Weather Index (FWI) System, which tracks the dryness of three general fuel classes, and the potential behavior of a fire if it were to start. Each day, FWI values are calculated from global weather data, including satellite rainfall data from the Global Precipitation Measurement (GPM) mission.
Using Precipitation Data to Track Cholera
Diarrheal diseases such as cholera continue to be a public health threat. Prediction of an outbreak of diarrheal disease, specifically cholera, following a natural disaster remains a challenge, especially in regions lacking basic safe civil infrastructure such as water, sanitation and hygiene (WASH). The underlying mechanism of a cholera outbreak is associated with disruption in the human access to safe WASH infrastructure that results in the population using unsafe water containing pathogenic vibrios. Presence and abundance of Vibrio cholerae, the causative agent of cholera, are related to modalities of the environment and regional weather as well as the climate systems.
