Explore 20 Years of Rain and Snowfall Data from NASA’s Precipitation Missions

IMERG Grand Average Climatology 2001 - 2019
Wednesday, September 9, 2020
A new data product merges data from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission, giving meteorologists and researchers access to a 20-year precipitation record. How much rain and snow fall on Earth in any given year? NASA scientists are answering this question more accurately than ever before and observing precipitation in the most remote places on Earth. And it’s all thanks to an international constellation of satellites. At any given time, instruments onboard about a dozen satellites contribute to a record of the world’s rain and snow

Using the IMERG Long-term Precipitation Dataset for Applications

Using the IMERG Long-term Precipitation Data for Applications
Thursday, October 17, 2019
A long precipitation data set like the new GPM IMERG V06 product is valuable for many applications and for decision-making. Accurate and reliable precipitation records are not only crucial to understanding trends and variability but also for water management resources and food security, ecological management, and weather, climate and hydrological forecasting. Here we present a few highlights showcasing how GPM IMERG is helping a variety of end users make decisions that will benefit society for years to come. GPM IMERG Data Used for Wind Energy Map of average precipitation in north-central...

The Art of Creating Digital Hurricanes

Creating Digital Hurricanes
Wednesday, May 25, 2016
Every day, scientists at NASA work on creating better hurricanes – on a computer screen. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, a team of scientists spends its days incorporating millions of atmospheric observations, sophisticated graphic tools and lines of computer code to create computer models simulating the weather and climate conditions responsible for hurricanes. Scientists use these models to study the complex environment and structure of tropical storms and hurricanes. Getting the simulations right has huge societal implications, which is why one Goddard...

The Evolution of NASA Precipitation Data

The Evolution of NASA Precipitation Data
Tuesday, September 29, 2015
NASA’s global precipitation data and data processing systems have come a long way from the launch of TRMM in 1997 to the ongoing GPM mission. Just before midnight Eastern Daylight Time on June 15, 2015, a fireball appeared over central Africa, streaked across Madagascar, and tracked across the uninhabited Southern Indian Ocean. This was the fiery end of the joint NASA/Japan Aerospace Exploration Agency (JAXA) Tropical Rainfall Measuring Mission (TRMM). TRMM’s homecoming after more than 17 years in orbit also marked the end of the first major satellite mission specifically designed to gather...

GPM's First Global Rainfall and Snowfall Map

GPM's First Global Rainfall and Snowfall Map
Thursday, March 12, 2015
The Global Precipitation Measurement mission has produced its first global map of rainfall and snowfall. Like a lead violin tuning an orchestra, the GPM Core Observatory – launched one year ago on Feb. 27, 2014, as a collaboration between NASA and the Japan Aerospace Exploration Agency – acts as the standard to unify precipitation measurements from a network of 12 satellites. The result is NASA's Integrated Multi-satellite Retrievals for GPM data product, called IMERG, which combines all of these data from 12 satellites into a single, seamless map. The map covers more of the globe than any...

GPM's How-to Guide for Global Rain Maps

GPM's How-to Guide for Global Rain Maps
Thursday, September 4, 2014
In a data-processing room at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, racks of high-powered computers are making a set of maps. They're not the familiar satellite map of farms, forests and cities. Instead, the maps will show what's in the atmosphere above the ground -- falling rain and snow. The data come from the Global Precipitation Measurement mission, an international partnership led by NASA and the Japan Aerospace Exploration Agency. The GPM Core Observatory launched on Feb. 27, 2014, and after an initial check-out period, began its prime mission on May 29. The data...

GPM Data Goes Public

GPM Data from a March 2014 Snostorm
Thursday, September 4, 2014
Image Credit: NASA's Goddard Space Flight Center Download this video in HD formats from NASA Goddard's Scientific Visualization Studio The most accurate and comprehensive collection of rain, snowfall and other types of precipitation data ever assembled now is available to the public. This new resource for climate studies, weather forecasting, and other applications is based on observations by the Global Precipitation Measurement (GPM) Core Observatory, a joint mission of NASA and the Japan Aerospace Exploration Agency (JAXA), with contributions from a constellation of international partner...
