Top 5 GPM Research Highlights

Wednesday, February 20, 2019

GPM celebrates its fifth anniversary since launching from Tanegashima Island, Japan on February 27, 2014. This milestone not only marks the launch but also the many scientific research accomplishments that GPM has made in advancing our understanding of precipitation, from light rain to intense thunderstorms, to further our understanding of the water cycle. Here are five of GPM’s most significant research accomplishments and their contributions to weather and climate science in its first five years in space: Snowfall and Cold Season Precipitation An image of GPM’s DPR concept of dual-frequency...

For the past 5 years GPM data has provided critical information to end-users to further our understanding of Earth's water cycle and to facilitate decision‐making at local and global scales. Building on the legacy of TRMM, the use of high‐quality precipitation data provided by GPM, with global coverage, has enabled new science research and data applications to benefit society across a diverse range of applications including water resource and ecological management, operational numerical weather prediction, disease prediction, and disaster modeling and response. Here are five highlights of the...

Using GPM Data for Weather, Climate, and Land Surface Modeling Variations in rain, snow, and other forms of precipitation are an integral part in everyday weather and long term climate trends. Initialization of short-term weather and long-term climate models with accurate precipitation information enhances their prediction skills and extends their skillful lead times. To get the resolution and temporal coverage to measure precipitation across the globe, we often rely on satellite information. Satellite data can play a fundamental role in our ability to monitor and predict weather systems as

Growing human population, increased demand for water and energy, and a changing climate have contributed to concerns of how freshwater resources and food supply and production may be stressed. Both water resource managers and the agricultural community need to know the amount, distribution, timing and onset of seasonal rain and snow to prepare for freshwater shortages and forecast crop yields. Remotely sensed precipitation estimates play a key role in predicting changes in freshwater supply and agricultural forecasting. Specifically, GPM provides advance precipitation measurements on regional

In many areas, energy infrastructure assets, such as power plants and electric grids, can suffer damage or disruption in service due to a variety of climate-related impacts like extreme precipitation, high temperatures, drought, and rising sea levels. For example, warmer temperatures and little rainfall can cause changes in peak streamflow conditions that affect hydropower generation. Heavy precipitation events and flooding can impact a region’s energy infrastructure, including electric grid equipment, which has cascading effects on freshwater supplies and emergency services. The Energy
