The Integrated Multi-satellitE Retrievals for GPM (IMERG) algorithm combines information from the GPM satellite constellation to estimate precipitation over the majority of the Earth's surface. This algorithm is particularly valuable over the majority of the Earth's surface that lacks precipitation-measuring instruments on the ground. Now in the latest Version 6 release of IMERG the algorithm fuses the early precipitation estimates collected during the operation of the TRMM satellite (2000 - 2015) with more recent precipitation estimates collected during operation of the GPM satellite (2014 - present). The longer the record, the more valuable it is, as researchers and application developers will attest. By being able to compare and contrast past and present data, researchers are better informed to make climate and weather models more accurate, better understand normal and extreme rain and snowfall around the world, and strengthen applications for current and future disasters, disease, resource management, energy production and food security.

Overview The GPM Cold-season Precipitation Experiment (GCPEx) was conducted in cooperation with Environment Canada in Ontario, Canada from January 17th to February 29th, 2012. The overarching goal of GCPEx was to characterize the ability of multi-frequency active and passive microwave sensors to detect and estimate falling snow through the collection of microphysical property data, associated remote sensing observations, and coordinated model simulations of falling snow. Through collection of these unique datasets, GCPEx's goal is to improve the GPM snowfall retrieval algorithms. The GCPEx

Overview The Iowa Flood Studies (IFloodS) are a ground measurement campaign taking place in eastern Iowa from May 1 to June 15, 2013. The goals of the campaign are to collect detailed measurements of precipitation at the Earth's surface using ground instruments and advanced weather radars and, simultaneously, collect data from satellites passing overhead. The ground instruments will characterize precipitation -- the size and shape of raindrops, the physics of ice and liquid particles throughout the cloud and below as it falls, temperature, air moisture, and distribution of different size

Vector-borne diseases are responsible for over 17% of all the infectious diseases globally. Many of these diseases are preventable through protective measures, provided local authorities are aware of the potential outbreaks of the responsible vectors. Vectors are living organisms that are able to transmit diseases between humans or from animals to humans. These diseases include but are not limited to cholera, malaria, dengue fever, Zika, schistosomiasis, and West Nile fever.

NASA has a unique and important view of hurricanes around the planet. Satellites and aircraft watch as storms form, travel across the ocean and sometimes, make landfall. After the hurricanes have passed, the satellites and aircraft see the aftermath of hurricanes, from downed forests to mass power loss.

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.
