Patel, NASA Goddard Space Flight Center, Greenbelt, Md. For more information and speaker presentations, please visit the workshop’s website. The GPM Applications team is addressing the workshop participants’ comments and is always interested in additional feedback from the community. Users expressed great interest in this product but also emphasized the need for a consistent, long-term record with which to validate models or compare current rainfall totals to historical events. The Integrated Multi-Satellite Retrievals for GPM (IMERG) product provides high spatial and temporal precipitation data that are available within 4–6 hours of a weather event. The main themes outlined at the workshop focused on data availability, resolution, and consistency. Chris Chiesa from the Pacific Disaster Center demonstrated the center’s DisasterAWARE portal, where TRMM and GPM data are routinely used to provide situational awareness for active disasters around the world. TRMM and GPM precipitation data are also important for disaster response and monitoring organizations, enabling them to better prepare and react to evolving natural disasters and global crises. Near-real-time satellite data are critical for better understanding the spread of vector-borne and waterborne diseases. Antar Jutla of West Virginia University discussed the link between precipitation and temperature in creating an environment for diarrheal diseases, specifically cholera. Ben Zaitchik of Johns Hopkins University described using TRMM and GPM data to track malaria in the Amazon by identifying the key environmental factors for mosquito breeding sites. Public health and ecology researchers provided examples of how near-real-time satellite data are critical for better understanding the spread of vector-borne and waterborne diseases. Participants discussed how products similar to this can help manage water resources and floods. This visualization shows the heavy rainfall throughout northern Texas and across Oklahoma as well as the drought in Southern California. For example, the video below shows rainfall accumulation over the United States for the first half of 2015 as observed by GPM. Panelists also discussed how satellite data on current rainfall and long-term precipitation patterns allow researchers to compare a current drought with past droughts and to model the extent of potential impacts. Agency for International Development, provides early warning and analysis of acute food shortages to help decision makers and relief agencies plan for and respond to humanitarian crises. For example, the Famine Early Warning Systems Network, created by the U.S. Panelists from the food security and agriculture communities emphasized how GPM and other rainfall data are key to better understanding our use of water resources and its implications for food security. Data are available globally on GPM pages. These data depict how rain and snow move around the world, which is critical for understanding Earth’s water and energy cycles. IMERG combines data from the Global Precipitation Measurement (GPM) mission, a constellation of domestic and international satellites, to form a single, seamless map.
