NASA Global Precipitation Measurement Mission to Advance Hazard Tracking


November 26, 2013


Taken November 25, 2013, from Global Hazards Atlas, this image displays TRMM data estimating 1-day rainfall accumulation associated with Tropical Cyclone Lehar as it moves out of the Andaman Sea into the Bay of Bengal, approaching the Indian coast. NASA and its partners will shortly launch the next generation of precipitation measurement satellites.

A new international network, or constellation, of eight satellites will provide unprecedented global observations of precipitation from space. The historic breakthroughs behind this achievement belong in large part to the Tropical Rainfall Measuring Mission (TRMM), a joint National Aeronautics and Space Administration (NASA) and Japan Aerospace Exploration Agency (JAXA) satellite launched in 1997 that has advanced precipitation science across the globe.

Expanding on TRMM measurements, NASA is preparing to launch the Global Precipitation Measurement (GPM) instrument in February 2014. In conjunction with the University of Maryland (UMD), NASA organized the 2013 Global Precipitation Measurement Applications Workshop, which took place on November 12 and 13 at the NOAA Center for Weather and Climate Prediction in College Park, Maryland. The goals of the two-day event were 1) to update the earth-science and weather-applications communities on TRMM and GPM, 2) to broaden the discussion to address a range of current and future applications of satellite data, and 3) to collect feedback from users on NASA data products and data access.

As a sponsored speaker, Pacific Disaster Center (PDC) Deputy Executive Director Chris Chiesa participated in the event and chaired a plenary session focusing on hydrological modeling and disaster response. Chiesa presented on PDC’s use of satellite-derived information, including TRMM rainfall estimates and MODIS “hot spot” data for wildfire mapping, and provided information on the Center’s activities around the world. Other plenary sessions explored topics of weather forecasting, water resources, agricultural modeling, food security, ecological forecasting, and public health.

A broad range of United States Government agencies attended the Workshop, including representatives from National Oceanic and Atmospheric Administration (NOAA), U.S. Geological Survey (USGS), the Federal Emergency Management Agency (FEMA), the U.S. Department of Agriculture (USDA), the Department of Defense (DoD), and the U.S. Agency for International Development (USAID). In addition, various universities and private sector companies participated in the workshop. This event is meant to be the first in a series of workshops on this mission to keep the community informed about how GPM is performing and how resulting data are being used.

About PDC:

Pacific Disaster Center (PDC) envisions a safer, more secure world—where populations live in more disaster-resilient communities informed by science and technology, and equipped with sound decision support tools. To help make that vision a reality, PDC is dedicated to supporting evidence-based disaster risk reduction (DRR) efforts by providing actionable information and applications to the public and disaster managers worldwide. PDC, a program managed by the University of Hawaii, was established by the U.S. government in 1996.
