            "description": "Caught outside during a severe storm? Maybe next time you won’t have to be thanks to the latest addition to NASA’s Earth-observing satellite fleet. The Global Precipitation Measurement (GPM) Core Observatory launched into space on February 27, 2014. The satellite is equipped with two instruments designed to scan our planet's atmosphere and generate 3D maps of rainfall and snowfall. Such measurements are part of an international effort led by NASA and the Japan Aerospace Exploration Agency (JAXA) to improve space-based monitoring of precipitation, with the goal of creating global precipitation data sets that are updated every three hours. Knowing how much rain and snow falls worldwide every few hours will help scientists predict extreme weather events. Watch the video to learn more. || ",

The data will come from the Global Precipitation Measurement mission, an international partnership led by NASA and the Japan Aerospace Exploration Agency. The GPM Core Observatory will launch in early 2014, but the mission goes beyond data gathering data from one satellite. Eleven spacecraft from U.S. agencies and other countries, all carrying similar instruments to measure rainfall, will contribute data to this global rain map. Compiling observations from these eleven sources into one unified global data set is the job of the Precipitation Processing System at Goddard. || ",

This animation shows the scanning capabilities of the GMI and DPR onboard the GPM Core satellite. Heavy rainfall is shown in red and light rainfall in blue. The DPR shows 3D precipitation in a midlatitude storm from two overlapping swaths. The Ka-band frequency scans across a region of 78 miles (125 kilometers) and is nested within the wider scan of the Ku-band frequency of 147 miles (245 kilometers). JAXA and Japan's National Institute of Information and Communications Technology (NICT) built the DPR. The GMI, shown as the flat precipitation values, constantly scans a region 550 miles (885 kilometers) across. The Ball Aerospace and Technology Corporation built the GMI under contract with NASA Goddard Space Flight Center.

NASA's Tropical Rainfall Measuring Mission (TRMM) was launched on Nov. 27, 1997, and for the last decade and a half has enabled precipitation science that has had far reaching applications across the globe.Rain is one of the most important natural processes on Earth, and nowhere does it rain more than across the tropics. Orbiting at an angle to the equator that covers 35 degrees north to 35 degrees south of the equator, TRMM carries five instruments that collectively measure the intensity of rainfall, characteristics of the water vapor and clouds, and lightning associated with the rain events. One of the instruments, the Precipitation Radar, built by NASA's mission partner the Japan Aerospace Exploration Agency (JAXA), is the first precipitation radar flown in space. It returns images of storms that for the first time have revealed close up three-dimensional views of how rainbands in tropical cyclones develop, potentially indicating how strong the storms might become. || ",

Knowing where and how much rain and snow falls globally is vital to understanding how weather and climate impact both our environment and Earth's water and energy cycles, including effects on agriculture, fresh water availability, and responses to natural disasters. Since rainfall and snowfall vary greatly from place to place and over time, satellites can provide more uniform observations of rain and snow around the globe than ground instruments, especially in areas where surface measurements are difficult. GPM's next-generation global precipitation data will lead to scientific advances and societal benefits in the following areas: Improved knowledge of the Earth's water cycle and its link to climate change New insights into precipitation microphysics, storm structures and large-scale atmospheric processes Better understanding of climate sensitivity and feedback processes Extended capabilities in monitoring and predicting hurricanes and other extreme weather events Improved forecasting capabilities for natural hazards, including floods, droughts and landslides. Enhanced numerical prediction skills for weather and climate Better agricultural crop forecasting and monitoring of freshwater resources.For more information and resources please visit the Precipitation Measurement Missions web site. || ",

Other rainfall hotspots included New Jersey (upward of 8 inches in some counties), and upstate New York and Vermont, where satellite estimates show rainfall of up to 5.9 inches in some areas.

            "description": "The Global Precipitation Measurement, or GPM, mission will use an international constellation of satellites to study global rain, snow and ice to better understand our climate, weather, and hydrometeorological processes. One of the critical components of the Earth's hydrological cycle is precipitation. Rainfall is essential for providing the fresh water that sustains life. Water cycling and the future availability of fresh water resources are immense societal concerns that impact every nation on Earth. It affects virtually every environmental issue. Solid forms of precipitation, such as snow and ice, frequently create hazardous conditions during winter storms. Heavy snowfalls severely disrupt transportation networks and temporarily paralyze local economies. Snowfall is also beneficial to many, as it provides the major source of fresh water during arid summer months in many mountainous regions. In the atmosphere, the condensation of water vapor into rain, and then rain into ice, releases vast quantifies of heat. The heat energy drives the wind systems of Earth's atmosphere, and powers violent storms such as hurricanes. In many respects, precipitation is truly the centerpiece of our planet's hydrological cycle, and understanding it is crucial to unraveling many of the uncertainties about Earth's climate.We cannot understand the water and energy cycle or predict weather and climate without an accurate knowledge of the intensity and distribution of global precipitation. Measurement of various aspects of precipitation (e.g. distribution, amount, rates, and the associated heat release) represents one of the most challenging research problems in Earth science. Yet, accurate global precipitation measurements will benefit weather, climate, hydro-meteorological, and applications communities alike. The concept of Global Precipitation Measurement (GPM) is NASA's response to the need for accurate global precipitation measurement. || ",
