He and the other authors use multiple datasets to see where the evidence shows conditions have gotten drier or wetter. The meteorological data include precipitation, temperature, solar radiation and other ground- and space-based measurements. "These types of tools are absolutely critical to helping us address and offset some of the impacts anticipated, whether it be from population growth, climate change or just increased water consumption in general.". Development of the drought/wetness products was funded by NASA's Applied Sciences-Water Resources, Terrestrial Hydrology, and GRACE-FO Science Team programs. JPL managed the mission's implementation and operations. A new NASA study finds that the recent drought that began in 1998 in the eastern Mediterranean Levant region is likely the worst drought of the past nine centuries. The entire collection will be aviable at the GES DISC until June 30, 2020. The GRACE and GRACE-FO satellite-based maps are among the essential datasets used by the authors of the U.S. Drought Monitor, the premier weekly map of drought conditions for the United States that is used by the U.S. Department of Agriculture and the Federal Emergency Management Agency, among others, to evaluate which areas may need financial assistance due to losses from drought. › Learn more about the GRACE mission: http://www.csr.utexas.edu/grace/ | http://grace.jpl.nasa.gov/› NASA Data Reveal Major Groundwater Loss in California →› NASA Satellites Unlock Secret to Northern India's Vanishing Water› The National Drought Mitigation Center →, Texas Drought Visible in New National Groundwater Maps, › NASA Data Reveal Major Groundwater Loss in California →, › NASA Satellites Unlock Secret to Northern India's Vanishing Water, › The National Drought Mitigation Center →. A study released in Science Advances Wednesday finds strong evidence for severe, long-term droughts afflicting the American Southwest, driven by climate change.A megadrought lasting decades is 99 percent certain to hit the region this century, said scientists from Cornell University, the Lamont-Doherty Earth Observatory of Columbia University and the NASA Goddard Institute for Space Studies. The MODIS NDVI layer is a measure of the greenness and health of vegetation. Related Links: Measuring Vegetation (NDVI & EVI) For the purposes of this Web site, our definition most closely resembles that of an agricultural drought. The latest groundwater map, released on Nov. 29, shows large patches of maroon over eastern Texas, indicating severely depressed groundwater levels. "I think you'll see the GRACE-FO monitoring products used in combination with the forecasts," Wardlow said. But for longer-term outlooks on drought severity—or, conversely, flood risk in low-lying areas—groundwater is the metric to watch, said Rodell. jane.j.lee@jpl.nasa.gov, This website is produced by the Earth Science Communications Team at, Site Editor: The model then produces, among other outputs, time-varying maps of the distribution of water at three depths: surface soil moisture, root zone soil moisture (roughly the top three feet of soil) and shallow groundwater. Randal Jackson This layer is part of the GCOM-W1 AMSR2 Level-3 Snow Water Equivalent (SWE) data set, which contains snow water equivalent (SWE) data and quality assurance flags mapped to the Northern and Southern Hemisphere 25 km Equal-Area Scalable Earth Grids (EASE-Grids). Both the Center for Advanced Land Management and the National Drought Mitigation Center are based in UNL's School of Natural Resources, and they are working with international partners, including the U.S. Agency for International Development and the World Bank, to develop and support drought monitoring using the GRACE-FO global maps and other tools in the Middle East, North Africa, South Africa, South East Asia and India. Note that the Mississippi and Missouri river watersheds are still quite moist from persistent winter and spring rains. "They represent the accumulation of months or years of weather events."
