            "description": "The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission  is a joint Earth-science project launched in 2018 by NASA and the German Research Centre for Geosciences to continue the work of the earlier GRACE mission. It consists of two satellites flying about 137 mi (220 km) apart in the same orbit around Earth, constantly measuring tiny changes in the distance between them. These variations occur because changes in Earth’s gravity, caused by shifting masses such as melting ice sheets, groundwater depletion, and ocean circulation, slightly alter the satellites’ speeds and separation. By precisely tracking these changes, GRACE FO allows scientists to map how water moves across the planet, improving our understanding of climate change, sea-level rise, and global water resources.This visualization uses data from GRACE FO to create an index based on percentile dryness, categorizing the dregree of wetness or dryness within three domains: groundwater storage, root zone soil moisture, and surface moisture. It updates weekly, and extends back over a period of a year from the current week.This visualization is created for use within the Earth Information Center (EIC). || ",

            "description": "Droughts in the U.S. Southwest and Central Plains at the end of this century could be drier and longer compared to drought conditions seen in those regions in the last 1,000 years, according to a new NASA study.The study, published Feb 12 in the journal Science Advances, is based on projections from several climate models, including one sponsored by NASA. The research found the risk of severe droughts in those regions would increase if human-produced greenhouse gas emissions continue to increase.\"Natural droughts like the 1930s Dust Bowl and the current drought in the Southwest have historically lasted maybe a decade or a little less,\" said Ben Cook, climate scientist at NASA's Goddard Institute for Space Studies and the Lamont-Doherty Earth Observatory at Columbia University in New York City, and lead author of the study. \"What these results are saying is we're going to get a drought similar to those events, but it is probably going to last at least 30 to 35 years.\" || ",

Analysis of current greenhouse gas emission trends indicate that the Southwest and Central Plains have an 80% likelihood of megadroughts between the years 2050 and 2099.2. This is the first study to compare future drought projections directly to drought records from the last 1000 years.TAG: The 1930’s Dust Bowl only lasted a decade. These new results indicate future droughts may last at least 30 to 35 years. || WC_Drought-1920-MASTER_iPad_1920x0180_print.jpg (1024x576) [75.1 KB] || WC_Drought-1920-MASTER_iPad_1920x018000449_print.jpg (1024x576) [69.5 KB] || WC_Drought-1920-MASTER_iPad_1920x0180_searchweb.png (320x180) [49.3 KB] || WC_Drought-1920-MASTER_iPad_1920x0180_web.png (320x180) [49.3 KB] || WC_Drought-1920-MASTER_iPad_1920x0180_thm.png (80x40) [4.3 KB] || WC_Drought-1920-MASTER_NBC_Today.mov (1920x1080) [40.0 MB] || WC_Drought-1920-MASTER_WEA_CEN.wmv (1280x720) [4.3 MB] || Drought_WC.avi (1280x720) [5.5 MB] || WC_Drought-1920-MASTER_baron.mp4 (1920x1080) [12.1 MB] || WC_Drought-1920-MASTER_iPad_960x540.m4v (960x540) [12.6 MB] || WC_Drought-1920-MASTER_iPad_1280x720.m4v (1280x720) [20.2 MB] || WC_Drought-1920-MASTER_iPad_1920x0180.m4v (1920x1080) [40.0 MB] || WC_Drought-1920-MASTER_iPad_1920x0180.webm (1920x1080) [1.7 MB] || WC_Drought-1920-MASTER_1920x1080.mov (1920x1080) [255.6 MB] || WC_Drought-1920-MASTER_1280x720.mov (1280x720) [313.7 MB] || WC_Drought-1920-MASTER_prores.mov (1920x1080) [257.3 MB] || ",

            "description": "Normalized Difference Vegetation Index (NDVI) maps allow comparisons of the spatial and temporal variability in the amount and condition of vegetation. The time series satellite derived NDVI was used to monitor and analyze changes in vegetation patterns in the major wheat production domain area in Australia. The NDVI comparison was done during the growing season, April through November, for 2002, 2005, and 2006 and it found that significant differences in vegetation growth production. These data and utilities are fundamental for crop yield forecasts and can serve as an early warning system for regions suffering from crop loss and food shortages. Wheat is Australia's most important crop, with a seasonal gross value approaching 3 billion Australian dollars. Australia contributes between and 8 and 15% of world's wheat trade, making it the fourth largest exporter after the United States, Canada and the European Union. Severe drought in Australia not only decimating crops, but it also curtails exports and causes major price and trade impacts on global markets. In 2006, wheat exports dropped by a third from the year before which caused worldwide prices to soar to the highest levels in a decade. || ",
