\rAugusto Getirana, a hydrologist at NASA's Goddard Space Flight Center, in Greenbelt, Maryland, analyzed the amount of water stored in aquifers and rivers across Brazil from 2002 to 2015, interested in understanding the depth of the current drought.
\rA new data visualization of 13 years of GRACE data shows the distribution of water across Brazil. Blues indicate increases in water, mostly occurring in the western regions of Brazil in the rainforest. Meanwhile red and orange shows where water stores have declined, occurring mainly in the north and southeast. At the beginning of the data collection, in 2002, Brazil was just coming out of a drought that began in 2000. A wet period followed until 2012 when dry conditions set in again due to a lack of precipitation and higher than usual temperatures, according to supplemental data.
\rSoutheastern Brazil was hardest hit by drought conditions, said Getirana. To make matters worse, Brazil relies on rivers that feed into reservoirs and dams that generate about 75 percent of the electrical power for the country. By September 2014, for example, the Cantareira reservoir system that provides water for 8.8 million people in São Paulo's metro region reported that it was filled to 10.7 percent of its total capacity, a situation that has led to major water rationing.

A new NASA study estimates that the region has lost an average of 15 trillion gallons of water per year from 2012 to 2015. Eastern Brazil as a whole has lost on average 28 trillion gallons of water per year over the same time period.Augusto Getirana, a hydrologist at NASA's Goddard Space Flight Center, in Greenbelt, Maryland, analyzed the amount of water stored in aquifers and rivers across Brazil from 2002 to 2015, interested in understanding the depth of the current drought.A new data visualization of 13 years of GRACE data shows the distribution of water across Brazil. Blues indicate increases in water, mostly occurring in the western regions of Brazil in the rainforest. Meanwhile red and orange shows where water stores have declined, occurring mainly in the north and southeast. At the beginning of the data collection, in 2002, Brazil was just coming out of a drought that began in 2000. A wet period followed until 2012 when dry conditions set in again due to a lack of precipitation and higher than usual temperatures, according to supplemental data.Southeastern Brazil was hardest hit by drought conditions, said Getirana. To make matters worse, Brazil relies on rivers that feed into reservoirs and dams that generate about 75 percent of the electrical power for the country. By September 2014, for example, the Cantareira reservoir system that provides water for 8.8 million people in São Paulo's metro region reported that it was filled to 10.7 percent of its total capacity, a situation that has led to major water rationing.Research: Extreme water deficit in Brazil detected from space.Journal: Hydrometeorology, October 27, 2015.Link to paper: http://journals.ametsoc.org/doi/abs/10.1175/JHM-D-15-0096.1Here is the YouTube video.Additional footage from: Itaipu Binacional Files. || ", "release_date": "2015-10-28T11:00:00-04:00", "update_date": "2023-05-03T13:49:11.083303-04:00", "main_image": { "id": 438310, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a012000/a012036/Brazil-Drought-INST_print.jpg", "filename": "Brazil-Drought-INST_print.jpg", "media_type": "Image", "alt_text": "For complete transcript, click here.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [], "products": [], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
