Across the Great Plains of the United States and Canada, devastating drought spread across grasslands and croplands in summer 2006. Poor winter snowfall and a blisteringly earthobservatory.nas a.gov/NaturalHazards /natural_hazards_v2. php3?img_id=13742 hot summer following several years of dry conditions have created a dire situation for many farmers and ranchers across the region. According to a www.nytimes.com/2006 /08/29/us/29drought. html?ex=1157688000&e n=13a216546b7d4243&e i=5070 recent article on the New York Times Website, many people are comparing the conditions to the Dust Bowl of the 1930s. The widespread drought conditions are obvious in this vegetation anomaly image based on data from the Moderate Resolution Imaging Spectroradiometer modis.gsfc.nasa.gov (MODIS) on NASA's terra.nasa.gov Terra satellite. Places where vegetation is healthier or more abundant than average are green, places where vegetation is about the same as average are pale yellow, and places where vegetation is not as healthy or abundant as average are brown. Gray patches show where no data were available, probably because of persistent clouds. One of the most common satellite-based vegetation maps is a scale, or index, of vegetation greenness called the ''NDVI,'' short for This image compares NDVI values from July 28-August 12, 2006, to the average values from 2001-2005. Vegetation was faring worst along the Missouri River through North and South Dakota, but below-average vegetation conditions stretch across parts of Montana, Wyoming, Colorado, northwestern Nebraska, and Minnesota as well. The plains of Canada's Saskatchewan and Manitoba provinces were suffering drought, too. A few small pockets of green in the image reveal where vegetation greenness values observed by MODIS were higher than average: the mountains of north-central Colorado, southeastern Nebraska, and the Red River Valley. The Red River Valley experienced widespread snowfall and heavy rains in the spring of 2006, leading to earthobservatory.nas a.gov/NaturalHazards /natural_hazards_v2. php3?img_id=13500 significant flooding. The early-season moisture may have helped the vegetation in the area withstand the hot summer. According to the August 29, 2006, update from the www.drought.unl.edu/ dm/monitor.html U.S. Drought Monitor, most of the Northern Great Plains, as well as much of Oklahoma and Texas, was still in the midst of drought, with many areas falling into the highest category: exceptional drought. * www.ncdc.noaa.gov/pa leo/drought/drght_ho me.html North American Drought: A Paleoclimate Perspective from the National Climatic Data Center * earthobservatory.nas a.gov/Newsroom/NewIm ages/images.php3?img _id=16493 Revisitng the Dust Bowl from the Earth Observatory * earthobservatory.nas a.gov/Study/DustBowl / From the Dust Bowl to the Sahel from the Earth Observatory
