Water bodies were identified by a spectral analysis of MODIS vegetation indices with the aim to improve existing regional to global mapping products. This data set can be used to enhance the understanding of Earth system processes, and to support global change studies, agricultural planning, and disease prevention. These data provide a gridded (250-m) estimate of the number of years (during 2003-2011) that a pixel was covered by water. The data are presented in a single netCDF (*.nc) file.' description_attribution: http://daac.ornl.gov//HYDROCLIMATOLOGY/guides/Sahel_Water_Bodies.html display_name: Location and Permanency of Water Bodies in the African Sahel Region from 2003-2011 doi: 10.3334/ORNLDAAC/1269 end_time: 2011-12-31T00:00:00 files: [] href: http://52.38.26.42:8080/dataset/nasa-ornldaac-1269.yaml identifier: nasa-ornldaac-1269 instrument_measurements: - dataset_identifier: nasa-ornldaac-1269 display_name: terra/moderate-resolution-imaging-spectroradiometer/nasa-ornldaac-1269 instrument_identifier: moderate-resolution-imaging-spectroradiometer platform_identifier: terra type: instrument_measurement - dataset_identifier: nasa-ornldaac-1269 display_name: aqua/moderate-resolution-imaging-spectroradiometer/nasa-ornldaac-1269 instrument_identifier: moderate-resolution-imaging-spectroradiometer platform_identifier: aqua type: instrument_measurement lat_max: 20 lat_min: 10 lon_max: 40 lon_min: -20 name: Location and Permanency of Water Bodies in the African Sahel Region from 2003-2011 native_id: SAHEL_WATER_BODIES parents: [] processing_level: ~ publication_year: ~ references: [] release_dt: 2015-01-01T00:00:00 scale: ~ scope: ~ spatial_extent: ~ spatial_ref_sys: ~ spatial_res: ~ start_time: 2003-01-01T00:00:00 temporal_extent: ~ temporal_resolution: ~ type: dataset uri: /dataset/nasa-ornldaac-1269 url: http://daac.ornl.gov/cgi-bin/dsviewer.pl?ds_id=1269 variables: ~ version: ~ vertical_extent: ~
