WMS ORNL DAAC TDS The ORNL DAAC offers Earth science data for global change research and Earth systems studies. Sponsored by NASA, the archive includes field data, remote-sensing data, imagery, and the results of ecosystems modeling. The ORNL DAAC archives regional and global data about climate , environmental processes, nutrient cycles, stream and river discharge, soil properties, canopy chemistry, net primary productivity, land use change, and vegetation. Such data are vital to understanding and predicting how Earth systems function. The data can be used to validate remotely sensed information, as well as to improve and validate the output of ecosystem models. earth science data global change data earth systems ecosystems modeling environmental biosphere remote sensing satellite images climatology terrestrial ecology hydrology meteorology data center ornl daac nasa greenhouse gases net primary production nutrient cycles net primary productivity carbon dioxide co2 carbon cycle trace gases air temperature precipitation heat fluxes energy exchange meteorological data respiration reflectance forests grasslands wetlands river discharge land use change methane ch4 vegetation leaf area index lai solar radiation surface radiation wind direction snow cover soil moisture upper air atmospheric boundary layer wind speed tree height canopy chemistry leaf litter throughfall stream flow streamflow forest cover fire history gas flux surface flux stem growth soil emissions biomass field experiments Amazonia Brazil US Canada North American South American African European Asian CO2 DOE EOS ORNL DAAC NASA NPP npp Contact us ORNL DAAC uso@daac.ornl.gov none none 1 4096 4096 text/xml image/png image/png;mode=32bit image/gif image/jpeg application/vnd.google-earth.kmz image/png text/xml XML ORNL DAAC TDSEPSG:4326 CRS:84 EPSG:41001 EPSG:27700 EPSG:3408 EPSG:3409 EPSG:3857 EPSG:900913 EPSG:32661 EPSG:32761 Spatial and Temporal Characteristics of Rainfall in Africa: Summary Statistics for Temporal Downscaling shp shape parameter of the gamma distribution shape parameter of the gamma distribution -20.0 55.0 -40.0 40.0 2012-01-31T00:00:00.000Z,2012-02-29T00:00:00.000Z,2012-03-31T00:00:00.000Z,2012-04-30T00:00:00.000Z,2012-05-31T00:00:00.000Z,2012-06-30T00:00:00.000Z,2012-07-31T00:00:00.000Z,2012-08-31T00:00:00.000Z,2012-09-30T00:00:00.000Z,2012-10-31T00:00:00.000Z,2012-11-30T00:00:00.000Z,2012-12-31T00:00:00.000Z
