- Runoff | NASA Earthdata
Runoff is the measurement of the flow of water into a lake, stream or other waterbody, usually expressed in cubic feet per second The flow is produced by rainfall from storms, precipitation accumulation or transpiration, melting ice or snow, seepage, evaporation, and percolation Determining the runoff potential of an area is important data for water resources and agricultural management
- Global Hydrologic Soil Groups (HYSOGs250m) for Curve Number-Based . . .
This dataset - HYSOGs250m - represents a globally consistent, gridded dataset of hydrologic soil groups (HSGs) with a geographical resolution of 1 480 decimal degrees, corresponding to a projected resolution of approximately 250-m These data were developed to support USDA-based curve-number runoff modeling at regional and continental scales Classification of HSGs was derived from soil
- Glacier Runoff - NASA Earthdata
Glacier runoff is the water that comes from rain falling on or the melting of a glacier Runoff water flows into rivers, lakes, and oceans changing their shape, depth, span, flow rates, chemistry, environment, and more Runoff matters for many reasons For example, many animal and human communities depend on runoff to reliably fill rivers, lakes, and reservoirs for drinking water Too much
- Cattle, Crops, and Coral: Flood Plumes and the Great Barrier Reef
The Fitzroy's waters flush sediment, fertilizers, pesticides, herbicides, and other civilization-borne runoff hundreds of miles into the water off the coast of Australia At the end of the runoff plume, waiting for the sediment and nutrients to settle, are the prismatic corals of the Great Barrier Reef
- Data Catalog | NASA Earthdata
Data previously managed by SEDAC are now available in Earthdata Search Access the latest information and complete data products
- Using Coastal Surface Salinity to Monitor Global Water Cycle Changes
Runoff from land is projected to increase by ~7% 8 which could have a significant influence on the coastal ocean The coastal ocean could therefore be a key place to study the global terrestrial water cycle changes and its impacts on physical and biogeochemical processes
- NASA Satellite Data Show Decrease in Colorado River Basin Aquifers
NLDAS is a system of several land surface models (LSMs), which allow researchers to determine the values of hydrologic variables such as runoff, soil moisture, streamflow, and evaporation LSMs use the input data to calculate the output variables
- Agriculture Production - NASA Earthdata
NASA’s Earth data repositories include datasets that measure land surface reflectance, land temperature, vegetation greenness, and crop extent These measurements are used in models to calculate other agriculture-related factors that cannot be observed directly from a satellite, such as evaporation patterns and water runoff
