This map depicts model estimates of annual average direct normal irradiance (DNI) at 10 km resolution based on hourly estimates of radiation over 10 years (2002-2011). The inputs are visible imagery from geostationary satellites, aerosol optical depth, water vapor, and ozone. Units: kWh/m sq. per day, Source: NREL

Units: Dry Tons, Metadata: BT2 Energy Crops 2022 $60/dry ton. These data are derived from the Billion Ton Update produced by Oak Ridge National Laboratory for the Department of Energy Office of Biomass Program.

Units: Tonnes/yr, Metadata: Available crop residues are estimated using total crop production, crop to residue ratio, moisture content, and the amount of residue left on the field for soil protection, grazing and other agricultural activities. Source: USDA, National Agricultural Statistics Service; 5 year average: 2004-2008 data. For more information on data development, please refer to (http://www.nrel.gov/docs/fy06osti/39181.pdf). Although the document contains the methodology for the development of an older assessment, the information is applicable to this assessment as well. The difference is only in the data’s time period.

Units:tonnes/yr, metadata:The following animal types were included in this analysis: diary cows, beef cows, hogs and pigs, sheep, chickens and layers, broilers, and turkey. The methane emissions were calculated by animal type and manure management system at a county level. Source: USDA, National Agricultural Statistics Service, 2002 data.
