EOIR models material types for:
- Aircraft, missiles, ships, ground vehicles, and satellites
- Earth surface
Aircraft, missiles, ships, ground vehicles, and satellites
You can choose from the following common surface material options:
- Aluminum MLI (multi-layer insulation)
- Black Thermal Control Paint
- Burnished Aluminum
- Gold MLI
- Gray Body (with reflectance that you specify)
- Silver MLI
- Solar Panel
- White Thermal Control Paint
- Custom materials

Earth surface materials
EOIR simulates spectral reflectance for the 17 International Geosphere Biosphere Program (IGBP) Global Land Cover types plus Tundra as type 18. The data utilized to create the SRFs came from the spectral reflectance libraries of the United States Geological Survey and Johns Hopkins University. The various land cover types were created as linear combinations of simpler materials. NASA/TP-1999-209362, Surface Emissivity Maps for Use in Satellite Retrievals of Longwave Radiation (PDF) , provided a general guideline for proceeding.
