An objective of this Assessing Burn Severity project was to form a spectral library of endmembers of the major surface component materials encountered on the wildfires we sampled in western Montana mixed conifer forest, southern California chaparral, and interior Alaska spruce forest. Within each of these three regions, we have further organized the spectral endmembers into functional groups:
- green (photosynthetic) vegetation
- non-photosynthetic vegetation
- soil and/or rock
- char and/or ash spectra
A digital photo of the endmember material, a graph of the endmember spectrum, and a downloadable ASCII file of the actual spectrum is provided. We encourage users to download these endmember spectra for SMA of imagery within these regions, both for burn severity or other applications.
- Green (photosynthetic) Vegetation

- Non-Photosynthetic Vegetation
