Hello,

There are a lot of spectral libraries like ECOSTRESS, ASTER, JHU, JPL, and USGS that are freely and easily accessible.

Recently I am working on spectral analysis of some materials especially pigments, but I could not find any spectral library related to the pigments (e.g. chlorophyll a, b, Pheophytin). does anybody know how can I get access(download) to pigments' spectra?

and, is there any complete database for spectral libraries?

Thanks in advance.
