ASTER Validation
The Advanced Spaceborne Thermal Emission Reflectance Radiometer will acquire data in 14 spectral channels located in the visible near infrared, short wave infrared and thermal infrared portions of the spectrum. These data will be used to produce a set of standard products which can be easily used by the science community. They include surface temperature, emissivity, reflectance and elevation. The algorithms used to derive the standard products are being developed by the ASTER science team. The algorithms are being validated pre-launch using airborne simulator data as surrogates and will be validated post-launch with ASTER data. This site provides access to some of the documentation that describes these activities as well as some of the ongoing experiments. Users interested in the validation activites of other instruments involved in the Earth Observing System should check out the Related Sites page.
