AbstractThe proposed work investigates the feasibility of designing and building a high resolution spectroradiometer and integrating it with the NASA-owned Thermal Infrared Multispectral Scanner (TIMS). A limiting factor in the analysis of airborne multispectral thermal infrared imagery, such as from TIMS, is the effects of the atmosphere (between the sensor and scene) on the data. Through a combination of atmospheric attenuation, re-emission, scattering and sky reflectance the purity of the spectra collected by such sensors is degraded. One approach to correcting these factors is to fly a high resolution (1-4 wavenumber) spectroradiometer along with TIMS. If the data from the two systems are co-registered, then these atmospheric effects can be partly or wholly characterized and then corrected.
