NASA, in cooperation with several other agencies, has been studying the characteristics
of wildland fires with particular emphasis on understanding nutrient transport mechanisms.
These studies have shown that multispectral data, especially in the thermal infrared
region, provides valuable information on fire characteristics.. Existing instruments
provide thermal infrared data in only a few broad bands of the spectrum and it ispredicted
that better measurements could be obtained using many more bands and higher spectral
resolution. It may be possible to design a new spectrometer for an existing NASA
airborne multispectral scanner to acquire the desired high spectral resolution data.
The proposed research will investigate the feasibility of designing and building
a multispectral thermal infrared spectrometer. The effort will involve the analysis
of alternative spectrometer designs which might be implemented using the existing
scaner primary optics and signal processing electronics. Each alternative design
will be evaluated with respect to compatibility with the existing system, number
of spectral bands that can be obtained, and the probable performance characteristics
of the resulting instrument.
Successful completion of the proposed research will result in the design of an instrument
for airborne measurement of wildland fire characteristics on a local and regional
