Infrared Aircraft Spectra Over Desert Terrain 8.5 micro to 16 micro
Abstract:
Spectra in the 8.5-16-micro interval, taken at various altitudes over relatively uniform desert terrain, show attenuation of upwelling radiation by atmospheric gases and haze through the entire spectral interval. Equivalent blackbody temperatures, even in the clearest part of the window, show a drop that could introduce serious errors into remote sensing of surface temperatures. Surface emissivity characteristies are discernible at low altitudes but are somewhat masked by ozone at 10-km altitudes.

IR Spectrum
Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
