Abstract:

The solar spectrum in the region from 3150cm to 3950cm was measured at various altitudes from 1.6 km to 31 km using a balloon borne grating spectrometer system. The spectral transmittance of the atmosphere above certain altitudes were deduced from these spectra. The observed spectral transmittance was compared with the theoretical transmittance predicted by Plass considering only CO2 absorption. The comparisons agree well at 15 km. At 30 km. the absorption by H2O approximately equals the absorption by CO2 and the theoretical transmittance estimated from CO2 only differs from the observed. Author
