Research On Detection Of High-Temperature Co2 With Infrared Spectrum From Space

The spectra have been calculated with Line by Line method for high-temperature CO2 and atmosphere. The characteristic of the wing of atmospheric 4.3 mu m absorption band has been analyzed. The variation of transmittance from different altitudes to space in 2370 to 2390cm(-1) was calculated and analyzed. The radiations of high-temperature CO2 located in different altitudes in the same wave range were compared. According to the variation of atmosphere and the spectral characteristic of hot CO2, the way for choosing band of detection was discussed.
