Detection of nitric acid and nitric oxides in the terrestrial atmosphere in the middle-infrared spectral region

[摘要] A proposal for combined space andground-based observations of the vertical distributions and the column densitiesof nitric acid and nitric oxide concentrations in the earth's atmosphere isdiscussed. We focus on the aspects that are particular to the idea ofcorrelative measurements: geometrical considerations, simulations of the solarabsorption spectra in the middle-infrared region corresponding to the differentobservational geometries, and the associated retrieval methods. These studiesare done specifically for the Belgian-French experiment MIRAS (MIR InfraredAtmospheric Spectrometer) onboard the Russian Space Station MIR and correlativeground-based FTIR measurements in the Tatra mountains.
