Oxygen absorption band
WebThe detailed spectral absorptances by atmospheric slant paths in the oxygen “A” band have been calculated, using parameters deduced from very high- and medium-resolution spectra and from available data. Special attention is given to the potential use of satellite measurements of sunlight reflected from clouds to determine their heights. WebMar 25, 2016 · The oxygen bands are obvious choices to quantify airmass since the mixing ratio of oxygen is fixed over the full range of atmospheric conditions. The OCO-2 mission …
