Short summary
We introduce a strategy for the measurement of CO2 in the stratosphere. We use an orbiting limb sounder to measure both the thermal infrared (TIR) and far-infrared (FIR) atmospheric emissions. The rotational transitions of O2 in the FIR are exploited to derive the temperature and pressure fields that are needed to retrieve the CO2 from its spectrum in the TIR. The proposed experiment can determine two-dimensional distributions of the CO2 with precision of 1 ppm at altitudes between 10 and 50 km.
