Global monitoring of stratospheric halogen compounds from a satellite using gas filter spectroscopy in the solar occultation mode.
We have analyzed the gas filter radiometer approach for long-term monitoring of stratospheric HCl, HF, CH(4), and H2O using solar occultation at selected intervals in the 2-6 microm range. Our analysis shows that this instrument technique is feasible. This conclusion is based on a simulation study in which we evaluated the effect of various experiment errors on retrieval accuracy. The instrument errors used were based on measurements made on a breadboard model gas filter radiometer. The results show that HCl and HF can be measured with an rms error of 10% and CH(4), and H2O with an error of 15% over the 10-30-km range.
