Method and results for optimizing the MOPITT methane bandpass.

摘要: The Measurements of Pollution in the Troposphere (MOPITT) instrument will measure carbon monoxide and total column methane Earth’s atmosphere by means gas-filter correlation radiometry. center, width, and shape bandpass filters used to isolate spectral channels must maximize signal level sensitivity gas interest minimize the interference from other absorbing gases (notably water vapor). I calculated as a function filter center width. A slight shift parameters from MOPITT baseline values increases by 20% decreases vapor 6% its baseline value.
