摘要: Abstract New automated observation systems for use in passenger aircraft to measure atmospheric carbon dioxide (CO2) and other trace species have been developed are described this paper. The Continuous CO2 Measuring Equipment (CME) is composed mainly of a nondispersive infrared analyzer, datalogger, two calibration cylinders situ measurements. Automatic Air Sampling (ASE), on the hand, designed flask sampling; instrument, connected metal bellows pump, made up specially control board can accommodate 12 flasks. CME platform be used conduct high-frequency measurements obtaining detailed spatial over wide area, while ASE, despite limited flight frequency, provide useful distributions not only but also various gas species, as well their isotopic ratios. ASE installed racks forward cargo compartment air bypass intake m...
