Paper Abstract

Two types of Fourier transform infrared (FTIR) remote sensing systems are designed to do long term monitoring of the earth atmosphere temporally and spatially at Taiwan ground station. One of them is the FTIR coupled with one km long path White cell. It is capable of measuring the trace gases at the surface level with a sensitivity of 1 ppbv. The concentrations of CO, N2O, and CO2 are measured using this surface long path White cell FTIR. The other FTIR system is the FTIR coupled with a telescope tracked to the sun or moon. A sandwich detector of combining InSb and MCT photoconductors is used as the InSb mode, MCT mode. The concentrations of CO and O3 in the upper atmosphere are measured. The concentration of CO is therefore compared between the ground surface level and the troposphere level.
