Research Abstract

We have newly developed a measuring system of column-averaged mixing ratio of carbon dioxide and methane with an optical spectrum analyzer operated in near infrared region. We made an evaluation of the instrumental parameters such as a resolution in wavelength and sensitivity, and have found that the estimated resolution was achieved to an expected value if we used an optical fiber with a slit at the edge. Next, we developed a program to retrieve a column-averaged mixing ratio from an observed spectrum. Simulation results showed that we can retrieve the mixing ratio within an accuracy of 1% from the spectrum whose signal-to-noise ratio is 500. We had made a comparison between the mixing ratio obtained with our system and a high-resolution FTIR system, and have found that fluctuation of the intensity obtained with our system was estimated to be about 3%, which is not achieved to the expected value. We will improve a mount mechanism of the fiber and slit system to resolve this problem.
