| Outline of Final Research Achievements |
We tried to develop DOAS method using LED light source in the laboratory to improve the DOAS retrieval algorithms. However, we could not develop the method we have been expected at the beginning. We also developed the mobile MAX-DOAS instrument to improve the DOAS retrieval algorithms. The observations by the mobile MAX-DOAS in Fukuoka, an urban area (on the Fukuoka Urban Expressway) and analysis had been made. With comparisons with the continuous measurement by MAX-DOAS at Fukuoka University, we found that NO2 inhomogeneity is strongly related to the inhomogeneity of NOx sources and to horizontal transport of high concentrations from the city center and low concentrations from the ocean via a land-sea breeze. We estimated NOx emission in Fukuoka using the observation data. We also conducted the variations in NO2 observed by the Aura/OMI satellite sensor by using the mobile MAX-DOAS measurements.
