| Outline of Final Research Achievements |
We have developed a method for visualizing the spatial distribution of nitrogen dioxide (NO2) in the atmosphere by analyzing hyperspectral images of skylight obtained with a hyperspectral camera (image size: 640 x 480) which can divide the visible light into ~1000 spectral channels. Using this method, we have observed the 360-degree view of skylight from the rooftop of a building on the campus of Chiba University. It was found that NO2 concentration was relatively higher in the directions of urban areas with heavy traffic. Also, we have observed the atmosphere on and around the runway, and found the increase in NO2 concentration during the takeoff, followed by dissipation by winds.
