Multipoint comparison of CO2 concentration distribution maps in the living environment

Focusing on the similarity of CO2 concentration distribution as a basis for regional environmental assessment

Abstract

In this study, we created a CO2 concentration distribution map based on 10 years of collected data from CO2 concentration measurement stations established in the three prefectures of Tokai, which were then corrected based on the global observation values from the Minamitorishima, and a comparison of sites was conducted. As a result, 1) the distribution shape of the CO2 concentration distribution map in summer at each location is similar every year; 2) it was found that this can be confirmed by the confidence interval of frequency of wind speed occurrence in the summer main wind direction.
