Abstract

The estimate of ambient carbon dioxide (CO2) concentration has been carried out in Madurai during
2003-2016 by using satellite retrieved dataset. Annual, seasonal and monthly variations of carbon
dioxide are observed in this study. Annual averages of carbon dioxide vary from 375 to 403 ppm.
Maximum carbon dioxide concentration is observed in summer and minimum during the winter. The
strong correlation is observed with wind speed (0.65), planetary boundary layer height (0.51) and
rainfall (-0.78). Multiple linear regression analysis results show that the temperature and wind speed are
statistically significant. In addition, Mann Kendal trend analysis results clearly elucidate that there is a
significantly increasing trend in CO2 in this study area. The increase in carbon dioxide is mainly due to
the increasing anthropogenic sources in and around the study area.
