Carbon-dioxide is one of the most abundant gasses in the
atmosphere. Due to human induced anthropogenic activities, the
amount of CO2 released into the atmosphere has been rising
extensively during the last 150 years. Present investigation was
carried out to assess the carbon dioxide concentration in ambient
air of Tarai region of Uttarakhand. The online monitoring of CO2
concentration from ambient air was carried out with the help of a
Non-dispersive Infra-red (NDIR) gas analyzer at one minute time
interval. Simultaneously, air samples were collected from various
sampling sites starting. The ambient air CO2 concentration at
Pantnagar has shown a large fluctuation that varied in the range of
306 ppmv to 427 ppmv with an average concentration of 350.82 ppmv.
Among different sites of sampling, the highest concentration of
surface air CO2 was found at the vehicular sites followed by
Industrial site. Higher CO2 concentration values were found near
the ground and a decreasing pattern was observed with the increase
in height. In general, CO2 concentrations were higher during winter
and lowest during summer season.
