Neighbouring effect of land use changes and fire emissions on atmospheric CO and CH over suburban region of India (Shadnagar).

The present study investigated the effects of land use/land cover (LU/LC) changes on atmospheric carbon dioxide (CO) and methane (CH) concentrations over the sub-urban region of India (Shadnagar) using continuous decadal CO and CHin-situ data measured by the greenhouse gas analyser (GGA). Data was collected from 2013 to 2022 at a 1 Hz frequency. Analysis of the current study indicates that during pre-monsoon, the seasonal maximum of CO was 409.

Seasonal and annual variations of CO and CH at Shadnagar, a semi-urban site.

Carbon dioxide (CO) and methane (CH) are the most important greenhouse gases (GHGs) due to their significant role in anthropogenic global climate change. The spatio-temporal variations of their concentration are characterized by the terrestrial biosphere, seasonal weather patterns and anthropogenic emissions. Hence, to understand the variability in regional surface GHG fluxes, high precision GHGs measurements were initiated by the National Remote Sensing Center (NRSC) of India.
