Green house gases (GHG) concentration variations over Indian region by in situ measurements
A land-based GHG monitoring station is set-up at Sinhagad (SNG) Pune, situated over a mountainous terrain of a south-western peninsular region of Indian subcontinent. The air-samples collected from this site are analyzed by using Gas Chromatograph instrument established at the IITM Pune. This set-up of Gas Chromatograph strictly follows the World Meteorological Organization (WMO) protocols and standard gases for the calibration taken from NOAA/GMD Boulder, Colorado USA.
This CCCR team was also involved in aircraft based GHG’s observations over India during the year 2014, and 2015. In-situ GHGs monitoring instrument was used on the aircraft platform , which successfully monitored atmospheric CO2, CH4, CO, H2O concentrations vertical and horizontal profiles over the Ganga basin (in 2014), and over Maharashtra and Arabian Sea (in 2015).
