SPATIALISATION OF RICE GROWTH AND YIELD MODEL USING OPTICAL AND SAR DERIVED BIOPHYSICAL PARAMETERS

The present study reports Column averaged concentration of CO₂ over Shadnagar using Sun's spectra measured by ground based FTIR spectrometer. It is first of its kind in India for measuring columnar and vertical mixing ratios of atmospheric trace gases and other greenhouse gases (GHGs). In the present study, we attempted to retrieve columnar concentration and vertical profile of CO₂ by utilising line-by-line radiative transfer algorithm (LBLRTA) and FASCODE3 inversion model.

This study provides systematic and scientific representation of greenhouse gases (CO₂ and CH₄) and its dynamics at a suburban site of India. It was required to generate reliable, highly precise, and accurate measurements of CO₂ and CH₄ over this part of the world. We made use of high-precision greenhouse gases measurements recorded by LGR-GGA instrument also by complementary data from remote sensing satellites as well as from automatic weather station.
