Land and atmosphere interact with each other through exchanges of energy and water fluxes at different time scales (Bonan et al., 2003;Seneviratne & Stöckli, 2008). Similar to the oceans, land areas interact with the lower boundary of the atmosphere through exchanges of various fluxes (Bonan, 2013). Contributions of land perturbations to atmospheric processes are termed land-atmosphere feedbacks. They are dynamic in nature and vary in space and time. The variations in feedbacks depend on the characteristics of the land surface properties such as the type of soil, soil moisture content, distribution of vegetation, vegetation health (such as Leaf Area Index), surface albedo, land use land cover and surface roughness, etc. Feedback processes from vegetation to atmosphere are grouped into two categories: biogeophysical and biogeochemical feedbacks. Biogeophysical feedback processes involve surface properties such as land use land cover, surface albedo, surface roughness, vegetation coverage, etc. Biogeochemical feedback involves the chemical
