Estimating the carbon fluxes using the CASA model in the southern United States.

摘要

A minute change in human body temperature can get one collapsed permanently. If this is the case with human body, one might wonder what would be the case with Earth. The result is the greenhouse. The main function of the greenhouse gases (GHG's) is to tap energy from the sun and prevent the heat energy escaping to space, thus sustaining life on earth. Because of increased human activity, industrialization, and deforestation, the concentration of the GHG's in the atmosphere has increased, resulting in a temperature rise. Considering the effects of temperature rise, caused by the GHG's, one should know the ways to minimize them. In order to do this, an estimation of the amount of GHG's is important. The CASA model is one such model that estimate the GHG's and also the amount of carbon in the atmosphere by estimating the Net Ecosystem Productivity (NEP) and Net Primary Productivity (NPP).
