Abstract:

The CASA2 Biosphere Model is a spatially-resolved modeling environment designed to extrapolate ecophysiological and biogeochemical principles to the global scale. Its main advantage is its reliance on both satellite data and a mechanistic plant and soil carbon model to model the flow of carbon through terrestrial ecosystems. A number of interesting applications of the model have been developed recently with the aim of exploring, among other things:

CASA calculates the seasonal flow of carbon between the atmosphere and the terrestrial biosphere on a number of different time steps and a multitude of spatial resolutions. The main strength of the CASA model is its ability to use remote sensing data to calculate net primary production (NPP) and carbon turnover mechanistically through a CENTURY-like plant and soil carbon cycling model
