We began the process of conducting a VEMAP-style modeling exercise in support of North American Carbon Program (NACP). Public-domain versions of the following ecosystem models: BGC, TOPS, CASA, LPJ, SIMCYCLE, BEAMS will be used in the proposed experiment to evaluate uncertainties in estimating carbon fluxes associated with model logic. A standard set of model inputs a la VEMAP is prepared using the Terrestrial observation and Prediction System (TOPS) modeling framework. The input data consists of satellite-derived LAI/FPAR(MODIS, AVHRR), climate data (station networks and gridded data), soils data (ECOCLIMAP), terrain data (SRTM) and other data over the North American region. Upon the projects completion, all inputs and ensemble outputs will be made available via the ecocast website or ftp to the community for further exploration and analysis.
