Carbon Data
Progress in modeling the global carbon cycle was previously inhibited by the lack of adequate observational data for model parameterization and validation, such as net primary productivity (NPP) and its individual components from field measurements. To address this problem, the Global Primary Production Data Initiative (GPPDI) was set up as a Focus 1 activity of the IGBP Data and Information System, a coordinated international program to improve worldwide estimates of terrestrial NPP for parameterization, calibration, and validation of NPP models at various scales.
The NPP Database contains documented field measurements of NPP for global terrestrial sites compiled from published literature and other extant data sources. The NPP Database contains biomass dynamics, climate, and site-characteristics data georeferenced to each intensive site. A major goal of the data compilation is to use consistent and standard well-documented methods to estimate NPP from the field data.
