Parameters for Ecosystem Modeling

Submitted by ORNL DAAC Staff on 2002-12-19

The ORNL DAAC announces the release of a data set entitled "Literature-Derived Parameters for the BIOME-BGC Terrestrial Ecosystem Model."

The data set contains documented ecosystem parameters for major natural temperate biomes in the United States. The parameters are based on the input requirements for BIOME-BGC, a biogeochemical process-based model. The data are suitable for statistical analysis and can be used in other ecosystem models.

The parameters include the following: turnover and mortality; allocation; carbon to nitrogen ratios (C:N); the percent of plant material in labile, cellulose, and lignin pools; leaf morphology; leaf conductance rates and limitations; canopy water interception and light extinction; and the percent of leaf nitrogen in Rubisco (i.e., ribulose bisphosphate-1,5-carboxylase/oxygenase).
