The Biogeochemistry Working Group for the National Center for Atmospheric Research (NCAR) Community
Climate System Model (CCSM) has initiated an intercomparison of terrestrial biosphere models running within
the CCSM framework. Called the CCSM Carbon-Land Model Intercomparison Project (C-LAMP), its purpose
is to allow the U.S. scientific community to evaluate the performance of biogeochemical cycling models within
CCSM and to identify the most important processes for inclusion in a biosphere model participating in
simulations supporting the IPCC Fifth Assessment Report (AR5). Three terrestrial biogeochemistry modules
coupled to CCSM---CLM3-CASA', CLM3-CN, and LSX-IBIS---will be evaluated following a set of carefully
crafted experiments that build upon the C4MIP
Phase 1 protocol. In Experiment 1, the models will be
forced with an improved NCAR/NCAR reanalysis data set, while in
Experiment 2, the models will be coupled to the Community Atmosphere
Model Version 3 (CAM3) with carbon, water, and energy exchanges over
the
20th century. In order to quickly verify and validate the performance
of these biogeochemistry
models against high quality observations, a set of offline runs for
Fluxnet tower sites have been performed
using observed meteorology. Certain biogeochemical, hydrological,
physiological, and radiation fields have
been saved hourly for intercomparison across models and with high
frequency tower measurements. An
analysis of the offline flux tower runs will be presented along with
preliminary results from the global
experiments run within the CCSM framework. Model results will be made
available by the Program for Climate Model Diagnosis and
Intercomparison (PCMDI) via the Earth System Grid (ESG), and this
presentation will
include an invitation for community participation in the analysis and
evaluation of the model results. C-LAMP
is a subproject of the Computational Climate Science End Station headed
by Dr. Warren Washington, using
computing resources at the National Center for Computational Sciences
(NCCS).
