COMPASS: Coupled Models Package of Atmosphere and Surface Schemes

COMPASS is a package of coupled models (under development) to be used in the investigation of the Carbon cycle in large tropical forested environments. COMPASS includes two sub-packages: (1) J.M.HENDRIX, currently under development at the University of Washington, Seattle; and (2) J.S.BACH, currently under development at the Max-Planck-Institute, Hamburg. COMPASS will contribute to existing projects, including CAMREX, ("Carbon in the Amazon River Experiment"), LBA ("Large-Scale Biosphere-Atmosphere Experiment in Amazonia"), and various Southeast Asia projects involving the Mekong River among others.

J.M.HENDRIX represents the surface hydrologic and energy balance (VIC), runoff routing, sub-surface flow, sediment transport, and the transport and transformation of Carbon species. J.M.HENDRIX involves researchers and students in the University of Washington's School of Oceanography's River Systems Research Group and the Department of Civil and Environmental Engineering's Land Surface Hydrology Research Group, as well as researchers from the Department of Earth and Space Sciences' Quaternary Research Center. We collaborate closely with CENA ("Centro de Energia Nuclear na Agricultura") in São Paulo, Brazil; the ICRAF (World Agroforestry Centre), headquartered in Nairobi, Kenia; and scientists from the Mekong River Commission headquartered in Vietnam.

J.S.BACH represents the terrestrial biosphere (BETHY, LPJ, and a phenology scheme), coupled to some of the components of VIC and to the atmospheric-dynamics model ECHAM-5. J.S.BACH is being developed by the Max Planck Institutes for Meteorology (in Hamburg) and for Biogeochemistry (in Jena), Germany.
