The ORNL DAAC is pleased to announce the release of model input driver data compiled specifically for the North American Carbon Program (NACP) Multi-Scale Synthesis and Terrestrial Model Intercomparison Project (MsTMIP).
NACP MsTMIP: Global and North American Driver Data for Multi-Model Intercomparison. Data set prepared by Y. Wei, S. Liu, D. Huntzinger, A.M. Michalak, N. Viovy, W.M. Post, C. Schwalm, K. Schaefer, A.R. Jacobson, C. Lu, H. Tian, D.M. Ricciuto, R.B. Cook, J. Mao, and X. Shi.
This data set provides environmental data that have been standardized and aggregated for use as input to carbon cycle models at global (0.5-degree resolution) and regional (North America at 0.25-degree resolution) scales. The driver data were used by 22 terrestrial biosphere models to run baseline and sensitivity simulations.
The data were compiled from selected sources and integrated into gridded global and regional collections of climatology variables (precipitation, air temperature, air specific humidity, air relative humidity (NA only), pressure, downward longwave radiation, downward shortwave radiation, and wind speed), time-varying atmospheric CO2 concentrations, time-varying nitrogen deposition, biome fraction and type, land-use and land-cover change, C3/C4 grasses fractions, major crop distribution, phenology, multiple soil characteristics, and a land-water mask. The temporal driver data are sufficient for carbon cycle model simulations from 1801 to 2010. The temporal resolution ranges from 3-hourly for climate to monthly for CO2-atm and phenology to annual for N-deposition and landcover.
The North American Carbon Program (NACP) is a multi-disciplinary research program designed to obtain scientific understanding of North America's carbon sources and sinks and of the changes in carbon stocks needed to meet societal concerns, and to provide tools for decision makers. NACP began in 2002 and continues to date. The NACP data collection contains continental carbon budgets, dynamics, processes, and management of the sources and sinks of carbon dioxide, methane, and carbon monoxide in North America and in adjacent ocean regions. This data set was collected as part of the NACP Mid-Continent Intensive (MCI) campaign.
The ORNL DAAC is one of twelve NASA funded Earth Observing System Data and Information System (EOSDIS) Distributed Active Archive Centers (DAACs) and is responsible for archiving and distributing terrestrial ecology and biogeochemical dynamics data.
