Dataset Abstract:

LBA Model intercomparison project (LBA-MIP) protocol and multi-year forcing data. ALMA-compliant and consistently-filled meteorological observations from selected LBA flux towers, including boundary conditions (site location, biome type, soil type and initial data). The data are for periods between 1999 and 2006, the exact time coverage being determined by site-specific data availability (see Data Characteristics). Driving datasets include: a. air temperature b. specific humidity c. module of wind speed d. downward long wave radiation at the surface e. surface pressure f. precipitation g. shortwave downward radiation at the surface h. CO2 will be set to 375 ppm. These atmospheric drivers are provided at 1 hour time-step as ALMA-compliant NetCDF files (see http://www.lmd.jussieu.fr/~polcher/ALMA/) and as tarred, gzipped ASCII files. Models should use linear interpolation (except for solar radiation, where zenithal angle would be more appropriate) if they are run at shorter than a 1 hour time step.
