The following four figures show the difference in 2 meter height surface air temperature simulated by NCAR LSM coupled to CCM3 compared to the Legates and Willmott climatology. Results are for a 14 year simulation using observed SST's from 1979 to 1992. Initial conditions for this simulation were obtained from a 10-year simulation with climatological SST's. Stippled areas show where the difference between simulated and observed temperatures is more than twice the standard deviation based on the model's 14 year climatology.

The following figures show the difference in 2 meter height surface air temperature and total precipitation simulated by NCAR LSM coupled to CCM3 compared to the Legates and Willmott climatology. Results are for a 14 year simulation using observed SST's from 1979 to 1992. Initial conditions for this simulation were obtained from a 10-year simulation with climatological SST's. Data are averaged for all land points in each geographic region. Simulated data are shown with a solid line. The vertical bars indicate the model's 95% confidence interval for the mean based on the 14 year climatology. Observations are shown with a dashed line.

The following figures show hydrologic fields averaged for all land points in each geographic region. Soil water is the volumetric water content of the first 3 soil layers (to a depth of 70 cm). Snow is depth of snow (liquid water) on the ground. Runoff is total runoff (surface + subsurface drainage). Results are for a 14 year simulation using observed SST's from 1979 to 1992. Initial conditions for this simulation were obtained from a 10-year simulation with climatological SST's. The vertical bars indicate the model's 95% confidence interval for the mean based on the 14 year climatology.

The following figures show CO2 fluxes averaged for all land points in each geographic region. Plant respiration includes both maintenance and growth respiration. Results are for a 14 year simulation using observed SST's from 1979 to 1992. Initial conditions for this simulation were obtained from a 10-year simulation with climatological SST's. The vertical bars indicate the model's 95% confidence interval for the mean based on the 14 year climatology.
