《Table 2 Comparison of results with the original NCEP/NCAR temperature data》
The regression tree model was applied to the corresponding NDVI and DEM data to obtain the monthly temperature data with 1 km spatial resolution.The data were aggregated to the NCEP/NCAR scale(50 km)using a simple averaging method.The averaged data were then subtracted from the NCEP/NCAR data.The residuals were interpolated using the thin spline technique to the 1 km scale,by adding this high-resolution residual to the predicted temperature and precipitation at 1 km resolution,the final downscaled monthly average temperature and monthly total precipitation of China at 1 km resolution being obtained.Figure 3 shows the downscaled temperature for May 2005.
