The old radiation scheme in IAP9L-AGCM is replaced by a new one from the CCM3/NCAR codes.And the effects of such modification are evaluated in detail.It shows that there are many improvements in the simulated radiation fields from the new version of IAP9L-AGCM,especially some net radiation fields at the surface.As a result,there is a prevalent enhancement of the atmospheric temperature in the new version.Other fields,such as sea level pressure,surface air temperature,geopotential height,wind field,precipitation,specific humidity and so on,show some corresponding changes,though the magnitudes are not large.The evaluation results put forward the requirement of a further improvement of the IAP9L-AGCM.
