The solar and infrared radiation over east China in summer troposphere were calculated using the MODTRAN3 model and the satellite TOVS data.Solar heating rate and infrared cooling rate were calculated and analyzed from the 43 samples at 12 stations at different latitudes on sunshine day.It is found from the analyses that in summer troposphere,the solar heating rate decreases with height,and its magnitude and change rate are correlated with latitude,zenith angle and atmospheric state.And meanwhile,the solar heating rate also varies diurnally.The infrared cooling rate reaches the minimum value in middle and upper troposphere,and its magnitude and change rate are correlated with latitude and atmospheric state.Results of this paper were compared with precious conclusions and reality,and it is found that the results realistically reflect the radiation heating state of the summer troposphere over east China,and therefore are reliable.
