| Abstract: | The method for estimating planetary albedo and outgoing longwave radiation at the top of atmosphere by using of NOAA11 - AVHRR data was decided. The AVHRR data set obtained from 10 times NOAA 11 satellite just overpassing the HEIFE area in March to May, 1991 were analysed. The results show that AVHRR data is available for studying the influence of atmospheric dust on the radiative energy budget in the earth-atmosphere systerm. The reflectances of AVHRR visible and near infrared channels, and the brightness temperature difference between the channel 3 and 4 are sensible to the atmospheric dust: the backscatter and planetary albedo of the earth-atmosphere systerm are increased with the increasing atmospheric turbidity, but the outgoing longwave radiation at the top of atmosphere is decreased, which seems depended on the surface temperature. |
