[ACG36-P03] Influence of the aerosol under the cloud layer on calculation of the shortwave radiation flux in China from Himawari-8/AHI satellite measurement
Keywords:Himawari-8/AHI satellite measurement, Radiative flux
To quantitatively investigate the influence of the heavy aerosol in retrieval of the cloud properties, the RSTAR radiative transfer model is employed to simulate the retrieval error of the cloud parameters caused by aerosols in the boundary layer. The results indicate that when the aerosol optical thickness (AOT) is 0.1, the error of the surface shortwave radiation is small; whereas with the increasing AOT, the error of the shortwave radiation increases obviously. When AOT is 1.2, the relative error reaches 18.38%. For the heavily-polluted areas of North China, it is important to investigate the influence of aerosol on the retrieval of the cloud parameters and solar shortwave radiation in cloudy conditions, which is critical to the assessment of the energy budget in North China suffered from heavy aerosols below the cloud layer.
