China experienced heavy aerosol pollution in recent years. The aerosol
pollution might change surface solar radiation and impact the land
carbon cycle in China. Therefore, we combined the MODIS Atmosphere and
Land products with process-based model to evaluate the sensitivity of
GPP to AOD in different spectral bands under all-sky and cloudless
conditions and the effects of current aerosol loadings on GPP at site
level. Our results indicated that the radiative effects of aerosols on
GPP varied with the vegetation type, which is consistent with other
studies. We also found that the radiative effects of aerosols on GPP
varied with the spectral bands. Cloud restrains the effects of aerosols
on growth of plants. Current aerosol loadings fertilized the growth in
two forest growth and slightly impede the growth of grass. The results
in this paper could be help to fully understand the influences of
aerosol on land carbon cycle.
