关 键 词：Summertime Nitrate aerosols in the UTLS over the Tibetan Plateau region
摘 要：Distributions of aerosols in UTLS over the Tibetan Plateau were simulated using the GEOS-Chem *** results show evidence for that the contribution of nitrate is comparable to that of sulfate in UTLS over the Tibetan Plateau region,suggesting that the influence of nitrate cannot be *** understand the contribution of nitrate,differences between model simulations with fully interactive aerosols(CTRL)and without nitrate aerosols(NONIT)are *** extinctions obtained from the baseline simulation are closer to SAGE II satellite measurements,which further illustrates the importance of nitrate in *** possible ways are suggested for the enhancement of nitrate near the *** way is the deep convection resulting in the direct transportation of natural and anthropogenic emissions from boundary layer over the Tibetan *** other way is that the occurrence of high H2O mixing ratio and low temperature near the Tropopause are both conducive to the formation of *** the lowest temperature and the highest humidity near the Tropopause of the year,Asian summer monsoon season becomes the best season for the production of nitrate in UTLS over the Tibetan Plateau.
