| Abstract: |
The detailed atmospheric processes responsible for altitude-dependent SP 17 sp O(SO SB 4 sb ) remain an open question at present because global SP 35 sp S(SO SB 4 sb )- SP 17 sp O(SO SB 4 sb ) measurements are limited [[11], [14]]. Given the removal lifetime of sulfate in the free troposphere (>1 week) [[7], [11]] is longer than the time scale of the eastward transport of air masses from the Himalayas to Southwest China through the prevailing westerlies (<1 week) (Fig. Overall, using cosmogenic SP 35 sp S, we have shown that the Himalayas and its extensive downwind areas are more affected by stratospheric air than other regions, and these stratospheric influences are also likely recorded by triple oxygen isotopes in atmospheric sulfates. Downward transport of stratospheric air significantly modifies the chemical and radiation budget of the Earth's atmosphere. [Extracted from the article] |
