Case study of deep STE event of ozone at a low latitude Indian station using simultaneous balloon borne ozonesonde and surface ozone measurements

摘要

Stratosphere Troposphere Exchange (STE) of ozone is an important factor influencing the budget of ozone in the troposphere. It is well established that STE is relatively uncommon at low latitudes. Therefore a case study of deep STE event of ozone at a low latitude tropical coastal site of India is presented in the paper using ozonesonde, satellite and UV photometric ozone analyzer data.
