STACCATO: Influence of stratosphere-troposphere exchange in a changing climate on atmospheric transport and oxidation capacity.
Abstract
Within STACCATO a new three-dimensional Lagrangian perspective of stratosphere - troposphere exchange (STE) will be developed, focussing on "deep" exchange events. The mixing of stratospheric and tropospheric air will be investigated in detail. The relative impact of STE processes on factors controlling the oxidation capacity of the atmosphere will be studied as well as the variability and possible trends of STE during the past decades. STE under scenarios of climate change in future times will be investigated. Seven methods and models used to calculate STE will be intercompared and measurements will be performed in an extended network, suitable to validate the STACCATO models and to estimate the strength of STE and its impact on tropospheric chemistry.
