Development and evaluation of the unified troposphericestratospheric chemistry extension (UCX) for the global chemistry-transport model GEOS-Chem
Global chemistry-transport models (CTMs) typically use simplified parameterizations or relaxation to climatology to estimate the chemical behavior of the stratosphere only in the context of its impact on tropospheric chemistry. This limits investigation of stratospheric chemistry and interactions between tropospheric and stratospheric chemistry-transport processes.We incorporate stratospheric c...
متن کاملDevelopment of a grid-independent GEOS-chem chemical transport model as an atmospheric chemistry module for Earth System Models
6 The GEOS-Chem global chemical transport model (CTM), used by a large atmospheric chemistry 7 research community, has been re-engineered to also serve as an atmospheric chemistry module for Earth 8 System Models (ESMs). This was done using an Earth System Modeling Framework (ESMF) interface 9 that operates independently of the GEOS-Chem scientific code, permitting the exact same GEOS-Chem 10 c...
متن کاملThe global chemistry transport model TM5: description and evaluation of the tropospheric chemistry version 3.0
We present a comprehensive description and benchmark evaluation of the tropospheric chemistry version of the global chemistry transport model TM5 (Tracer Model 5, version TM5-chem-v3.0). A full description is given concerning the photochemical mechanism, the interaction with aerosol, the treatment of the stratosphere, the wet and dry deposition parameterizations, and the applied emissions. We e...
متن کاملSensitivity of chemistry-transport model simulations to the duration of chemical and transport operators: a case study with GEOS-Chem v10-01
Chemistry-transport models involve considerable computational expense. Fine temporal resolution offers accuracy at the expense of computation time. Assessment is needed of the sensitivity of simulation accuracy to the duration of chemical and transport operators. We conduct a series of simulations with the GEOS-Chem chemistry-transport model at different temporal and spatial resolutions to exam...
متن کاملAtmospheric chemistry in volcanic plumes.
Recent field observations have shown that the atmospheric plumes of quiescently degassing volcanoes are chemically very active, pointing to the role of chemical cycles involving halogen species and heterogeneous reactions on aerosol particles that have previously been unexplored for this type of volcanic plumes. Key features of these measurements can be reproduced by numerical models such as th...
