Interactive comment on “Simulating organic species with the global atmospheric chemistry general circulation model ECHAM5/MESSy1: a comparison of model results with observations” by A. Pozzer et al

The paper describes the evaluation of organic species concentrations as simulated by an atmospheric chemistry general circulation model. Overall it is a nice paper that deserves publication in ACP although there is a need for more detailed discussions at some places as further discussed in the following. Also in some cases, the rationales for choosing (or omitting) some sensitivity simulations ...

Simulating organic species with the global atmospheric chemistry general circulation model ECHAM5/MESSy1: a comparison of model results with observations

The atmospheric-chemistry general circulation model ECHAM5/MESSy1 is evaluated with observations of different organic ozone precursors. This study continues a prior analysis which focused primarily on the representation of atmospheric dynamics and ozone. We use the results of the same reference simulation and apply a statistical analysis using data from numerous field campaigns. The results ser...

Global cloud and precipitation chemistry and wet deposition: tropospheric model simulations with ECHAM5/MESSy1

The representation of cloud and precipitation chemistry and subsequent wet deposition of trace constituents in global atmospheric chemistry models is associated with large uncertainties. To improve the simulated trace gas distributions we apply the new submodel SCAV, which includes detailed cloud and precipitation chemistry and present results of the atmospheric chemistry general circulation mo...

Organic species simulated with ECHAM5/MESSy1

Interactive comment on “Improved simulation of isoprene oxidation chemistry with the ECHAM5/MESSy chemistry-climate model: lessons from the GABRIEL airborne field campaign” by T. M. Butler et al

Atmospheric boundary layer (ABL) dynamics exert a large influence on atmospheric chemistry, but it is sometimes relegated to a secondary role in the analysis of the behaviour of reactive species within the ABL. Since Butler et al (2008) used the word lessons in their article’s title; I would like to add some extra ones motivated after reading their paper. The first one is related to the vertica...
