Results of an interactively coupled atmospheric chemistry – general circulation model: Comparison with observations

The coupled climate-chemistry model ECHAM4.L39(DLR)/CHEM is presented which enables a simultaneous treatment of meteorology and atmospheric chemistry and their feedbacks. This is the first model which interactively combines a general circulation model with a chemical model, employing most of the important reactions and species necessary to describe the stratospheric and upper tropospheric ozone...

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...

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 ...

Relating Atmospheric Radiation Measurement Observations to General Circulation Model Scales

The principal goal of the Atmospheric Radiation Measurement Program (ARM) is to obtain data that will be useful in improving the parameterization of clouds in General Circulation Models (GCMs). With this goal in mind, an extensive field program has been initiated in Oklahoma to obtain the necessary measurements. The field site consists of a central location where an enormous set of cloud and ra...
