abstract = {The chemistry climate model ECHAM-HAMMOZ contains a
detailed representation of tropospheric and stratospheric
reactive chemistry and state-of-the-art parametrisations of
aerorols using either a modal scheme (M7) or a bin scheme
(SALSA). This article describes and evaluates the model
version ECHAM6.3-HAM2.3-MOZ1.0 with a focus on the
tropospheric gas-phase chemistry. A ten-year model
simulation was performed to test the stability of the model
and provide data for its evaluation. The comparison to
observations concentrates on the year 2008 and includes
total column observations of ozone (O3) and carbon monoxide
(CO) from Infrared Atmospheric Sounding Interferometer
(IASI) and Ozone Monitoring Instrument (OMI), Microwave Limb
Sounder (MLS) observations of temperature, nitric acid
(HNO3), chlorine monoxide (ClO), and O3 for the evaluation
of polar stratospheric processes, an ozone sonde
climatology, surface ozone observations from the
Tropospheric Ozone Assessment Report (TOAR) database, and
surface CO data from the Global Atmosphere Watch network.
Global budgets of ozone, hydroxide (OH), nitrogen oxides
(NOx), aerosols, clouds, and radiation are analyzed and
compared to the literature. ECHAM-HAMMOZ performs well in
many aspects. However, in the base simulation, lightning NOx
emissions are very low, and the impact of the heterogeneous
reaction of HNO3 on dust and seasalt aerosol is too strong.
Sensitivity simulations with increased lightning NOx or
modified heterogeneous chemistry deteriorate the comparison
with observations and yield excessively large ozone budget
terms and too much OH. We hypothesize that this is an impact
of potential issues with tropical convection in the ECHAM
model.},
