Revision of the convective transport module CVTRANS 2.4 in the EMAC atmospheric chemistry–climate model
EMAC atmospheric chemistry–climate model convective transport
2015/8/11
The convective transport module, CVTRANS,
of the ECHAM/MESSy Atmospheric Chemistry (EMAC)
model has been revised to better represent the physical flows
and incorporate recent findings o...
Implications of Lagrangian transport for simulations with a coupled chemistry-climate model
Lagrangian transport simulations coupled chemistry-climate model
2009/8/7
For the first time a purely Lagrangian transport algorithm is applied in a fully coupled chemistry-climate model (CCM). We use the numerically non-diffusive Lagrangian scheme ATTILA instead of the ope...
Past and future simulations of NO2 from a coupled chemistry-climate model in comparison with observations
NO2 coupled chemistry-climate model
2009/3/9
Trends in derived from a 45 year integration of a chemistry-climate model (CCM) run have been compared with ground-based measurements at Lauder (45° S) and Arrival Heights (78° S). Observed trends in ...
Technical Note: A diagnostic for ozone contributions of various NOx emissions in multi-decadal chemistry-climate model simulations
ozone contributions various NOx emissions multi-decadal chemistry-climate model
2009/2/26
Nitrogen oxide (NOx=NO+NO2) emissions from various sources contribute to the ozone budget. The identification of these contributions is important, e.g. for the assessment of emissions from traffic. Th...
Hemispheric ozone variability indices derived from satellite observations and comparison to a coupled chemistry-climate model
Hemispheric ozone satellite observations coupled chemistry-climate model
2009/1/19
Total column ozone is used to trace the dynamics of the lower and middle stratosphere which is governed by planetary waves. In order to analyse the planetary wave activity a Harmonic Analysis is appli...
Nitrogen compounds and ozone in the stratosphere: comparison of MIPAS satellite data with the chemistry climate model ECHAM5/MESSy1
Nitrogen compounds ozone stratosphere MIPAS satellite data ECHAM5/MESSy1
2008/12/24
The chemistry climate model ECHAM5/MESSy1 (E5/M1) in a setup extending from the surface to 80 km with a vertical resolution of about 600 m near the tropopause with nudged tropospheric meteorology allo...
Solar cycle variations of stratospheric ozone and temperature in simulations of a coupled chemistry-climate model
Solar cycle stratospheric ozone coupled chemistry-climate model
2008/12/4
The results from three 45-year simulations of a coupled chemistry climate model are analysed for solar cycle influences on ozone and temperature. The simulations include UV forcing at the top of the a...
The quasi-biennial oscillation (QBO) of zonal wind is a prominent mode of variability in the tropical stratosphere. It affects not only the meridional circulation and temperature over a wide latitude ...
