Impact of preindustrial to present‐day changes in short‐lived pollutant emissions on atmospheric composition and climate forcing Open
We describe and evaluate atmospheric chemistry in the newly developed Geophysical Fluid Dynamics Laboratory chemistry‐climate model (GFDL AM3) and apply it to investigate the net impact of preindustrial (PI) to present (PD) changes in shor…
Evaluation of ACCMIP outgoing longwave radiation from tropospheric ozone using TES satellite observations Open
We use simultaneous observations of tropospheric ozone and outgoing longwave radiation (OLR) sensitivity to tropospheric ozone from the Tropospheric Emission Spectrometer (TES) to evaluate model tropospheric ozone and its effect on OLR sim…
Sensitivity of outgoing longwave radiative flux to the global vertical distribution of ozone characterized by instantaneous radiative kernels from Aura-TES Open
[1] We calculate the sensitivity of outgoing longwave radiation (OLR) to the global vertical distribution of tropospheric ozone using ozone profile estimates from Aura Tropospheric Emission Spectrometer (Aura-TES) along with the partial de…
The impact of orbital sampling, monthly averaging and vertical resolution on climate chemistry model evaluation with satellite observations Open
Ensemble climate model simulations used for the Intergovernmental Panel on Climate Change (IPCC) assessments have become important tools for exploring the response of the Earth System to changes in anthropogenic and natural forcings. The s…
Global multi-year O <sub>3</sub> -CO correlation patterns from models and TES satellite observations Open
The correlation between measured tropospheric ozone (O3) and carbon monoxide (CO) has been used extensively in tropospheric chemistry studies to explore the photochemical characteristics of different regions and to evaluate the ability of …

The vertical distribution of ozone instantaneous radiative forcing from satellite and chemistry climate models Open
We evaluate the instantaneous radiative forcing (IRF) of tropospheric ozone predicted by four state-of-the-art global chemistry climate models (AM2-Chem, CAM-Chem, ECHAM5-MOZ, and GISS-PUCCINI) against ozone distribution observed from the …
Sensitivity of tracer transport to model resolution, prescribed meteorology and tracer lifetime in the general circulation model ECHAM5 Open
Atmospheric transport of traces gases and aerosols plays an important role in the distribution of air pollutants and radiatively active compounds. For model simulations of chemistry-climate interactions it is important to know how the tran…
Sensitivity of tracer transport to model resolution, forcing data and tracer lifetime in the general circulation model ECHAM5 Open
The transport of tracers in the general circulation model ECHAM5 is analysed using 9 independent idealized tracers with constant lifetimes released in different altitude regions of the atmosphere. The source regions were split into the tro…
The influence of African air pollution on regional and global tropospheric ozone Open
We investigate the influence of African biomass burning, biogenic, lightning and anthropogenic emissions on the tropospheric ozone over Africa and globally using a coupled global chemistry climate model. Our model studies indicate that sur…

The influence of African air pollution on regional and global tropospheric chemistry Open
We investigate the relative importance of African biomass burning, biogenic volatile organic compounds (VOC), lightning and anthropogenic emissions to the tropospheric ozone budget over Africa and globally using a coupled global chemistry …
