Two-moment bulk stratiform cloud microphysics in the GFDL AM3 GCM: description, evaluation, and sensitivity tests
Two-moment bulk stratiform cloud microphysics the GFDL AM3 GCM sensitivity tests
2010/9/14
A new stratiform cloud scheme including a two-moment bulk microphysics module, a cloud cover parameterization allowing ice supersaturation, and an ice nucleation parameterization has been implemented ...
Parameter estimation in an atmospheric GCM using the Ensemble Kalman Filter
Parameter estimation atmospheric GCM Ensemble Kalman Filter
2009/11/9
We demonstrate the application of an efficient multivariate probabilistic parameter estimation method to a spectral primitive equation atmospheric GCM. The method, which is based on the Ensemble Kalma...
Preindustrial-to-present-day radiative forcing by tropospheric ozone from improved simulations with the GISS chemistry-climate GCM
Preindustrial-to-present-day radiative forcing tropospheric ozone GISS chemistry-climate GCM
2009/3/11
Improved estimates of the radiative forcing from tropospheric ozone increases since the preindustrial have been calculated with the tropospheric chemistry model used at the Goddard Institute for Space...
Sensitivity studies of oxidative changes in the troposphere in 2100 using the GISS GCM
oxidative changes troposphere GISS GCM
2009/3/11
We examine the relative importance of chemical precursor emissions affecting ozone (O3) and hydroxyl (OH) for the year 2100. Runs were developed from the Comparison of Tropospheric Oxidants (Ox_Comp) ...
Simulating aerosol microphysics with the ECHAM4/MADE GCM – Part II: Results from a first multiannual simulation of the submicrometer aerosol
Simulating aerosol microphysics ECHAM4/MADE GCM multiannual simulation submicrometer aerosol
2009/1/21
First results of a multiannual integration with the new global aerosol model system ECHAM4/MADE are presented. This model system enables simulations of the particle number concentration and size-distr...
Influence of Giant CCN on warm rain processes in the ECHAM5 GCM
Giant CCN warm rain ECHAM5 GCM
2008/11/13
Increased Cloud Condensation Nuclei (CCN) load due to anthropogenic activity might lead to non-precipitating clouds because the cloud drops become smaller (for a constant liquid water content) and, th...
Evaluation of the atmospheric transport in a GCM using radon measurements: sensitivity to cumulus convection parameterization
atmospheric transport GCM cumulus convection parameterization
2008/11/7
The radioactive species radon (222Rn) has long been used as a test tracer for the numerical simulation of large scale transport processes. In this study, radon transport experiments are carried out us...
A GCM study of organic matter in marine aerosol and its potential contribution to cloud drop activation
GCM organic matter marine aerosol potential contribution cloud drop activation
2008/10/29
With the global aerosol-climate model ECHAM5-HAM we investigate the potential influence of organic aerosol originating from the ocean on aerosol mass and chemical composition and the droplet concentra...
