URBAN MICROCLIMATE IMPROVEMENT USING ENVI-MET CLIMATE MODEL
Urban Microclimate simulation vegetation scenarios
2018/11/9
The aim of this paper is the modelling of urban microclimate, based on the limits imposed by the complexity of the three-dimensional space of cities. To this purpose, different Bioclimatic Scenarios w...

Aerosol nucleation and its role for clouds and Earth's radiative forcing in the aerosol-climate model ECHAM5-HAM
Aerosol nucleation clouds and Earth's radiative forcing the aerosol-climate model ECHAM5-HAM
2010/11/30
Nucleation from the gas phase is an important source of aerosol particles in the Earth's atmosphere, contributing to the number of cloud condensation nuclei, which form cloud droplets. We have impleme...
Estimation of ECHAM5 climate model closure parameters with adaptive MCMC
ECHAM5 climate model closure parameters adaptive MCMC
2010/11/3
Climate models contain closure parameters to which the model climate is sensitive. These parameters appear in physical parameterization schemes where some unresolved variables are expressed by predefi...
Evaluation of simulated aerosol properties with the aerosol-climate model ECHAM5-HAM using observations from the IMPACT field campaign

2010/8/25
In May 2008, the measurement campaign IMPACT for observation of atmospheric aerosol and cloud properties was conducted in Cabauw, The Netherlands. With a nudged version of the coupled aerosol-climate ...
Stratospheric water vapour and high climate sensitivity in a version of the HadSM3 climate model
Stratospheric water vapour high climate sensitivity the HadSM3 climate model
2010/8/16
It has been shown previously that one member of the Met Office Hadley Centre single-parameter perturbed physics ensemble – the so-called "low entrainment parameter" member – has a much higher climate ...
A comparison of ship and satellite measurements of cloud properties with global climate model simulations in the southeast Pacific stratus deck

2010/8/16
Here, liquid water path (LWP), cloud fraction, cloud top height, and cloud base height retrieved by a suite of A-train satellite instruments (the CPR aboard CloudSat, CALIOP aboard CALIPSO, and MODIS ...
Comparison of a global-climate model to a cloud-system resolving model for the long-term response of thin stratocumulus clouds to preindustrial and present-day aerosol conditions
a global-climate model a cloud-system resolving model thin stratocumulus clouds present-day aerosol conditions
2010/8/16
The response of a case of thin, warm marine-boundary-layer (MBL) clouds to preindustrial (PI) and present-day (PD) conditions is simulated by a cloud-system resolving model (CSRM). Here, both the aero...
Geoengineering by stratospheric SO2 injection: results from the Met Office HadGEM2 climate model and comparison with the Goddard Institute for Space Studies ModelE
stratospheric SO2 injection the Met Office HadGEM2 climate model the Goddard Institute Space Studies ModelE
2010/8/16
We examine the response of the Met Office Hadley Centre's HadGEM2-AO climate model to simulated geoengineering by continuous injection of SO2 into the lower stratosphere, and compare the results with ...
Cirrus clouds in a global climate model with a statistical cirrus cloud scheme
Cirrus clouds a global climate model a statistical cirrus cloud scheme
2010/8/13
A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented in a coupled aerosol and atmospheric circulation model to better represent both subgrid-scale sup...
Quantitative assessment of Southern Hemisphere ozone in chemistry-climate model simulations
Quantitative assessment Southern Hemisphere ozone chemistry-climate model
2010/2/21
Stratospheric ozone recovery in the Southern Hemisphere is expected to drive pronounced trends in atmospheric temperature and circulation from the stratosphere to the troposphere in the 21st century; ...
Investigating the impact of Lake Agassiz drainage routes on the 8.2 ka cold event with a climate model
Lake Agassiz drainage routes 8.2 ka cold event climate model
2009/12/3
The 8.2 ka event is the most prominent abrupt climate change in the Holocene and is often believed to result from catastrophic drainage of proglacial lakes Agassiz and Ojibway (LAO) that routed throug...
