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...
Assessment of parameters describing representativeness of air quality in-situ measurement sites
parameters air quality in-situ measurement sites
2010/8/12
The atmospheric layer closest to the ground is strongly influenced by variable surface fluxes (emissions, surface deposition) and can therefore be very heterogeneous. In order to perform air quality m...
