The impact of MM5 and WRF meteorology over complex terrain on CHIMERE model calculations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2009
The objective of this study is to evaluate the impact of meteorological input data on calculated gas and aerosol concentrations. We use two different meteorological models (MM5 and WRF) together with the chemistry transport model CHIMERE. We focus on the

2-way coupling the hydrological land surface model PROMET with the regional climate model MM5 [PDF]

open access: yesHydrology and Earth System Sciences, 2013
Most land surface hydrological models (LSHMs) consider land surface processes (e.g. soil–plant–atmosphere interactions, lateral water flows, snow and ice) in a spatially detailed manner.

Comparison of Urban Canopy Schemes and Surface Layer Schemes in the Simulation of a Heatwave in the Xiongan New Area

open access: yesAtmosphere, 2022
Due to rapid growth and expansion, Xiongan New Area is at risk for heatwaves in the present and future induced by the urban heat island effect. Based on eight combined schemes, including two common WRF surface layer schemes (MM5 and Eta) and urban canopy
