The diurnal variability of meteorological variables (wind at 10 m and temperature at 2 m, latent and sensible heat fluxes' fields) in the lower surface layer for the ISBA land surface scheme as a function of parameters: roughness, albedo, and anthropogenic heat flux for urban areas was evaluated. The ISBA scheme was modified for urban cells of model domain. The DMI-HIRLAM model (resolution of 1.4 km) was run with modified land use and climate generation files. The specific date - 30 March 2005 - with typical westerly dominating directions of atmospheric transport over Island of Zeeland was analyzed. The diurnal cycle of meteorological variables was analyzed comparing (difference fields at each UTC term) outputs from control run with those where changes of parameters were made. The impacts on the urbanized areas and suburbs of the Copenhagen, Denmark and Malm?, Sweden were evaluated.
