The assessment was focused on the issue of modelling of meteorological fields and
air quality in conditions of conurbation with regard to presence of urban heat island
phenomenon. Within the project framework, modelling tools for air quality evaluation were tested while meteorological parameters and chemistry of the atmosphere
were taken into account. Based on the acquired findings from the base state, the
horizon of fulfilment of land use plan in its present form and the variants of urban
and traffic concept were assessed.
The project assessed the following scenarios: baseline state, fulfilment of the
land use plan, low-emission zone and implementation of a green belt. In addition,
sensitivity to the expected climate change was studied.
In terms of UHI, the most important was evaluation of green belt scenario, i.e.
state when the transport concept and vehicle fleet composition corresponds to the
year 2020 and fulfilment of the land use plan is presumed with the exception of
areas defined as green belt whose land use is assumed to be changed into forest area
or forest park.
