• Community Land Surface Model v3.5 (CLM3.5) as an optional land surface
parameterization
• Urban surface treated by coupling with Single Layer Urban Canopy Model
linked to SUBBATS surface scheme
• Applied by Charles University, Prague
CLMM (Charles University Large Eddy Microscale Model)
• LES tool for simulation of the flow in microscales with complex terrain or
structures solving CFD problems
• In addition to flow equations it includes transport equation for scalars like
temperature, moisture and passive pollutants
• Applied by Charles University, Prague

1.3.1.1 Introduction
In 2050 the global fraction of urban population will rise to a level up to almost 70 %,
which means that around 6.3 billion people are expected to live in urban areas. Next
to that development a rise of the global temperature of about 0.2 K per decade for
the twenty-first century is projected within the range of the SRES scenarios of the
Intergovernmental Panel on Climate Change (Intergovernmental Panel on Climate
Change – IPCC) for Europe (Wagner et al. 2013).
It’s predicted, that extreme events are to increase in the future, which means
more and heavier storms, precipitation events and thus increased danger of flooding,
occurrence of heat waves or days with high air pollution, especially dangerous in
combination with high temperature periods (Beniston et al. 2007).
