The first work package aims to contribute to an improved understanding of microclimatic influences of the heterogeneous urban land-use and morphology. We intend to develop and implement state of the art methods to analyse the local energy balance by specific spectral response pattern of the modelling domain on different synoptic conditions. Secondly a set of extensive climate relevant urban surface parameters will be developed which includes spectral features, land cover, geometric/morphologic features and advanced anisotropic parameterisations of the urban canopy energy balance as well as urban roughness.
Those parameters shall give a better representation of micro climate relevant city morphology and thus allows to a certain extent explanation of the spatial variation within urban climate. Therefore they will be utilised for empirical modelling in work package II.
Furthermore these parameters will be used to automatically classify regions of homogenous urban climate conditions (climatopes), which shall remain related to urban landuse types in order to increase applicability in urban and regional planning and enable a dynamic urban land use modelling in work package III. They can also be regarded as a first step to an expert system for analysis and assessment of climate relevance of urban structures.
