-The local temperature within a complex urban environment is determined by the specific site parameters as well as by the atmospheric conditions. In a surface energy budget model, these factors for soil, vegetation and atmosphere are combined, resulting in a specific surface temperature for a small urban area patch. Since surface temperature is a key element for urban climate, particular attention must be paid to the proper calculation for very different surfaces and soil properties. In this work package, a consistent surface energy budget model will be provided for the <new model> model that is suitable to calculate surface temperatures for bare soils, the wide variety of green surfaces, water bodies, and building façades. Within the framework of these investigations to calculate urban surface temperatures, special focus must be given on specific urban surfaces and undergrounds/substrates like lawns and ecoplasters (lawn paving blocks), paved roads and places, crashed rocks and gravel, trees including shadow, building design elements like green roof or green façade, and water bodies of variable depth.

 ''WP-M4.1: Surface temperatures for mainly sealed surfaces''
 
-In a first step, the energy budget for mainly sealed surfaces will be developed and implemented in <new model>. For paved roads and places the heat transfer into or out of the soil is the dominant part of the surface energy budget. Evapotranspiration and the latent heat flux are hence very small because of the limited interaction with soil water and water availability. In a sensitivity study the most important soil parameters have to be identified in order to specify the minimum input data standards and the necessary degree of accuracy. The subroutine will be tested against available observations for surfaces with different degree of sealing.
