Linking urban micro scale models -The models RayMan and SkyHelios

In order to derive complex indices for the evaluation of climate in urban and other planning levels information and data about climate and climate influencing factors are of importance. The models RayMan and SkyHelios are two free available micro-scale models for the calculation and estimation of Sky View Factor, sunshine duration, shadow and in general radiation fluxes. In addition, RayMan is able to estimate the most modern thermal indices used in human biometeorology. The two models have the possibility to correspond and link several data formats in order to produce and transfer information for further processing in urban climatological studies and issues.
