Urban land-surface models compared

The Finnish Meteorological Institute participated in an international study that tested three different urban land-surface models in the high-latitude city of Helsinki. The models have been designed for forecasting i.a. heating and cooling needs in buildings as well as for assessing the impact of climate change. The results of the study show that the models are mainly able to simulate the weather and climate conditions in urban areas well. It was found important that the presumed thermal properties of building materials are prescribed as realistically as possible in the models.
