The aim of this simulation was to create an obstacle resolving model (ORM) dataset to test and apply the newly established AtMoDat standard (Ganske et al., 2021) on ORM data, as a part of the AtMoDat project (see: https://www.atmodat.de/). The simulation results show the distribution of passive tracer and wind field within the city center of Hamburg, Germany. Emitted tracer represent particulate matter (pm10), emitted from green spaces in the city center. Only dynamical effects are calculated in this simulation. The model domain covers an area of 1000x1000x8000 m, using a non-equidistant grid with an spatial resolution of 2.5 m in horizontal and 5 m in vertical direction with increasing grid cell size towards the model boundaries. Information about the location and height of the obstacles are provided within the dataset. The model domain is based on the study of Salim et al., (2015). The simulation covers one hour model time, starting at 4 am model time, with a temporal resolution of 5 minutes. This dataset contains a selection of output variables, control variables are not included.
