City-scale Chemistry Transport Model CityChem-EPISODE

CityChem-EPISODE, developed at Helmholtz-Zentrum Geesthacht (HZG) is designed for treating complex atmospheric chemistry in urban areas (Karl, 2017). The model is an extension of the EPISODE dispersion model to enable chemistry/transport simulations of reactive pollutants on city scale. EPISODE is an Eulerian dispersion model developed at the Norwegian Institute for Air Research (NILU) appropriate for air quality studies at the local scale (Slørdal et al. 2003 &2008). The model is an open source code subject to the Reciprocal Public License ("RPL") Version 1.5, https://opensource.org/licenses/RPL-1.5.Britt Ann Høisker (NILU) is thanked for permission to distribute the CityChem-EPISODE model under the RPL license. This work was in part funded by the BONUS SHEBA project under the joint Baltic research and development programme, co-financed by the European Union's 7th Framework Programme (2007-2013) and the national research funding institutions in the eight EU member states around the Baltic Sea
