An urban modeling infrastructure based on WRF was developed coupled with GHG modules to simulate atmospheric transport and predict column-averaged abundances of GHGs. Two evaluation cases were conducted to assess the performance of this infrastructure. By combining DCM with footprints generated by a particle transport model (i.e., STILT), column measurements can be better interpreted and a deeper understanding of the sources and sinks of GHGs and their transports over cities was enabled.weiterlesen
