Responding in seconds on a standard PC, LINCOM is being widely applied as "driver" for real-time atmospheric dispersion models used to assess emer- gency response over non-uniform terrain, for instance for the Vandenberg AFB (CA) emergency handbook, and also in the EU-RODOS Real-Time On-Line Decision Support system. However, without the energy balance present (the t
