Currently, as input data are available: meteorologicalinformation, measured background values and volume of traffic for themodeled section of the Beusselstrasse for the first week in November2001.In this modeling phase the traffic information for the main streetnetwork of Berlin is missing. The lack of these emissions explains theoccurring underestimation of the observed concentrations.0501001502002503003504004500 24 48 72 96 120 144 168Hour starting from 1.11.2001µg/m³NOX obs.
