Inverse Transport Modeling of Non-CO2 Greenhouse Gas Emissions of Europe

In general, it can be concluded that with the (T)SVD technique emissions can be estimated with high accuracy, provided that the modeled source-receptor matrices are of high quality as well. In the last experiment the model error was 0–10% resulting into emission estimates that deviate 0–15% from the original input ones.For real world data the (T)SVD inversion method allows to derive satisfying results from imperfect models and concentration data. In order to improve the accuracy of the resulting emission fields more accurate models and more measurement data will (at more stations within the source areas and with longer tie series) be needed. The tools described in this paper allow to develop a feeling of where to go in order to achieve this at cost-effective way.
