| Zusammenfassung |
| Numerous atmospheric transport models (ATM) have been deployed for operational and research activities, each with unique strengths and weaknesses. Several intermodel comparisons have been performed but, to the best of our knowledge, there is still a requirement for a standardised framework in which to compare the performance of the ATM’s. Our group is pursuing a methodology to evaluate the relative performance of ATM’s in a number of application areas. ATM intercomparisons require the definition of a standard output format to drive numerical and graphical procedures for assessing results in a common framework. In our work, we define a common format and develop a set of Open Source graphical and numerical tools to evaluate the models, allowing for side-by-side comparisons.
In this poster we present the evaluation of individual and relative performance of FLEXPART and HYSPLIT in the realm of atmospheric transport modeling environments for radionuclides. We take a small collection of single backwards operational cases and investigate, comparatively, computational performance and graphical representations of the model outputs from runs, considering passive tracers, depositing tracers and various parameterisations for convection. The work exhibited in the poster represents the first steps in the development of tools to compare ATM’s in a common framework for a variety of applications. |
