The NILU Atmospheric Backward Transport Analysis Products

by Andreas Stohl


What this site is about

This site presents a resource to interpret transport processes and how they influenced measurements at the station. It attempts to replace trajectory calculations -- to date, the major tool used for that purpose -- with quantiative dispersion model runs including full turbulence and convection parameterizations. The plots shown are from backward model runs using the FLEXPART model. A description of the various products derived from the backward runs can be found here.

Disclaimer: I make these products freely accessible. If you feel that using them contributed significantly to one of your publications, I would appreciate if you could acknowledge that, or offer co-authorship, depending on how important you feel that these products actually were for your work. This will allow us continuing this kind of service also in the future. Of course, on request I can also produce custom-made plots with adjusted plotting domains, better image quality, etc., for use in peer-reviewed publications.

Backward modeling products are available for the following months:
