The NILU Atmospheric Backward Transport Analysis Products for MILAGRO, INTEX-B, IMPACT, MEGAPLUME

by Andreas Stohl


What this site is about

This site presents a resource to interpret transport processes and how they influenced aircraft measurements during recent aircraft campaigns (MILAGRO, INTEX-B, IMPACT, MEGAPLUME). 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.

For completeness, forward runs for three continental tracers, plus an Eastern European fire tracer, have also been calculated. You can produce a variety of plots based on these runs, using our interactive plotting tool, and selecting "MILAGRO_ETC" as the project: The interactive tool for producing custom-made plots

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.

Backward modeling products are available for the following flights and other data sets:
