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 aircraft measurements during the recent ASTAR 2004 campaign. It attempts to replace trajectory calculations -- the major tool used so far 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.

Backward modeling products are available for the ASTAR flights on the following days
