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 measurement site Gosan. 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 as well as dry and wet deposition calculations. The plots shown are from backward model runs using the FLEXPART model. This work was supported by the Norwegian Research Council in the framework of SOGG-EA.

A general description of the FLEXPART backward modeling products and the ideas behind is available as a manuscript in PDF format.

A description of the various products available specifically for this campaign, and the various settings (output domains, resolution of input data, etc.) can be found here.
