We are trying to model an arbitrary shape of an area source. Can someone help us with this, we are not sure if FLEXPART has an option for this. Or other wise, when we try to split the arbitrary area source into smaller rectangular areas, the outputs generated for each small area source comes separately. Does FLEXPART not solve for all the multiple area sources together?

We are using FLEXPART for forward model run and obtaining concentrations at 3 different levels. There are few basic doubts for which we need some clarifications.

1. Whether the concentrations that we get in output are column integrated or at a particular height only?
2. If it is at a particular height only, what is the band of height within which the concentrations have been given?
3. And if it is column integrated, at the second level output, is the average along the column from the earth's surface or from the previous height/level.
4. Is there any restriction on the lowest height level at which the output can be obtained or to what minimum height would the simulations give us reliable concentration

Is there an option to obtain output concentrations with respect to ground or mean seal level or different pressure levels. We understand that in OUTGRID, heights can be specified, but those are with respect to what? In the releases file, there is an option for above ground, above sea level or pressure in hpa. But does that correspond to outputs also?
