Update 3D field during model run

[rconrick]

Hello,

I have a field of aerosol information from the ERA-CAMS model that I've added to wrfinput and wrfbdy for use by the Thompson-Eidhammer aerosol aware microphysics. My problem, of course, is that for runs longer than ~12 hours the surface aerosol sources get lost due to advection.

Is there a way to load my 3D aerosol grid every time the boundaries update? I'm thinking of this like the SST update feature, but with a 3D grid.

My alternative would be to run the model for short bursts (~3 hr) with restarts, and update the field within the restart files. This method doesn't thrill me, though.

Any thoughts?

Thank you!

Option 1 is obviously robust, which can update aerosols in the way similar to SST update. Note that this option involves lots of coding work.
Option 2 certainly works, although you need to go through the trouble to restart the run many times.
