Mapped to AR6 Scenario database area

[CGL5230]

Hi!
Recently I've been using Demeter to downscale land use data from AR6. the AR6 output does not have the same area as the AEZ area set by default by GCAM/Demeter (below). So how do I use the AR6 output data to produce a format that matches Demeter's downscaling?

The geographic portion of the AR6 output is not as fine as the AEZ in GCAM, how should this be handled? My ideal processing model would be to directly downscale the individual areas directly from the AR6 output directly with Demeter.Is there a quick and easy way to do this?
