I have a mosaic dataset that contains a time series of elevation dems that gets added to continuously.

I would like to create change surfaces of current month dem raster minus last month dem raster that is avaliable as a reference mosaic or portal service.

how can i do this dynamicly so as we roll into the next month the change surface used by users shows the new months change? can I do this via reference mosaic/raster function? or what is best method?

I understand that for a number of days at the begining of the month this change surface will return no result, as its usually some time at the end of week 1 start of week 2 the current month's capture is loaded. But this is acceptable.
