sure, use r.series. Rather than doing the average directly (which
you can do), a common way is to create a sum map and then manually
use r.mapcalc to divide by the number of days to get the avg. I
guess running r.series twice would be just as good..

ps- did that missing header file for the OpenCL version ever make
it into github?
