climatology

I'm interested in generating my own climatology baseline, rather than use the one provided. How would I do this? My intuition tells me it is all of the years combined, and then averaged, but is that proper usage of the rasters? Is there a better way?

you can try l2bin and l3mapgen.

"all the years combined" is a bit vague. Are you trying to combine the level-3 annual composites or seasonal composites or something else or perhaps level-2 files? If it is level-3 annual files then to avoid a seasonal or other bias don't use incomplete years (such as 2002 for Aqua).

Also note to aggregate a mean of multiple files you cannot use the MathBand tool to find the sum and divide by the number of files, as the number of valid pixels is dependent on each pixel. The SeaDAS aggregation tool options for this purpose would be the OCSSW processors l2bin and l3bin. There is also the more generalized GUI tools Mosaic and Level3 Binning.
