Median and geometric mean
Request from Andy Sawyer:
On the averaging front, is it possible to calculate medians and geometric means, or only arithmeric means?
Additional comment from Andy:
For aerosols in particular, we’re interested in adding geometric means because aerosol optical depth varies lognormally (i.e. linear in log space). (Note the MODIS products don’t do this so it is not necessary for continuity.) Still for a first pass I can add a ‘log AOD’ SDS and run the gridding on that as the calculation would be equivalent. Medians would also be welcome but I realise this is computationally tougher since you can’t take a running average, and again MODIS doesn’t have that so it isn’t needed for continuity. I agree it makes sense to start simple!
This ties to issue #4 (closed) about supporting MOD08 features
