ERDDAP can serve the time series. At the moment it does not have the type of
server-side function you are describing. I believe GDS and F-TDS have such
capabilities.
We have been holding back on doing this in ERDDAP for some simple reasons:
1. There is no agreed upon syntax for such requests.
2. It could open up your server to quite large amounts of data processing
3. The processing requests could take long enough that it would require an
asynchronous response.
All of these things imply not insignificant changes in the service.
