[ferret_users] ensemble or compare data from two time series

[Xiaoyu Bai <xbai1@xxxxxxxx>]

Dear ferreters,

I am trying to ensemble RCPs (2005-2099) and control runs (1949-2005) together but keep getting T axis differs error.

*** NOTE: Variable "PRECIPITATION" excluded from aggregate: T axis differs among members
 **ERROR: error defining aggregate dataset: No valid datasets or datasets share no variables that can be aggregated.

It makes sense for pyferret to think the time axis are different. But comparing the @AVE value from different time series should also make sense to pyferret. I am wondering how to solve this problem.

By the way, I already tried to read data in separately and do @AVE first then compare. It still showed the same error because the data still come from different time series.
