Hi, I'm computing monthly climatologies from a set of unevenly spaced series of temperature records using: def ax/t=15-jan-1985:1-dec-1995:`365.25/12`/units=days t85_95m def grid/x=x/y=y/t=t85_95m mgrid def var mclim=SST[gt=mgrid@ave] Is there a way of listing the actual SST values used to compute the average for a given month ? Thanks! Paulo.
