Hi, The sign of the functions returned is only important in that the sign differs between one function and another; which is positive and which is negative is arbitrary. You will want to compute the statistics for the EOF computation using EOF_STAT or EOFSVD_STAT and look at the percent variability explained by the eigenfunctions returned. http://ferret.pmel.noaa.gov/Ferret/documentation/users-guide/appendix-a-external-functions/EOF-STAT Ansley On 3/19/2016 4:25 AM, Krishna Ramesh
