[ncl-talk] bug found when using the EOF to reconstruct the data

[Xia, Geng]

??

Hi all


Recently, I try to do the EOF analysis using ncl for my research topic.  However, I find that after I did the EOF analysis (using function eofunc and eofunc_ts), I can't reconstruct the result back to the original dataset (using function eof2data). The reconstructed data (including all EOFs and PCs) I got differs quiet a bit from the original data set.


I have tried different function such as eofunc_Wrap but the result does not get better.


I have attached the sample ncl script I use and the data set in the email. Hopefully you can take a look.

I have commend on the steps I did so It should be very straight forward.


my ncl version is 6.1.2

the version of Linux is  x86_64 x86_64 x86_64 GNU/Linux?


Hope you can take a look at my problem

Best


Geng Xia
