[ncl-talk] problems with reconstructing EOFs and PCs to original data set

[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) differs quiet a bit from the original data set.

I have attached the sample ncl script in the email.However, the data set (name: gxia_test.bin) is upload to the ftp servers because it can't get through the email security scan (don't know why).

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
