[RegCNET] Error in vwnd.1989.18.nc in ERA40 dataset

[bixq]

Dear Kanhu:

Thank you very much for your finding the error !

The file is wrong, I have just redownloaded the file vwnd.1989.18.nc
from ECMWF webpage and update the data in our ftp server.

Several years ago, Mr. Zhang Lei, Mr. Guo Weidong and I work on 
downloading the whole ERA40 files, you know, each file need to be
renamed (like, mv output.nc vwnd.1989.18.nc), probably one of us
made a mistake. This error is also possible due to the previous
ECMWF's code to netcdf data.

When I download the file vwnd.1989.18.nc data, the date range is
from 1989:1:1:18 to 1989:12:31:18 (not the previous 1989:1:1:0 to 
1989:12:31:0).

Anyway, I feel sorry for any inconvience caused by this error. And
if possible, could you please also help me check the other files.
I am also doing the check right now.

Thank you again for your help !
