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 !

Dear Dr. Bi and Regcnet users

There is an error in vwnd.1989.18.nc in ERA40 data-set.
While opening the data file it is showing that the time is
1990:1:1:0 whereas the time should be 1989:1:1:0
The error message is shown below

ga-> sdfopen vwnd.1989.18.nc
Scanning self-describing file:  vwnd.1989.18.nc
SDF file vwnd.1989.18.nc is open as file 1
LON set to 0 360
LAT set to -90 90
LEV set to 1 1
Time values set: 1990:1:1:0 1990:1:1:0

ga-> set t 1 365
Time values set: 1990:1:1:0 1990:12:31:0

So please suggest me for VWND.1989.18 data which file I should use.
Thanks in advance.
