Dear Dr Bi and RegCNET users,<div><br><div>I have run RegCM3(March 2008 version) for 21yrs(i.e. 1980-2000) with <b>ERA40</b> as the lateral boundary conditions.</div><div><br></div><div>The physics option we used for convective precipitation is <b>Grell scheme(Fritsch &amp; Chappell </b>closure assumption).</div>

Dear Kanhu:<br>
<br>
Thank you very much for your finding the error !<br>
<br>
The file is wrong, I have just redownloaded the file <a href="http://vwnd.1989.18.nc" target="_blank">vwnd.1989.18.nc</a><br>
from ECMWF webpage and update the data in our ftp server.<br>
<br>
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<br>
renamed (like, mv <a href="http://output.nc" target="_blank">output.nc</a> <a href="http://vwnd.1989.18.nc" target="_blank">vwnd.1989.18.nc</a>), probably one of us<br>
made a mistake. This error is also possible due to the previous<br>
ECMWF&#39;s code to netcdf data.<br>
<br>
When I download the file <a href="http://vwnd.1989.18.nc" target="_blank">vwnd.1989.18.nc</a> data, the date range is<br>
from 1989:1:1:18 to 1989:12:31:18 (not the previous 1989:1:1:0 to 1989:12:31:0).<br>
<br>
Anyway, I feel sorry for any inconvience caused by this error. And<br>
if possible, could you please also help me check the other files.<br>
I am also doing the check right now.<br>
<br>
Thank you again for your help !<br>

Dear Dr. Bi and Regcnet users<br>
<br>
There is an error in <a href="http://vwnd.1989.18.nc" target="_blank">vwnd.1989.18.nc</a> in ERA40 data-set.<br>
While opening the data file it is showing that the time is<br>
1990:1:1:0 whereas the time should be 1989:1:1:0<br>
The error message is shown below<br>

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