Hello Bart:<br>
Thanks<br>
It seems with "curl -l" I am getting only the file names, not sizes.<br>
??<br>
Best,<br>

</div>
</div>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Hello all:<br>
<br>
We are running WRF-Hydro in an operational flood forecasting
system. We download GFS data twice daily from
<a moz-do-not-send="true"
href="http://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/">http://www.ftp.ncep.noaa.gov/data/nccf/com/gfs/prod/</a>
using wget. In order to be sure that we are getting the full
data files, we first get the file sizes with the wget
options: --spider --server-response. We save the file sizes
before download, then compare the sizes after download. If
there's any differences, we restart the download.<br>
<br>
This mostly works well. When downloading the 0.5 degree data
it works perfectly. However when getting the 0.25 data we
have noticed that occasionally the sizes reported by the
NCEP server appear to not be the actual file sizes. This
mismatch does not occur consistently, but rather only about
once in two weeks or so. When this happens, then even
waiting a few hours, and restarting the simulation run does
not help. Our wget --spider and comparison of downloaded
file sizes fails again. Then at the next GFS cycle
everything goes back to normal.<br>
<br>
Has anyone seen this behavior of wget receiving incorrect
file sizes? Is there some other recommended way to ensure
that the downloaded GFS data are the final, complete files.<br>
<br>
many thanks,<br>
Micha <o:p></o:p></p>
