<br><font size=2 face="sans-serif">I'm looking to use MET to verify WRF
model forecasts for the Western US and Eastern Pacific for April of this
year. Do you know of an archive of PREPBUFR data? Also in testing
MET I used NAM PREPBUFR data that I obtained from the NCEP site you link
to on the MET webpage. This data would probably meet my needs but
there did not appear to be an archive, only the last couple of days, and
its not clear to me for the files I did use what observation times are
in a file. For example for today there are the following files listed
among others</font>
<br>
<br><font size=2 face="sans-serif">ndas.t00z.prepbufr.tm03.nr </font>
<br><font size=2 face="sans-serif">ndas.t00z.prepbufr.tm06.nr </font>
<br><font size=2 face="sans-serif">ndas.t00z.prepbufr.tm09.nr </font>
<br><font size=2 face="sans-serif">ndas.t00z.prepbufr.tm12.nr </font>
<br>
<br><font size=2 face="sans-serif">I did download and convert some for
these files (for 12Z on 20080905) to NetCDF using pb2nc and dumped
headers/variables using ncdump to find out observation times but
is there something in the file name that will tell be this or give me an
indication of the range of observation times in the file? I
assume the 00z means 00Z cycle for the date of the directory but what does
the 03, 06,09 etc mean? I would like to verify daily 36 hours forecasts
so I'll need to collect files that contain the data I need and label them
appropriately. </font>
