Hi Everybody,
As you may have seen from a couple of other threads, NOAA is having server problems and the GFS data is somewhat unreliable (especially today). See this:
This time, it’s not the “fault” of WXSIM, or of either downloading/processing system option (Chris McMahon’s or Sam Bohler’s). Chris’s system safely makes sure that the data are all good before it will post it, so with bad data slipping in, the last good set is now more than 24 hours old. Sam’s goes ahead and posts what it has, and it’s almost complete (95%, literally, as of the 06Z run), but WXSIM has been rejecting the data as “missing” if any part of it is missing. Of course, that would usually be appropriate, as we don’t want to use missing data!
However, with only one line at a time missing (none of these were consecutive in the sample I looked at), a solution is to average the two adjacent lines. That should be very close to OK, as it’s 3-hourly data. So, I’ve just posted an experimental fix, at
It’s labeled 12.10.1b, and should be able to handle the Bohler data as long as there are not two consecutive bad lines of data. please give this a try, by using the above file to replace the wxsim.exe you have, and also switch from McMahon to Bohler, temporarily. The Bohler site has not generally had heavy traffic, and I still want to default to McMahon as long as it’s available. Possibly Chris might come up with a workaround at some point as well. In any case, NOAA should have their problems fixed before too long.
Thanks for your patience!
Tom
