Hi Tony,

Thanks for reporting these. Thankfully, they’re rare these days, but of course we’d like to eliminate them completely, and this helps! :slight_smile:

Tom

Sam has made some changes which should constitute a very robust check on the downloaded files before they’re used to make the final product. He thinks this may put an end to these occasional errors. Hopefully he’s right! :slight_smile:

Hi Tom and Sam,

Fantastic news, greatly appreciated.

Hi Tom and Sam,

NaN error found in GFS Lite 2015-12-03-18Z

Regards,

Whilst I did not see any NaN errors in that line I do see some very strange and totally implausible numbers on that line in the GFS for my location.

Stuart

Same as Stuart, no Nan errors but in both my 177 and 180 lines:

+177,-227.8,-227.9,0.0,266.9,100.0,0.0,5.8,-273.1,29635.1,204.6,7.5,20019.29,
+180,6.1,2.1,18.4,300.2,100.0,1007.8,157.0,-1.6,76.2,64.3,5414.4,-20017.10,

Any more of those strange results? Sam was looking into these issues as of a few days ago. It’s been a crazy last week or so with exams this week. I should be more on top of things over the Christmas break (starting Friday!!!).

Tom

Hi Tom,

No more here, since above.
