Hi Joe, re: > I have a small question > > I have a line in my LDM conf to pull data down > request FSL2 "(.*000Hour)" idd.unidata.ucar.edu OK. Just so you know, the '.*' preceeding '000Hour' is not necessary, and the only reason to enclose the regular expression in parentheses is if there is a second request with the same pattern and you want to force both feeds to operate in PRIMARY mode. The following REQUEST will likely be just want you want/need: request FSL2 "000Hour" idd.unidata.ucar.edu By the way, I assume from this pattern that you are interested in the HRRR data; correct? re: > Is there a way I can modify it to request > > request FSL2 > "(.*000Hour|.*001Hour|.*002Hour|.*003Hour|.*004Hour|.*005Hour|.*006Hour)" > idd.unidata.ucar.edu > every 6 hours > > request FSL2 "(.*000Hour)" idd.unidata.ucar.edu > the rest of the time There is ** IF ** there is a part of the Product IDs that will match only every 6 hours. Also, your REQUEST could be written more compactly as: request FSL2 "00[0123456]Hour" idd.unidata.ucar.edu Assuming that you are trying to get the HRRR data, then one of the last fields looks to be the date/time in the form CCYYMMDDYHHMM. Here is a portion of a 'notifyme' output that shows some of the Product IDs: Feb 26 00:19:12 notifyme[29468] INFO: 687326 20130225232621.583 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.REFC.EA.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 430611 20130225232621.596 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.BMIXL.CloudTop.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 429679 20130225232621.602 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.5WGH.CloudTop.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 1285428 20130225232621.614 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.UGWD.EA.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 792242 20130225232621.629 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.VGWD.EA.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 1151492 20130225232621.640 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.Vis.Surface.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 407617 20130225232621.651 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.REFD.1000m_FHAG.201302252100.* Feb 26 00:19:12 notifyme[29468] INFO: 1006365 20130225232621.666 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.MAXUD_1Hour_Missing.40000Pa_to_100000Pa_Isobaric.201302252100.* Feb 26 00:19:13 notifyme[29468] INFO: 964431 20130225232621.678 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.CNWAT_1Hour_Missing.40000Pa_to_100000Pa_Isobaric.201302252100.* Feb 26 00:19:13 notifyme[29468] INFO: 516072 20130225232621.687 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.GVV_1Hour_Missing.50_to_80_Sigma.201302252100.* Feb 26 00:19:13 notifyme[29468] INFO: 625413 20130225232621.694 FSL2 000 GRIB2.FSL.HRRR.1905141_Lambert.006Hour.PMSL.MSL.201302252100.* ... I believe that you could fashion two ~ldm/etc/ldmd.conf REQUEST lines that would do what you want (two are needed, not one): # Get the 0 hour forecasts whenever they are available request FSL2 "000Hour\." idd.unidata.ucar.edu # Get the 1-6 hour forecasts every 6 hours request FSL2 "00[123456]Hour\..*2013....(00|06|12|18)" idd.unidata.ucar.edu I think that this will work, but, of course, the patterns need testing. re: > this dataset is roughly every hour, and say every 6 we want to pull the > forecast ones in addition to the actual, but not all the time.... I understand. Try the example above, and please let us know if it works the way you want/need. re; > Thanks for your help No worries.
