Dear Thredds community, I was wondering when 2 issues will be solved, and if it is or will be solved in which version of TDS. Many users here in Europe are impacted (CMEMS community), as well as Hycom users apparently. - The capacity of NCSS to manage subset across the grid boundary - A bug on netCDF 4 output writing : https://github.com/Unidata/thredds/issues/330 Is the TDS 5.0 the good one ? If yes, is this version considered as a stable version ?

Indeed, we have this (mostly) working on our 5.0 development branch. We're not really sure about when we'll release 5.0, but it should be by the end of the year at the latest.

Since your model runs -180 to 180, that's what you are running into. For model output that runs 0-360, the problem is at the prime meridian. I think this is to be fixed in the next iteration (5.0?), but I'm sure Unidata can verify that.

We've had users on the HYCOM.org forum asking about this, and I cannot get a netcdf object which does not stop at 180-degrees east. http://www.unidata.ucar.edu/software/thredds/current/tds/reference/NetcdfSubsetServiceReference.html#Subsetting We are using the latest 4.6.3 http://ncss.hycom.org/thredds/catalog.html 1. Start with our HYCOM reanalysis product, http://ncss.hycom.org/thredds/ncss/grid/GLBa0.08/reanalysis/dataset.html 2. See if you can successfully get data that spans the dateline, i.e., West 170 to East 200 If successful, please let me know how to accomplish this. -- Don Murray NOAA/ESRL/PSD and CU-CIRES 303-497-3596<tel:303-497-3596> http://www.esrl.noaa.gov/psd/people/don.murray/ _______________________________________________ thredds mailing list thredds@xxxxxxxxxxxxxxxx<mailto:thredds@xxxxxxxxxxxxxxxx> For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/ Cliquez ici<https://www.mailcontrol.com/sr/0rp!JUjVdg7GX2PQPOmvUo1yZ91kITL4y92GS5Ba1a1R!khHnxdqh5TV!DiD!7MCQGpUKsswpNw5N50IUBelLw==> si ce message est indésirable (pourriel)._______________________________________________ thredds mailing list thredds@xxxxxxxxxxxxxxxx For list information or to unsubscribe, visit: http://www.unidata.ucar.edu/mailing_lists/

Dear Ryan, Ok, new issue. Do you have a planning for the correction ? More generally, do you have a roadmap for Thredds Data Server developments ? The next versions, what will be corrected etc ? Thanks. Best regards, Tony De : Ryan May [mailto:rmay@xxxxxxxx] Envoyé : samedi 12 décembre 2015 00:30 À : Jolibois Tony Cc : THREDDS community; joan.sala@xxxxxxxxxxxxxxxxxxxxxxxx Objet : Re: [thredds] TDS NCSS: issue with netCDF4 files as input and netCDF4 requested as output Thanks for the files, I'm able to reproduce the problem locally. Unfortunately, it doesn't appear to be related to the issue #301 as I thought. I've opened a new issue: https://github.com/Unidata/thredds/issues/330 You can follow any progress there as I continue to dig.

I've also added part of catalina.out, the java_opts used, and the Thredds configuration (simple joinExisting aggregation). Note that it's only when you request netCDF4 as output that we have an error. Best regards, Tony Hi Tony, Can you provide an example of the NetCDF-4 input file so that we can recreate the problem locally?
