Hi all,
In support of that, in Europe the marine Copernicus user community express the
same need, to be able to subset data across the grid boundary.
We are currently not using Thredds/subsetter in the project notably because of
that.
You say that the version 5.0 “mostly” fix that ?
I will be closely watching the date of this release and test it.
Best regards,
Tony Jolibois

Objet : Re: [thredds] NCSS Queries Not Spaning/Crossing Dateline
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.

Hi Michael-
In the current versions of TDS/netCDF-Java, you cannot subset across the grid
boundary. 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.

Is there some trick I am not understanding for making NCSS queries
that span the 180-degree east dateline? 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.

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.
