Times are out of order on two of your datasets

[Roy Mendelssohn - NOAA Federal]

Please look at the following dataset:

https://tds.hycom.org/thredds/dodsC/glb_analysis.html

for this I did:

https://tds.hycom.org/thredds/dodsC/glb_analysis?MT[1700:1:1800]

the results show at the end:

41128.0, 41129.0, 41130.0, 41131.0, 41132.0, 41133.0, 41134.0, 41135.0, 41136.0, 41137.0, 41138.0, 41139.0, 41140.0, 40180.0, 40181.0, 40182.0

You can see the times are not ordered.

Thanks,

-Roy

Roy,
This (hidden/legacy) THREDDS aggregation "glb_analysis" is dated and
not recommended for use anymore. It was an aggregation "of
convenience" joining (crudely) all/multiple GLBa0.08 experiments (90.6
to 91.2). Any time overlap from the experiment that comes next will
cause this time order issue to occur as its time array gets appended
to the existing time array.

The GOFS 3.1 data should be used instead.

<dataset name="1/12 degree HYCOM + NCODA Global Hindcast Analysis (Combined)"

</aggregation>
</netcdf>
</dataset>


If you explicitly want this GOFS 3.0 data, then I would recommend the
use of the individual experiment aggregations here,

https://www.hycom.org/dataserver/gofs-3pt0/analysis

e.g.,
https://tds.hycom.org/thredds/catalogs/GLBa0.08/expt_91.2.html
...
https://tds.hycom.org/thredds/catalogs/GLBa0.08/expt_90.6.html

Thanks. We want to use the recommended option. I will change to that tomorrow.
