Hello all,

 

I have a dataset that works correctly with the grid subset, ncWMS, and
any other NetCDF tool I can come across.  It is failing with the THREDDS
NetCDF subset when requesting point data.

 

Dataset:
http://staging.asascience.com:8989/thredds/catalog/Cadiz/Currents/catalo
g.html?dataset=Cadiz/Currents/EGM200_3.nc

 

Point Subset:
http://staging.asascience.com:8989/thredds/ncss/grid/Cadiz/Currents/EGM2
00_3.nc/pointDataset.html

 

Request:  http://staging.asascience.com:8989
/thredds/ncss/grid/Cadiz/Currents/EGM200_3.nc?var=u_wind,v_wind&latitude
=35&longitude=-6&temporal=point&accept=xml&point=true&time_end=present&t
ime_duration=P3D

 

Trace:

Is this most likely caused by an incorrect dataset?
