Problem accessing GOES-16 full disk on TDS 5 #799

Closed dopplershift closed 7 years ago

dopplershift commented 7 years ago

So trying to hit some full disk data from NOAAPORT using NCSS:

http://thredds-test.unidata.ucar.edu/thredds/ncss/grid/satellite/goes16/GOES16/20170412/FullDisk/Channel01/GOES16_20170412_000037_0.47_1km_0.0S_89.5W.nc4/dataset.html

I get the following:

IllegalArgumentException: Must specify semi_minor_axis

Looking at the OPENDAP output, This would seem to be the problem:

grid_mapping_name: geostationary
latitude_of_projection_origin: 0.0
longitude_of_projection_origin: -89.5
semi_major: 6378137.0
semi_minor: 6356752.31414
perspective_point_height: 3.5785831E7
sweep_angle_axis: x

I have no idea if that's actually CF-compliant.

CF specifies that the attributes should be semi_major_axis and semi_minor_axis, according to the grid mapping attributes table:

Do you know who to contact to get that fixed? Same person you passed along the compression / shuffle info?

Sent it on...

Thanks @dopplershift!

Now the problem is NCSS complaining:

IllegalArgumentException: Must specify perspective_point_height

even though it's present. PR incoming....
