I'm confused about the orientation of this in 2D mode 1485x1272 is correct,
with 122 bands.

(requires earthdata auth)

gdal raster info "/vsicurl/
https://obdaac-tea.earthdatacloud.nasa.gov/ob-cumulus-prod-public/PACE_OCI.20250501T234515.L2.SFREFL.V3_0.nc";
  --output-format text | grep /rhos
#  SUBDATASET_1_NAME=NETCDF:"/vsicurl/
https://obdaac-tea.earthdatacloud.nasa.gov/ob-cumulus-prod-public/PACE_OCI.20250501T234515.L2.SFREFL.V3_0.nc
":/geophysical_data/rhos
#  SUBDATASET_1_DESC=[1485x1272x122] /geophysical_data/rhos (32-bit
floating-point)

If we drill into the rhos sds X becomes unrolled as the 1485 bands:

gdal raster info "vrt:///vsicurl/
https://obdaac-tea.earthdatacloud.nasa.gov/ob-cumulus-prod-public/PACE_OCI.20250501T234515.L2.SFREFL.V3_0.nc?sd_name=/geophysical_data/rhos";
--output-format text | grep "Size"
#Size is 122, 1272

We can (redundantly??) cast via mdim to get 1485x1272, but then we've lost
the geolocation arrays:

gdal raster info "vrt:///vsicurl/
https://obdaac-tea.earthdatacloud.nasa.gov/ob-cumulus-prod-public/PACE_OCI.20250501T234515.L2.SFREFL.V3_0.nc?transpose=/geophysical_data/rhos:0,1";
--output-format text | grep "Size"
#Size is 1485, 1272

At any rate in the default case the geolocation arrays don't match the data
orientation.

Cheers, Mike
