Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

[cf-satellite] Coordinate variables - center vs. corner of the pixel

NOTE: The cf-satellite mailing list is no longer active. The list archives are made available for historical reasons.

I'm wondering if there is a standard for center vs. corner when writing 
the coordinate variables for latitude/longitude or projection x/y of 
satellite imagery for netCDF?  GeoTIFF supports both conventions.  HDF 
appears to specify the UL corner of the pixel.  Has anyone settled on a 
convention for netCDF or CF Metadata in general?

Thanks,
