It appears that d0 is a time dimension? If so, CF would require a time coordinate for it. In any case, its necessary to distinguish between "CF compliant" and "able to be georeferenced by generic programs using CF metadata". The latter is more stringent, and at the moment i dont think your data

Thanks, Karl! Maybe, I think it's good to mention this possibility in the CF document: coordinate variables can be arbitrary n-Dimension arrays where n > 1. Regarding the 3rd dimension, the 3-D lat/lon coordinate variables have dimension names like below. 447 (Number of HourBoxes) x 3 (1.0

Hi, This file looks CF-compliant to me. I don't think it has to be 2-d. Like John Caron, I am mildly curious what the 3-dimensions represent. regards, Karl On 05-Mar-10 12:30 PM, H. Joe Lee wrote: Hi, I have a satellite data that stores lat / lon information in 3-D array and I'm wonder

Hi, I have a satellite data that stores lat / lon information in 3-D array and I'm wondering how such data can meet the CF convention. Following the http://cf-pcmdi.llnl.gov/documents/cf-conventions/1.4/ch05s02.html page example convention, here's the description of my data:
