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.

Content-Type: text/plain Hi, I am reading in a netcdf file and applying subsetting and reduction criteria. I am trying to get my head around the fact that a variable can be based on less than the full set of available coordinate variables. For example, in a FOAM netcdf file I am looking at there are depth, lat and lon coordinate variables and a number of data variables. One such variable is called ICEC and it is recorded at only lat and lon. My question is, if I am creating an output netcdf file which is going to contain just the ICEC variable what should I output in the global metadata? Should I output all three coordinate variables? What shape should they be? What shape should they be when I include another variable which is based on different coordinate variables and has different shape? Thanks Brian
