Hi all, How ferret can be used with netCDF data compressed by gathering as it is described in CF convention (http://www.cgd.ucar.edu/cms/eaton/cf-metadata/CF-1.0.html#gath) ? When I use the usual command "use", "show data", "show grid" ferret seems not to understand this type of compression. See below the ncdump of a netCDF compressed like this. Thanks in advance for your comments.
