John, We've discussed this issue before, but just checking in to see if recent changes to NJ make this possible: The ocean community has an increasing amount of unstructured grid ocean model forecast data which we would like to aggregate and deliver via OPeNDAP. Examples datasets: http://www.smast.umassd.edu:8080/thredds/forecasts.html If we try FMRC aggregation, we get "no grids found" because unstructured grids only have a "time,z,node" dimension instead of "time,z,j" dimensions. If we could add a singleton dimension, unstructured grid would be recognized as "grids" and we could use FMRC as well as higher level routines to return the vertical coordinates, but currently there is no way to add a singleton dimension using NcML. Within a year we hope to have an unstructured grid class for NetCDF-java, but in the interim, would it be possible to read this data as GRID somehow (provide a way to add the singleton dimension, or map into the grid structure on read)? -Rich -- Dr. Richard P.
