Hi Ling, The current (2.2.22) version of netCDF-Java doesn't really understand simple time series data. In the short term, we should be able to figure out a way to read these in as point or trajectory data so that the IDV can read and display the data. In the longer term, I would suggest looking at the convention that Jeff mentions below. It has been submitted to the CF conventions group (http://cf-pcmdi.llnl.gov/) with the current proposed text at http://cf-pcmdi.llnl.gov/trac/wiki/PointObservationConventions It is currently a proposed addition to the CF convention but we expect it will be accepted without large changes. The upcoming (4.0) release of the netCDF-Java library will be able to read time series data that follows the resulting convention. The IDV uses the netCDF-Java library so it will be able to read them as well. If you want to figure out how to get it into the current IDV, Jeff and I can dig into this more. Hope that helps, Ethan > Unidata IDV Support wrote: > > Hi Ling, > > At first glance this file does not seem to have lat/lon or a conventions > > attribute. > > I am moving this ticket to the Java-netcdf group here at Unidata and they > > will be able > > to shed some light on this. > > > > You can also look at some documentation on netcdf observation conventions: > > > > http://www.unidata.ucar.edu/software/netcdf-java/formats/UnidataObsConvention.html > > > > -Jeff > > > > Thanks for the inputs.
