I would like to load point data to the idv for the first time. The data
I'm using is in NetCDF CF-1.0 convention, having a station axis
connected to longitude/latitude coordinates, i.e. :
netcdf test { dimensions: station = UNLIMITED ; // (94 currently) time = 366 ; dim_charlen = 4 ; variables: float EPDL5(station, time) ; EPDL5:_FillValue = -9999.f ; EPDL5:component = "ammonium" ; EPDL5:component_id = "5" ; EPDL5:long_name = "ammonium, precip" ; EPDL5:matrix = "precip" ; char station(station, dim_charlen) ; short time(time) ; time:units = "days since 2002-01-01 00:00:00 UTC" ; double lon(station) ; lon:long_name = "station longitude" ; lon:units = "degrees_east" ; lon:_FillValue = -999999. ; double lat(station) ; lat:lat_name = "station latitude" ; lat:units = "degrees_north" ; lat:_FillValue = -999999. ; // global attributes: :Conventions = "CF-1.0" ; }Trying to read it as URL->Point Data gave me just one field 'Point Data', and while trying to 'Create Display', I get the error message:
Unable to make PointObsDataset from file Trying to read it as File didn't gave me a field at all.I tried also to connect to one of the point-data servers, to look for an example, but I haven't been allowed to access the servers.
So, what do I have to do to display point data in IDV, and compare it i.e. as timeseries to one of my grid-cells.
Best regards, Heiko
