Heiko, Moreover....The netcdf-java 4.6.X recognizes the standard_name='ensemble' for Ensembles Axis Type.
https://github.com/Unidata/thredds/blob/master/cdm/src/main/java/ucar/nc2/dataset/conv/CF1Convention.java#L157-L160but 'ensemble' is not a recognized CF standard_name. It should be 'realization' as you have put into the ensemble_member
The netcdf-java 5.0.0, adds 'realization' as possible standard_name value for Ensembles Axis Type

Hi, we just extended our meteorology forecast runs with ensemble members. Data without ensemble/realization dimension can be found here: http://thredds.met.no/thredds/dodsC/arome25/arome_metcoop_test2_5km_latest.nc and these work well with the netcdf-java base software like thredds/idv/ncwms , e.g. precipitation_amount_acc(time,height0,y,x) As soon as we combine several realizations/ensembles into the same file http://thredds.met.no/thredds/dodsC/meps25files/meps_allmembers_full_2_5km_latest.nc all gridded feature stop working for precipitation_amount_acc(time,height0,ensemble_member,y,x). We can still use opendap, but ncwms and idv no longer find this variable. netcdf-tools still detect the variable as a FeatureType GRID f:D(5)->R(7) (in FeatureType->FeatureScan) but is not able to detect the coordinateSystem in FeatureType->Grids. I even tried to remove the height0 dimension (which is of size 1), but without any change. Is 'standard_name=realization' an unsupported feature of netcdf-java? There was a longer discussion about it in 2010: http://mailman.cgd.ucar.edu/pipermail/cf-metadata/2010/053546.html Should we use some axis="ensemble" or _CoordinateAxis keyword to help detect the ensemble dimension? Or is the problem within thredds/ncwms/idv not able to deal with other dimensions than x,y,z,t? Sorry for cross-posting, not really sure where the problem lies. We're using thredds 4.6 and netcdf-java toolsUI 4.6 Best regards, Heiko
