That is very odd. I just had a look at the code for the reader, and both the units and the axis properties should have caused the reader to treat the dimension as time.
Is there a way I can get a copy of the netCDF file? I tried going to the web site you posted at the beginning of this thread, but I couldn't figure out how to download a netCDF file.

Time as a UOM might be used in any property, not just dimensions. What do you think?

For example, the netCDF file tos_O1_2001-2002.nc used for VTK testing (https://midas3.kitware.com/midas/item/206312<https://urldefense.proofpoint.com/v2/url?u=https-3A__midas3.kitware.com_midas_item_206312&d=CwMGaQ&c=uGuXJ43KPkPWEl2imVFDmZQlhQUET7pVRA2PDIOxgqw&r=PPcXhptMPNzBCwHx-o1zqg&m=A7bpyohhfVnNQoUi0GE2BJS2jE2OkxogntGvLqTmVGM&s=HGoAZZDUus7tmDI-abU30H7Ij8Qg_EeQwanbaawq2-w&e=>) has a time dimension and it loads just fine. As I recall, the CF convention defines the time dimension using a units property on the variable that specifies some unit of time. One problem that has occurred in the past is that sometimes the time unit is something that the reader does not recognize as time. What is the time units used in your data set? -Ken From: ParaView <[email protected]<mailto:[email protected]>> on behalf of Ken Sheldon <[email protected]<mailto:[email protected]>> Date: Saturday, April 23, 2016 at 9:51 AM To: "[email protected]<mailto:[email protected]>" <[email protected]<mailto:[email protected]>> Subject: [EXTERNAL] [Paraview] Time Variables in CF Conventions I am trying to read a CF Conventions NetCDF file (Sea Surface Temperature from NOAA). The CF reader in ParaView recognizes the axes and the data correctly. However, it does not seem to recognize the TIME dimension. Is anyone here reading CF (Climate Forecasting) files successfully?
