Hi Yun Li, If the name of the "Fake Time" axis is T, then Ferret should detect that axis as an axis in the T direction. Could you tell me what version of Ferret are you using, and could you send me the output of the Unix ncdump command ncdump -h HADISST_1_1_SST_2004.nc Ansley Yun.Li@xxxxxxxx wrote: Dear All, I have a copy of monthly HADISST_1_1_SST_2004.nc as follows. yes? use HADISST_1_1_SST_2004.nc yes? show data currently SET data sets: 1> ./HADISST_1_1_SST_2004.nc (default) name title I J K L T Fake time 1:12 ... ... ...
