[ncl-talk] Problem with dimensions when writing variable to netcdf

[Karin Meier-Fleischer]

Hi Anne,

you have to create the named dimension for time_counter and commit the 
time_counter data:

   time_counter              = tofloat(time)
   time_counter!0            = "time_counter"
   time_counter&time_counter =  time_counter

Bye,
Karin
