Luis:
As far as I know, newUnit()'s parameters are:
data, name-for-unit, valid-unit
If you use the Formula: Misc -> Change Unit, you would be prompted
for the name and the unit.
I picked "deg_K" since I thought perhaps your ts_ data was some kind
of temperature.
It is very important to use the values in the udunits (like "deg_K")
for all your units....if you write the netCDF files, then I suggest
you include the correct values -- things like "degrees" don't mean
much. If you did not write the files, I suggest you talk to whomever
did and encourage them to make the appropriate chages.
Best wishes,
tom
