[ferret_users] problems for concatenate several netcdf files

[Domingos Urbano <dfurbano@xxxxxxxxxxxxx>]

Dear all,

I am trying to concatenate some model outputs but neither option available on the FAQ (http://ferret.pmel.noaa.gov/FERRET_17sep07/FAQ/data_management/multi_dataset.html ) is working. I forced my new time axis to have the same time of each file but it's still not working.

Above my sequence of commands and error message. Anyone could help?

Thanks,
Domingos.

yes? 
yes? define axis/t="01-feb-1971 11:40":"01-jan-2001 11:40":30/unit=days/calendar=

360_DAY t30anos
yes? define grid/t=t30anos gg
yes? let temp_T = t[g=gg]*0 + temp
yes? set variable/title="Pot. Temperature"/units="deg C" temp_T
