Hi,
This is something that others run into. The solution in Ferret
is something we call "timestamp".
Here's another thread on this topic.
../fu_2016/msg00201.html.
The first followup talks about Ferret's Timestamp solution, and the
second talks about using NCO operators to add time coordinates to
the files, and then use Ferret to describe the time coordinates.
I am not familiar with CDO. Others may suggest ways to do that in a
different way. I would suggest either using the second followup to
the thread mentioned above, Russ Fiedler's idea. Or use NCO to add
a coordinate variable to each individual file. At that point you
could use Ferret's "tseries"
time aggregation capability to define a virtual time series with the
files, and then if needed, redefine the time axis to have the units
and time origin that you want.

Dear
Ferreters,
I am using
monthly data which is not having any time axis information
and every month is in a separate netcdf file from 1950-2016.
Due to no time axis information and after merging the files
by using CDO there is no error but still the time axis is
missing. So I need to insert the time axis for the whole
data from Jan-1950 to Dec-2016. I don't understand how to
insert the time axis I tried using
define axis/t/units=months/t="15-jan-1950:00:00"/calendar=360_days
tmonthly
let temp=temp[gt=tmonthly@asn]
but was unsuccessful. I hope there is a proper way to insert
the time axis for the data which are provided in separate
monthly files for each month. I am attaching only 2 files for
the experiment.
