Hi All
I want to perform a linear interpolation on GCM data along
the time axis. The existing data set is organised
as separate files representing snapshots at 5 day intervals and
I've created a Descriptor file to work with the data within
Ferret. I want to interpolate these results from 5 day to 1 day.
From what I can gather this should be a rather trivial task,
however I can't seem to get my code to work. When I plot the
interpolated results the figure indicates that there is no valid
data in the interpolated data set.
!--------------------------
use GCM_data.DES
LET var_5day = temp ! for example
! interpolate data along new time axis
DEFINE AXIS/t=25-JUN-1992:31-DEC-1999:1/UNITS=days tax_1day
LET var_1day = var_5day[Gt=tax_1day@LIN]
!-------------------------
The DES file used to import the data has a time axis
at exactly 5 day intervals and I want the new axis to
interpolate at 1 day intervals. However the output data set has
no valid data.
Thanks
in advance for you help,
