Hi,
I have an ascii file with 3 columns: day, height in millibars and potential temperature. Everyday there are different number of height points at different intervals. I want to grid this data. As a simple example this is what I have done:
set data/ez/columns=3/variables="time,pres,theta" trial.dat
define axis/t=1:4:1 tax
define axis/z=100:1000:50 zax
let theta_grd=scat2gridgauss_zt(pres,time,theta,z[gz=zax],t[gt=tax],1,1,1,0)
When I give fill theta_grd I get the following error:
Bailing out of external function "scat2gridgauss_zt":
No data in scattered z, t points. F() data values must be defined on Z or T axis.
**ERROR: error in external function
I am sending an example data file as an attachment. I am using Ferret version 6.96. I went through the ferret archive but I am not sure what I have missed.
Thanks for any help.
Regards,
Priyanka
