Re: [ferret_users] geostropic currents
Dear Mahesh,
I dont know why ferret takes a different grid. Had you tried with yy = y[g=grid_0001]

Subject: [ferret_users] geostropic currents
Dear friends,
I am computing geostropic currents using Aviso altimetry. it plots the currents, please see the figure below....
here I am also attaching the script .....
the ferret script ...
can data/all
can viewport
use dt_ref_med_merged_madt_h_20090610_20090610_20100602.nc !(aviso ssh)
let g=9.8
let pi=3.141
let omega = 0.729e-4
let yy = y[g=GLZ2] !( please note that this 'GLZ2' is coming from ferret
let f=2.0*omega*sin(yy*pi/180.0)
let ssh=GRID_0001
let ug = -1.0*(g/f)*ssh[y=@ddc] !(centered difference scheme is used)
let vg = (g/f)*ssh[x=@ddc]!(centered difference scheme is used)
!plot geostropic winds
vec/l=1/xskip=4/yskip=4/nolab ug,vg
go land
!-------------------------------------------------------------------------------------------------------------
please tell why currents are looks like.....
thanks
regards
mahesh
