[ncl-talk] gc_inout

[Md. Jalal Uddin]

Hi Rick,

Thanks for your sound explanation. Please help.

slat      = (/ 7.5, 8.5, 9.5 /)
slon      = (/88,88.5,89/)
srad      = (/ 500 /)
srad_unit = 1
N         = 180
opt       = False
circle    = geolocation_circle(slat, slon, srad, srad_unit, N, opt)
circle_lat = circle[0]
circle_lon = circle[1]

Now, I tried to mask my data within circle_lat and lon.
 f2  = addfile("all_mar.nc", "r")
 prc2 =f2->pre
tcavgmar = dim_avg_n_Wrap(prc2,0)

lat = new(3,"float")
lon = new(3,"float")

in_circle = gc_inout(circle_lat,circle_lon,lat,lon)
copy_VarMeta(circle_lat,in_circle)
martrmm  = where(in_circle,tcavgmar,tcavgmar at _FillValue)

errors:

(0)     totype: warning: cannot convert input variable type <float> to
type: <logical>
(0)        The original type: <float> will be returned.
fatal:where: condition variable (parameter 0) dimension mismatch with
parameter 1
