[ncl-talk] Subscript out of range

[Dennis Shea]

netcdf wrfout_d01 {
dimensions:
	Time = UNLIMITED ; // (97 currently)
	DateStrLen = 19 ;*	west_east = 30 ;
	south_north = 39 ;*
	bottom_top = 34 ;

---

The grid size is *(97,[34,] 39,30)*

fatal:*Subscript out of range, error in subscript #1*
fatal:An error occurred reading rain
fatal:["Execute.c":8637]:Execute: Error occurred at or near line 165 in
file meteo_abrapampa_b.ncl

1*65   arain_point  = rain(:,locY,locX)     ; subscript numbers 0,1,2*

---
 99    lat  = -22.721949
100   lon = -65.695454
101   llres = True
102   llres at ReturnInt = True   ; Return integer values
103   locij = *wrf_user_ll_to_ij
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_ij.shtml>(*a,
lon, lat, llres)
104   locij = locij - 1        ; array pointers in NCL space
105   locX = locij(0)
106   locY = locij(1)
107   print(locY)
108   print(locX)

Variable: *locY*
Type: integer
[snip]
(0)     *53*
*      <== This value exceeds the Y grid dimension size of 39*

The* wrf_user_ll_to_ij
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_ij.shtml>*
function documentation states:

"The return values will represent indexes in the WRF-ARW lon, lat model
domain and will be *1-based*. This is different from *wrf_user_ll_to_xy*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_xy.shtml>
in which the index values are 0-based.

Important note: if the index values from this function are later used as
indexes in NCL scripts, then a value of 1 needs to be deducted from the
values first"

Even subtracting one: * locY-1=52*   will exceed the Y grid size.

Further, the *wrf_user_ll_to_xy*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_xy.shtml>
documentation states

"*This function will be deprecated in NCL version 6.6.0**. *Use
*wrf_user_ll_to_xy*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_xy.shtml>
instead."


===

So use *wrf_user_ll_to_xy*
<http://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_ll_to_xy.shtml>

These functions were not written by NCL developers. If this does not work
matbe write to wrfhelp at ucar.edu


Good luck
