[ncl-talk] rcm2rgrid issue

[Dennis Shea]

*http://www.ncl.ucar.edu/Document/Functions/Contributed/rcm2rgrid_Wrap.shtml*
<http://www.ncl.ucar.edu/Document/Functions/Contributed/rcm2rgrid_Wrap.shtml>

and *rcm2rgrid*
<http://www.ncl.ucar.edu/Document/Functions/Built-in/rcm2rgrid.shtml>
require that the destination (rectilinear) grid have the coordinates
(lat[*] and lon[*])  in *ascending order*.

You rectilinear grid looks like it is in descending order:  *latitude:
[49.5..-19.5]*

*f = addfile("EIN5.soilT.0-7cm.JJASmean.1982-2016.remap.nc
<http://EIN5.soilT.0-7cm.JJASmean.1982-2016.remap.nc>","r")*
*x = f->SOIL*
*printVarSummary(x)*

*print("========")*


*x = x(::-1,:)    *
*printVarSummary(x)*
*print("========")*

  xgrd  = *rcm2rgrid*(lat2d,lon2d,*x,x&lat,x&lon*,0)
