Grid cell corners into WRF

[maR_Kus]

Hi All,

I just have a quick question on the grid cell corners: I realized the variables XLAT_C and XLONG_C are computed by geogrid but their values are never used by WRF during the simulations.

float XLAT_C(Time, south_north_stag, west_east_stag) ;
XLAT_C:FieldType = 104 ;
XLAT_C:MemoryOrder = "XY " ;
XLAT_C:units = "degrees latitude" ;
XLAT_C:description = "Latitude at grid cell corners" ;
XLAT_C:stagger = "CORNER" ;
XLAT_C:sr_x = 1 ;
XLAT_C:sr_y = 1 ;

float XLONG_C(Time, south_north_stag, west_east_stag) ;
XLONG_C:FieldType = 104 ;
XLONG_C:MemoryOrder = "XY " ;
XLONG_C:units = "degrees longitude" ;
XLONG_C:description = "Longitude at grid cell corners" ;
XLONG_C:stagger = "CORNER" ;
XLONG_C:sr_x = 1 ;
XLONG_C:sr_y = 1 ;

I was wondering how can I retrieve the corner latitudes and longitudes runtime?

Thanks into advance for help,
Markus
