           I have a data file with uniform XY axis In Kilometers. What I need is to regrid this data into a regular XY geographical grid in degrees (not stereographic).
The lat-lon space to which the regriding to be done is not an issue. Any help is greatly appreciated

A plot of the data is attached.

Best Regards
Bijoy

dimensions:
        XGR = 511 ;
        YGR = 651 ;
variables:
        double XGR(XGR) ;
                XGR:units = "KM" ;
                XGR:point_spacing = "even" ;
                XGR:axis = "X" ;
        double YGR(YGR) ;
                YGR:units = "KM" ;
