I have a dual-doppler radar analysis of the landfall of Hurricane Florence. It contains a grid of 200x175 points, and the X and Y coordinates are distances in meters from one of the two radar towers. The grid has a resolution of 1km, i.e. there is a radar observation recorded every 1000m. The radar analysis files are in netCDF format, and they do not contain latitude and longitude, so I am unsure how to plot it on a map with coastlines and state borders. The (X,Y) point (0,0) is the only known latitude and longitude (the same as one of the radar stations: 33.9892, -78.4291). I would like to use this radar analysis to help evaluate/validate 10m wind speeds that I get from a WRF run.

Here is my question/problem: Is there a way that I could convert a 200x175 grid of distances (dx,dy) reported from one reference latitude and longitude, into a grid of latitude and longitude points that I can then compare with my WRF output? Alternatively, is there a relatively easy way to convert WRF output into a grid of distances, in meters, from one reference latitude and longitude, that I can then use to compare with my radar analysis?

Thank you,

Ted
