Re: interpolate WRF 3km res. to match 4km res. NCEP Stage IV precip data

In order to get the difference plots, I would need to subtract the
regridded 4km wrfout files with the original NCEP stage IV data. However I
only want the NCEP Stg IV data that is within my domain for WRF. NCEP Stg
IV is the entire CONUS and more. How can I get just the array of data in
the WRF domain that I want? Before, I just plotted and zoomed in on the
data to look at the area that I wanted mpLimitMode= "corners" and
mpProjection = "LambertConformal" to essentially match my lambert conformal
WRF domain with specifying the 2 parallels and meridian.
