WRF

Some of the functions below are built into NCL, while some of them are part of the WRFUserARW.ncl script, which is a library of functions and procedures written to help users plot ARW WRF model data.

More information on using NCL with ARW WRF is available from the ARW WRF Users Web site at http://www.mmm.ucar.edu/wrf/OnLineTutorial/Graphics/NCL/.

WRF-related questions should be sent to wrfhelp@ucar.edu.

wrf_contour Creates a contour plot from ARW WRF model output.
wrf_interp_1d Linearly interpolates a one-dimensional variable in the vertical.
wrf_interp_2d_xy Extracts a cross section from a given input field.
wrf_interp_3d_z Interpolates to a specified pressure/height level.
wrf_latlon_to_ij Finds the nearest model grid indices (i,j) to the specific location(s) in latitude and longitude.
