NCL scripts for plotting WRF data

Note: the scripts on this page are meant to be used as a set of step-by-step examples for the NCL Workshop being held at ARSC/UAF, March 11-15, 2013. Some of these scripts are very basic and not appropriate for real-world use. If you want to use the scripts on this page, we recommend using the ones with the higher numbers; for example, "wrf_gsn_t_8.ncl" rather than "wrf_gsn_t_1.ncl".

Sean Egan provided NetCDF file used for these plots, "wrfout_d01_2008-08-09_00:00:00.nc".

This set of scripts compares three ways of generating the same plot: using wrf_xxxx plotting scripts, using gsn_csm_xxxx plotting scripts, and using PyNGL and PyNIO.
wrf_xxxx	gsn_csm_xxxx	PyNGL/PyNIO
wrf_hgt.ncl	wrf_gsn_hgt_9.ncl	wrf_ngl_hgt.py

This set of examples plots temperature from a WRF file.

wrf_ll_to_ij.ncl

This set of examples plots temperature from a WRF file. It compares the wrf_xxxx scripts with the gsn_csm_xxxx scripts. The wrf_t_n.ncl scripts use wrf_xxxx plotting functions, and the wrf_gsn_t_n.ncl scripts use gsn_csm_xxxx plotting functions,
wrf_t_1.ncl	wrf_gsn_t_1.ncl	wrf_t_2.ncl	wrf_gsn_t_2.ncl
wrf_t_3.ncl	wrf_gsn_t_3.ncl	No more wrf_xxxx versions of this script.
wrf_gsn_t_4.ncl	wrf_gsn_t_5.ncl	wrf_gsn_t_6.ncl	wrf_gsn_t_7.ncl
wrf_gsn_t_8.ncl	wrf_gsn_t_9.ncl

This example plots wind barbs over temperature over sea level pressure over a map. It compares the wrf_xxxx scripts with the gsn_csm_xxxx scripts.
wrf_xxxx	gsn_csm_xxxx
wrf_t_slp_uv.ncl	wrf_gsn_t_slp_uv.ncl

This set of examples plots height from a WRF file. It only uses gsn_csm_xxxx plotting scripts. The last example shows how to add shapefile outlines.
wrf_gsn_hgt_1.ncl	wrf_gsn_hgt_2.ncl	wrf_gsn_hgt_3.ncl	wrf_gsn_hgt_4.ncl
wrf_gsn_hgt_5.ncl	wrf_gsn_hgt_6.ncl	wrf_gsn_hgt_7.ncl	wrf_gsn_hgt_8.ncl
wrf_gsn_hgt_9.ncl	wrf_gsn_hgt_10.ncl	wrf_gsn_hgt_11.ncl
