Graphics: NCL - Example

Now also available is a script that will read the namelist.wps file directly, so no need to duplicate information. (New - October 15, 2009)

A function has been built into NCL to preview where a potential domain will be placed (similar to plotgrids.exe from WPS).

This functionality is available in NCL version 5.0.1, but is currently still experimental.

The function used to generate these plots is called wrf_wps_dom. This function requires a WorkStation and 3 lists of resources - map resources, line resources and text resources.

The map resources are similar to domain information provided in WPS. Information for multiple domains may be provided. The required map resources are (for details view one of the examples below):
max_dom; parent_id; parent_grid_ratio; i_parent_start; j_parent_start; e_we; e_sn; dx; dy; map_proj; ref_lat; ref_lon; truelat1; truelat2; stand_lon; (pole_laet & pole_long are also required for rotated lat-lon domains)

Map resources are also used to set background and map line colors.

Line and Text resources are used for the nests.
