[ncl-talk] overlay

[Ehsan Taghizadeh]

 Dear Mary
Thank you very much for your helpful reply. I used "wrf_gsn_5.ncl" fromhttps://www.ncl.ucar.edu/Applications/wrfgsn.shtml
and added shapefiles to "map".I need two more helps now, and I'll be thankful if I could have any suggestion again:
1- where should I add boundaries at mpOutlineBoundarySets  = "National"@mpDataSetName            = "Earth..4"   ; 1 through 4

I've tried to add them to "res_map", but it seems doesn't work!
2- I've used "2m Relative Humidity" and contoured it. How could I fill it just for RH>80% (just one color)
If it helps I could attach the script. However I've attached one sample of output.(Sorry for direct email. It was unintended)SincerelyEhsan

 Ehsan,
Please see example wrf_gsn_5.ncl and wrf_nogsn_5.ncl at
https://www.ncl.ucar.edu/Applications/wrfgsn.shtml

It shows you how to overlay several WRF plots on top of each other, using WRF plotting functions, and gsn_csm plotting functions.
Adding shapefile outlines should be done to the map plot, and I believe there's an example on the same page.

Hi,I have some basic problems about overlaying different quantities of WRF, for a few months and unfortunately, until now I couldn't solve it and I'll be thankful if I could have any help for this.I saw "https://www.ncl.ucar.edu/ Training/Tutorials/WRF_Users_ Workshop/WRF_NCL.shtml", (wrf_demo_plot_tc_gsn_ shapefiles.ncl). It is near to what if want. I just want to add some quantities to it and overlay on it"uv10 = wrf_user_getvar(f0,"uvmet10", it);  u at 10 m, mass point rh2 = wrf_user_getvar(f,"rh2",0);        2m Relative Humidity (%)

I mean overlay of "uv10" as vector and "rh2" as contour, on "terrain" and "shapefiles".I've written some scripts and I could send it. I want to use "gsn_csm_countour", "gsn_csm_vector", and "overlay" for related quantities.I hear from Mary Haley "I recommend that people use the gsn_csm_contour_map function for plotting WRF data when they need to add a lot of customization to the plot", for that reason I pointed "gsn".
I'll be thankful for any help. As I said above I have this problem for a few months, before August, when I tried to plot a cross-section of WRF quantities with overlaying them. For now, I just want vector and contour, not a cross-section.
SincerelyEhsan
