I speculate there are no WRF meteogram scripts. The NCL example
demonstrates how to create a simple meteogram.

I am not sure what you mean by an "advanced" meteogram.
--- By definition, a meteogram consists of a time series of observations for different variables at a specific location and, generally, at a single level. Most commonly the surface level is visualized. There are no "meteogram standards", hence, meteograms take on a variety of forms. For a WRF type model, a simple approach might be as follows. [a] Specify the subscripts corresponding to a grid point closest to some station (eg: Istanbul, Turkey). [b] Read the various variables for that grid point. [c] The WRF "Times" variable is awkward to work with for plotting. NCL offers several functions that will transform this character variable to numeric forms. http://www.ncl.ucar.edu/Document/Functions/wrf.shtml Specifically: http://www.ncl.ucar.edu/Document/Functions/WRF_contributed/wrf_times_c.shtml So a thumb nail approach might be as follows. procedure metogram_WRF (time[*]:numeric,t[*],q[*],u[*],v[*],t[*],s[*],...) begin ; create various plots as per simple example. end begin ; MAIN program ii = ; index of desired longitude grid point jj = ; latitude kk= ; level diri = "./" fili = "wrf....nc" f = addfile (diri+fili, "r") Times = f->Times time = wrf_times_c( Times, 0 ) t = f->T(:,kk,jj,ii) read all the times qflx = f->QFX(:,kk,jj,ii) : meteogram_WRF(time, t,qflx,.....) end If meteogram_WRF was created as a function function meteogram_WRF (...) begin ; create various plots as per simple example. return(meteogram) end later plot = meteogram_WRF (...) You could overlay more information after returning draw(plot) frame(wks) Taking on a task like this can be tedious BUT it is often the best way to learn a computer language. My 1st NCL project was to develeop the skewT program. http://www.ncl.ucar.edu/Applications/skewt.shtml Good Luck Abdullah Kahraman wrote: > Hello all, > I am a beginner in NCL.
