Dear NCL'ers,<br>
I have a variable in cylindrical (r, theta, z) coordinates where the dz is<br>
varying as a function of z. I am interested in performing a volume average<br>
where the radial, as well as the vertical average, comprises dealing with<br>
elements of varying size. What is the most efficient way of performing the<br>
triple integral necessary for the volume averaging of this variable in<br>
cylindrical coordinates?<br>
<br>
I am sure many of you have dealt with this before.<br>
<br>
Sincerely,<br>
Prashanth<br>

I am trying to get time series at given locations from several WRF output files, e.g. 48H forecast temperature at 850hPa. Each file contains a day's model run. I have used ncl for years by adapting existing scripts, without really understanding. One issue I have difficulty with is getting variables from a file, especially WRF output.I thought the script to get a time series at 15S, 30E would be as simple as the one below. I am able to print the varsummary, but printing x tells me that "a is not a valid file reference.I would appreciate ant assistance.begin<br>
files = systemfunc("ls -1 data/wrfout_d01_2020*") + ".nc"<br>
? a = addfiles(files,"r")<br>
<br>
? ListSetType (a, "cat")????????? ; concatenate (=default)<br>
? tc = wrf_user_getvar(a,"tc",0)<br>
? printVarSummary (tc)<br>
<br>
? x = a->T2(0,{850},{-15},{30})<br>

HI Zilore,<br>
<br>
I think the issue is that addfiles() return a *list* of filevars, where<br>
addfile returns a single filevar. Lists are indexed with [ ] notation;<br>
perhaps something like this will work:<br>
<br>
x = a[:]->T2(0,{850},{-15},{30})<br>

Dear ncl team<br>
I upgraded my operating system to Debian GNU/Linux 10 buster<br>
<br>
This new Debian has GNU Fortran (Debian 8.3.0-6) 8.3.0 installed<br>
<br>
Now, when I run ncl it gives me the error:<br>
ncl: error while loading shared libraries: libgfortran.so.3: cannot open shared object file: No such file or directory<br>
<br>
The new Debian has libgfortran.so.5<br>
<br>
/usr/lib/x86_64-linux-gnu/libgfortran.so.5<br>
<br>
so I upgraded ncl using to the last precompiled binary<br>
<br>
ncl_ncarg-6.6.2-Debian9.8_64bit_nodap_gnu630.tar.gz<br>
<br>
bu I got the same error.<br>
<br>
I can I use ncl in Debian 10?<br>
<br>
Many Thanks<br>
Francesco<br>

Perhaps do a printVarSummary(a[0]->T2) ; it sounds like its not the shape<br>
you think it might/should be; i.e. 3D vs 4D<br>

Hi<br>
I am trying to derive the diagram of extinction coefficient and particulate<br>
depolarization ratio from calipso level 2 layer and profile products for<br>
aerosols. I would appreciate if anybody can tell me how can I find any<br>
example code in this regard.<br>
Thanks<br>

Hi Francesco<br>
<br>
Have you checked if your Debian distribution has a "compat" (compatibility)<br>
package for gfortran/libgfortran<br>
between libgfortran.5 and libgfortran.3 ?<br>
Apt-get may have a way to check if it is available.<br>
I don't use Debian, but CentOS-7, which has an older kernel and older<br>
libraries.<br>
However, I have libgfortran.3 along with a "compat" package that provides<br>
compatibility with libgfortran.1, for example.<br>
<br>
An alternative is to install NCL using Anaconda Python.<br>
This is currently the recommended method (argh!):<br>
<a href="https://www.ncl.ucar.edu/Download/" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Download/</a><br>
That is self-contained, doesn't depend on the system libraries.<br>
In my experience it has other problems, particularly a sensitive dependency<br>
on other Anaconda Python packages<br>
that change by the hour, and don't give a damn to backward compatibility,<br>
which can easily break functionality.<br>
So, if you install this way, be careful with any conda packages updates, or<br>
simply don't update.<br>
<br>
I hope this helps,<br>
Gus Correa<br>

Sorry Rick I put in a surface variable T2 which only 3 coordinates, so I put "x = a[:]->T2(0,{-15},{30})". Now I am getting error of coordinates west-east and south-north not having? associated coordinate variables. I have seen this error before. I will find out how to get out of it <br>

HI Zilore,<br>
I think the issue is that addfiles() return a *list* of filevars, where addfile returns a single filevar.? Lists are indexed with [ ] notation; perhaps something like this will work:<br>
? x = a[:]->T2(0,{850},{-15},{30})<br>

T2 is a three dimensional variable. Also, T2 is the two meter temperature.<br>
<br>
You want tc or tk (see:<br>
<a href="https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml</a>).<br>
<br>
Could you please explain how you are interpolating to 850 mb? There is a<br>
WRF program to do this, and I am not sure how the indexing you are using<br>
works. How are you indexing the 48 time slot? WRF has a program to list<br>
times, and you can match the time you want to the listed times to find the<br>
index.<br>

Just to clarify: T2 is 2 dimensional. It is written every time step as<br>
such. Tk and Tc are three dimensional.<br>

Barry,My intention is to have RH and U, V time series. That's what I had in mind when I put 48. T2 only has time, lon ,lat. I have several daily output files, and I want an n-day series of 48 hour forecasts of T2<br>

T2 is a three dimensional variable.? Also, T2 is the two meter temperature.?<br>
You want tc or tk (see:?<a href="https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml" rel="noreferrer" target="_blank">https://www.ncl.ucar.edu/Document/Functions/WRF_arw/wrf_user_getvar.shtml</a>).<br>
Could you please explain how you are interpolating to 850 mb?? There is a WRF program to do this, and I am not sure how the indexing you are using works. How are you indexing the 48 time slot?? WRF has a program to list times, and you can match the time you want to the listed times to find the index.<br>

Sorry Rick I put in a surface variable T2 which only 3 coordinates, so I put "x = a[:]->T2(0,{-15},{30})". Now I am getting error of coordinates west-east and south-north not having? associated coordinate variables. I have seen this error before. I will find out how to get out of it <br>

HI Zilore,<br>
I think the issue is that addfiles() return a *list* of filevars, where addfile returns a single filevar.? Lists are indexed with [ ] notation; perhaps something like this will work:<br>
? x = a[:]->T2(0,{850},{-15},{30})<br>

If you know when these values occur within the time series, then you can<br>
index them quite easily.<br>
<br>
Why don't you use wrf_user_getvar and then the wrf interpolation program.<br>
<br>
If you want them at a specific point, I think you know how to do this.<br>
There is also a get location program<br>

I am plotting map of pre anomalies 1998-2018 with reference to the base<br>
period 1981-2010 at decadal time scale. I am getting the headed above<br>
warning along with no contours in the resulting plot. I think the problem<br>
occur at line 56 which I have used "wgt_runave_n_Wrap" function for<br>
filtering.<br>
1) I have checked my values to plot, they are all not missing values.<br>
2) the coordinate variables of y (filtered values) are also okay.<br>
<br>
I have attached scrip and resulting plot for your reference. I am using CRU<br>
pre data that are too big to attach along with this mail.<br>

hi there, Dickson, <br>
<br>
1) could be that the way you?ve set your contour levels does not match the values of the field you want to plot.<br>
In that regard, what is the output of the command line:<br>
<br>
printMinMax(y, 0)<br>
<br>
[line 62 in your script]<br>
<br>
2) but I also note that you?ve set:<br>
<br>
res2@mpLandFillColor = ?white"<br>
<br>
[twice, at lines 123 and 131]<br>
<br>
What happens if you comment these two lines out?<br>
<br>
warm regards, alessandra<br>

Thanks I have looked at examples of wrf_user_ll_to_ij, It does not help. Let me clarify two things1. I used tc just to test that I can at least access tc, but that syntax does not give me tc at a specific location.2. When I talk of a specific location, I do not need interpolation. I know WRF will give me the value at the nearest grid location. That is enough for me. My core problem is: how do I put it to get one value, instead of the whole grid?<br>

If you know when these values occur within the time series, then you can index them quite easily.<br>
Why don't you use wrf_user_getvar and then the wrf interpolation program.<br>
If you want them at a specific point, I think you know how to do this.? There is also a get location program<br>

Could you please explain how you are interpolating to 850 mb?? There is a WRF program to do this, and I am not sure how the indexing you are using works. How are you indexing the 48 time slot?? WRF has a program to list times, and you can match the time you want to the listed times to find the index.<br>

HI Zilore,<br>
I think the issue is that addfiles() return a *list* of filevars, where addfile returns a single filevar.? Lists are indexed with [ ] notation; perhaps something like this will work:<br>
? x = a[:]->T2(0,{850},{-15},{30})<br>

Since WRF grid is a 2D grid (i.e. curvilinear grid), you would need to use<br>
special sub-setting function/s. See example 2 on the following page:<br>
