[IDV #TTW-407940]: Profile from WRF Output



Stephanie,

First off sorry for the delayed response. We have been busy here with grant
proposals etc.

Before working with WRF data in the IDV please post-process the data through the
UPP. http://www.dtcenter.org/wrf-nmm/users/overview/upp_overview.php This will
ensure that you have a better experience working with WRF data from the IDV.

To your question...

Yes, it is possible to create vertical profiles at a single lat/lon.

In the IDV, please go to the Dashboard, Data Choosers Tab.

Go to the Files node under General (look to the left side of the dashboard).

Select your (possibly multiple) WRF output files.

Please select a Data Source Type of "Aggregate WRF netCDF grids by Time".

Click Add Source

Now you should be the Field Selector of the Dashboard.

Go to 3D grid, Derived, and select the field of interest (e.g., Flow Vectors).

In the Displays Panel, Select Probes, Vertical Profile.

Click Create Display.

As far as saving the probe data to CSV, unfortunately we do not have that
capability at present.

Please keep us up-to-date on your progress.

Best,

Unidata IDV Support

> Description of problem: Hello,
> 
> I am trying to create wind vector (and potential temperature) profiles over a 
> particular point (lat/lon) in my netcdf file which contains WRF output.  
> Ideally I woudl make one profile per 2 hour timestep over 12 hours.  My goal

> verify my model simulations.  I have figured out how to create time series 
> plots at a single height of different variables from my netcdf file at a 
> specified lat/lon and was able to export the data as a CSV file.  This is 
> hugely helpful so that I now have the exact data that will correspond to my 
> tower data at a single height.  Now my quetsion is how to create vertical 
> profiles at a single lat/lon in my netCDF file for each time step.  I would 
> like to compare these plots to vertical profiles from tether balloons for 
> verification.  I was attempting to create these profiles using the 
> instructions at this website: 
> https://www.unidata.ucar.edu/software/idv/docs/workshop/datadisplay
 s/profiler/TimeHeightDisplay.html.  I finally figured out that this example 
applies to 'wind profiler' data and not netcdf WRF output.  Ideally, I would 
also export the data in a CSV file, just like I did for the time series plots.

> Finally, my question is: Is there a way to create vertical profiles of my

> lat/lon for a specified timestamp?
