I am wanting to work through the "Simulating a Polarimetric Radar Return for Weather Observation" example on MATHWORKS (https://www.mathworks.com/help/radar/ug/simulating-a-polarimetric-radar-return-for-weather-observation.html). I cannot figure out where NEXRAD_Parameters.mat, NEXRAD_pattern.mat, or NEXRAD_data.mat. I was able to find compressed data from here:https://www.ncdc.noaa.gov/nexradinv/choosesite.jsp but cannot get it into a mat file which I can use. Please help get these NEXRAD_Parameters, NEXRAD_pattern and NEXRAD_data in a way I can continue on with the example. Thanks!

在 MATLAB Online 中打开

Hello Ryan,

MATLAB ships all the necessary files required to run any example right along with the software. To find the data files, please enter the command:

openExample('radar/WeatherRadarExample')

in the MATLAB terminal.

This command can also be found in the MATLAB documentation pages at this location:

Hope this helps!

So you did this manually once, is there a function to read any downloaded Level II data file? The Web Map Server is way beyond complicated for what I want. I can find some Python code (pyart) that reads them, so my alternate path is to try to get that to work.
