I saw your video on the new particle data reader in Vapor 3.5.0. What model is outputting the particle data? In other words, what model is this supposed to be for?

Hi,

The data was output by this python script:  
[https://github.com/NCAR/VAPOR/blob/main/share/examples/generateExampleDCP.py](https://github.com/NCAR/VAPOR/blob/main/share/examples/generateExampleDCP.py)

It shows how to output your particle data from any model.

You can find a specification for the data format here:
