Re: Instantaneous wind fields as input?

Thank you very much for this very useful response! We will be looking at horizontal scales that resolve or partly resolve convection 2.5 - 5km grid box in the tropics. How would you recommend dealing with convection in that case / does this have affects on which turbulence parameterization is most a...

Instantaneous wind fields as input?

Hi, so far I have always used gridded meteorological data with mean wind values, e.g. averaged over a 3 hourly time-period. Now we have gridded meteorological simulation data with 3-hourly temporal resolution and instantaneous wind velocities. I am wondering how to approach this, e.g. how to estimat...

Re: 3D visualization of Hysplit output?

Hi, very helpful to have the reader for the PARDUMP file as a start. Thanks again. I ran one of the Hysplit tutorial examples (the Iceland volcano) and converted the particle and concentration output (PARDUMP, cdump) such that it can be processed by the visualization software Met3D. See attached scr...

Re: 3D visualization of Hysplit output?

Hi, thanks for the response! I am working in a research Group that develops a tool for interactive 3-D visualization of gridded meteorological data and trajectories (called "Met3D"; Visual Data Analysis Group, University of Hamburg) and was going to try and process some of the Hysplit output such th...

Re: Code parallelization

very interesting. I am thinking about trying to build a GPU based interactive particle simulator and this will be a good start. Thanks for the link.

which model results are available as output per default?

Which model outputs can be requested by the user? For example, I would be interested in looking at: -meteorological data or other "state-variables" at the position of trajectories / particles in dispersion runs (e.g. temperature, etc.; but e.g. also travel time and "particle mass" - used for calcula...

Code availability?

Is the model code available for experimental, user-defined modifications for research purposes (which licenses)?
