Re: Release number limits

I believe you are saying you did two runs using different number of particles. I suggest doing some more runs with more particles. In general when you have enough particles for that run the result will not change much when you add more particles.

Re: Dobson Units (DU) for air quality

Please contact the satellite SO2 people for an explanation of Dobson Units and to ask about the SO2 cloud top height in their products. We deal with the transport and dispersion.

Re: Unusual trajectories in Colombia (Nevado del Ruíz Volcano)

Have you looked at the wind fields or height contours using the 2D plotting programs at https://ready.arl.noaa.gov/READYamet.php to see if the trajectories look plausible? The trajectory is just a computation using the wind fields. The GDAS0P5 is not available for plotting but the GDAS1 is. You can ...

Re: Clustering Problem: "Error allocation time array: 1836008193"

Thanks for sending the set of trajectories. I was able to reproduce your error, though I'm not using Windows 10. In looking at one of the tdump (trajbwd...) files that you created using the SplitR package, the last two meteorological variables are written to the next line instead of staying on the l...
