Hi everyone! I'm using hysplit as part of a project to model tephra concentration in the air and I have a bunch of particle size/density/sphericity data I collected from tephra samples. I want to use this data as an input for the concentration model, how would I do this/is it possible? I looked through the manual but struggled to find what I should do. Sorry if there is an obvious solution, I am still new to this!
Regards,
Olivia
Utilizing Particle Size Characteristics
Re: Utilizing Particle Size Characteristics
Hello!
You can define different 'species' in HYSPLIT. Each species (pollutant) has it's own emission rate, emission duration, release start time,

Each one also has it's own deposition and gravitational settling parameters

Below is an example control file for a simulation with four different types of particles.
