Re: Confusion with results produced when changing sampling time interval and type
1. Certainly. I'm trying to use HYSPLIT to create atmospheric profiles of the release of a target chemical agent for use with a radiative transfer model. I'm modelling the detection of that agent using satellites, hence the need for a radiative transfer model and HYSPLIT to produce atmospheric profi...

Re: Confusion with results produced when changing sampling time interval and type
Having thought about this for a few days and also discussed with my supervisor, I have a few more questions I'd like to ask in addition to my previous one about computational particles: 1. Do you have any specific recommendations about which alternative models would be best to use if HYSPLIT turns o...

Re: Confusion with results produced when changing sampling time interval and type
Thank you very much for all the information. Looking into acquiring higher-resolution meteorology seems like a wise choice, as does switching to snapshots instead of averages. Having read your paper that you linked, I think I understand conceptually what you mean by computational particles, and that...

Re: Confusion with results produced when changing sampling time interval and type
I may have been. The ground level (which I assume is the extent of the deposition layer, I don't see why it wouldn't be?) concentrations do match, and the results above that altitude are about 15x smaller for the 15 minute average compared to the 1 minute, so those two points of confusion make a lot...

Re: Confusion with results produced when changing sampling time interval and type
My apologies for the late response! I was not notified by email that a reply had been posted, like I am used to, so I was not aware you had replied. Thank you for replying to my original post so swiftly. I don't seem to have SETUP.CFG files in my working directory, but I can supply the CONTROL and M...

Confusion with results produced when changing sampling time interval and type
I have been using HYSPLIT (the desktop client, to be specific) to retrieve a vertical profile of concentration of Sulphur Mustard gas for use in a radiative transfer model, the objective being to assess the capability of detecting this gas with a specific instrument. To collect test results I had in...

Re: Converting output of dispersion model into vertical profile of chemical concentration at different heights
Thank you very much for this advice, that is all very helpful! I'll be sure to download the client for HYSPLIT and see what progress I can make with that! Especially thank you for your explanation of the outputs in more detail and for recommending HYSPLIT for R, since I have some experience with R a...

Converting output of dispersion model into vertical profile of chemical concentration at different heights
I am looking at the detection of hazardous chemicals using satellites, and I'm running a simulation of atmospheric transmission/absorption to determine whether a given chemical could be detected using the Reference Forward Model, or RFM. One of the inputs this model requires is an atmospheric profil...
