HYSPLIT Tutorial Videos
We recently added a series of HYSPLIT workshop videos that correspond with the current HYSPLIT Tutorial, both of which can be found at: https://www.ready.noaa.gov/HYSPLIT_Tutorials.php These series of videos (mp4) cover the same material as presented in the online HYSPLIT Tutorial. The instructor is...

Re: DEPOSITION
We do not supply the deposition parameters for radio-nuclides besides the ones defined in the GUI (Cs-137, I-131g, I-131p, etc) as these values are not well known.

Re: Back trajectories with user entered met data
The issue is that the program that uses the surface observation only creates a 250 x 250 km grid centered over your observation location. It is only designed to be used for very short range simulations since using one surface observation is not representative the farther you are away from the observ...

Re: HYSPLIT Data Interpolation
The meteorological data is linearly interpolated in both space and time during the calculation.

Re: HYSPLIT running period
You did not provide your CONTROL file but there is a limit of 12 meteorological filenames allowed in the CONTROL file, so you will have to concatenate your meteorological files. Search for concatenate in the forum and you will find similar questions/answers such as: https://hysplitbbs.arl.noaa.gov/v...

2018 HYSPLIT Europe Workshop
A 3-day PC/Mac HYSPLIT workshop will be given May 15-17, 2018, in Barcelona, Spain (a workshop is also planned for College Park, MD on June 12-15, 2018). The Barcelona workshop will be focused on the use of the most recent version of the model on the PC/Mac and its applications. This workshop is a s...

Re: The difference between two type of spacing in concentration modeling
Because the calculation of concentration is mass/volume and since your grid cell is larger in the first one, hence a larger volume, and therefore the concentration will be less assuming the mass is approximately the same in the grid box. Similarly for deposition, the calculation is mass/area and sin...
