Re: the numbers of emitors

Thank you. I mean that when I set krand to 1 I did not receive any txt file with results (when I set krand = 2 I receive txt file for every one hour of simulation, what means 24 files for 24 h run).
According to second question - I think one day (maybe sometimes longer, but max. 3), I do not need ...

Re: the numbers of emitors

Thank you! I did not think about it earlier.
I have two more questions, maybe someone would know answers for them.
1. What is krandr parameter? I have read in user guide that if the number of particles is greater than 5000, krand should be equal to 1. I have numpar greater than 5000 but when I set ...

the numbers of emitors

Hi,
I would like to ask if it is some limitation in case of the numbers of emitors in the emitimes file? I would like to run HYSPLIT with almost 70 000 point emitors, but the simulation takes so long (sometimes a few days for only one day of simulation, whereas I need to calculate almost three ...

krand

Hi,
I have a question about krand parameter. I want to run dispersion model with about 70 000 point emitors. To do that, there is a need to use huge number of particles. I have read in user guide, that when numpar is greater that 5000 krand should be equal to 1. I set this parameter to 1 but then ...

Re: EMITIMES

I don't use GUI. I'm working with scripts. So that's why I'm not sure which "version" should I use. I suppose that the first version - I mean something like this:
2018 06 01 09 1200 3
2018 06 01 09 00 1200 52.15 17.8 20.0 3567.0 1000.0 0.0
2018 06 01 09 00 1200 52.15 18.8 20.0 35697.0 1000.0 0.0 ...

EMITIMES

Hi,
I have a question about EMITIMES file. I have multiple source locations and I want to calculate dispersion for all of them - they have different lat and lon, rate, but the same height - I use EMITIMES file, but I'm not sure how to set it (how does exactly EMITIMES file work?), if it should be ...

inline-HYSPLIT multi run

Hello,
I would like to ask if it is possible to generate trajectories for many hours, for a few days, but for one location and one height, in one inline-HYSPLIT run? If it is possible, I'd be very grateful for answer: how to do it?
All the best,
Daria

I have moved this question into new topic [I would like to ask if it is possible to generate trajectories for many hours, for a few days, but for one location and one height, in one inline-HYSPLIT run? If it is possible, I'd be very grateful for answer: how to do it?]

Re: Trajectories in In-line HYSPLIT

Thank you very much! It works with time_step=60.
