Hysplit Trajectory in Windows - issue with starting day
Posted: September 18th, 2016, 11:58 am
Hello, I am a home user of Hysplit, and I am running it on a PC laptop, Windows 32 bits (Vista).
In relation to the Gordon Bennett Gas Balloon competition, I would like to run Hysplit Trajectory. I know I can do it online, but I was only able to run the online model a few times, then I was unable to connect to the server again. Well I guess it's busy
Ok so I downloaded everything on my laptop and so far so good. I was able to get the meteorological model, etc.
First issue: I was unable to enter a later time than the meteorological model to start the calculation. I am using the gfslrf (2.5 degrees) and downloaded the latest available which is the 06 UTC (I thought I could get the 12 UTC, but it seems it was not available yet). Even if I enter time 22 UTC (same day, that is today) to start the model calculation, it does not work. I got error message that my starting time is -prior- to starting time of the meteorological model, which is not the case.
After reading the User Guide, I saw that if I leave all to '00' in the time and date field, the trajectory calculation would start at the same time as the meteorological model is starting. So I did that and I got a first result which seemed to make sense (it displayed in GSview properly).
I wanted to re-run the trajectory model with a longer time window, and here problems started: the starting day of the trajectory calculation is BLOCKED on the 28th of September! I tried everything (starting again, deleting the parameter files and starting from scratch, downloading again the meteorological model), nothing helped. I can't get the start date changed to anything else than 28th of September.
I am stuck now, so I hope that somebody can help me with this issue
Have a nice evening everybody,
Cheers
