How to run back-trajectories on a long period without having simultaneously all the meteorological files on my PC?
Posted: June 25th, 2020, 1:50 pm
I am trying to estimate back-trajectories (72h) on a long period (5-10 years), at least one per day. I do this to see if there is a correlation with the concentration of air pollutants detected in my area in order to estimate possible origin areas for these pollutants.
Until now I used the reanalysis meteorological files (2.5 degrees), but I would like to be more accurate as possible with the grid resolution. At the same time, I can’t have terabytes of meteorological files on my PC for this long period: is there a way to use better resolution meteorological files (e.g. GDAS 1° or gfps0.25) without having simultaneously all of these files on my PC?
I thought that it would be great to have a script that download few meteo files, run part of the trajectories, delete the meteo files, download new meteo files,...and so on. But I am not that expert (euphemism) in batch scripting, and in any case I am open to suggestions.
Thanks!
