Combine gdas0p5 to overcome limit of 12 files

Post by weatherKat » November 27th, 2018, 2:34 am

Hi there,

I am trying to make my project as efficient as possible as I am doing a climatological analysis of parcel trajectories for 5 years at 7 locations for 5 levels. I have downloaded the daily files - example: 23rd Dec 2010 to 31st Jan 2011 (40 files) to provide 10 day trajectories for each day in January 2011. But I have not been able to yet get around the problem of HYSPLIT only allowing a maximum of 12 files. I have looked through each of the FAQ and the forum topics already posted but none offer a complete answer for me yet.
So how can I reduce my 40 files to 1 (or at least less than 12) so I may run 30 days worth of calculation in one go? I am using Windows and am capable of using either the GUI or a batch script.
Any help and quick responses are very appreciated! Cheers!

You can use the Windows "type" command to concatonate your files into one file, but make sure they are in the correct order (start to finish). See the following Forum topics:
