[TRNSYS-users] TMY2 weather files

[pseudomino@gmx.com]

Hi,
 
 
I would like to know more about the .TMY2 weather files. When opening them in a text editor, they look pretty unreadable.
 
Maybe this is normal ? Is this a closed format ?
 
 
I cannot find documentation describing the format. For example, I wonder what the timestep is.
 
 
Thanks
