Wind resource data (file) at one height or multiple height? ONE SET or FOUR?

Hello , 

I want to ask that, for wind resource weather file, is it necessary to make FOUR SETS for temp, pressure, direction, wind speed?

Can i use only ONE SET for temp, pressure, direction, wind speed? (I have created the file but SAM / SAM library is not fetching / not working with ONE SET of four variables? 

Please guide me.   

Hi Hamza Ali,

Please see the "SRW format for wind" topic in SAM's Help system: samrepo.nrelcloud.org/help/weather_format_srw_wind.htm

If you would like me to help troubleshoot, please attach a copy of your wind data file.

Also, if you want to include an image in your forum post, please attach it as a file and then insert it into the message.

Best regards,
Paul.
