Weather Data


I am trying to use SAM to design PV solar systems but I confront the problem of inserting weather date as I am living in Middle east – Yemen.
I would highly appreciate any advice to create the file or how to download & use data provided by NASA.

Sorry, you may have had this inquiry many times before, but I don’t have much time to search in this topic.

Many thanks

The SIREN Toolkit includes an executable program called sam_makeweather_getmerra2.exe that generates a SAM CSV weather file from NASA data. The project is hosted at Sourceforge:

You can find links to this and other data sources on the Weather Data page of the SAM website:
