How to get TMY3 data?

Hello,

I am trying to get the tmy3 data from nsrdb to use for SAM. In their website (https://nsrdb.nrel.gov/api-instructions) they have explained how to get weather/solar data for a particular year but how can I get tmy3 data? What changes should I make to the following?

url = 'http://developer.nrel.gov/api/solar/nsrdb_0512_download.csv?wkt=POINT({lon}%20{lat})&names={year}&leap_day={leap}&interval={interval}&utc={utc}&full_name={name}&email={email}&affiliation={affiliation}&mailing_list={mailing_list}&reason={reason}&api_key={api}&attributes=attr'.format(year=year, lat=lat, lon=lon, leap=leap_year, interval=interval, utc=utc, name=your_name, email=your_email, mailing_list=mailing_list, affiliation=your_affiliation, reason=reason_for_use, api=api_key, attr=attributes)

Thanks very much!

Dear Shahab,

To request a typical year file instead of a file for a specific year, use 'tmy' for the names parameter instead of a year.

Best regards,
Paul.

There is a slight error towards the end of the format string. 'attributes=attr' should be 'attributes={attr}' (curly braces are missing).

Kind regards

Dear Ammar Sakaji,

Your question seems to be about SAM rather than the SDK. SAM's weather file download feature downloads data from the NREL National Solar Radiation Database, which does not have data for locations in the Middle East. Please see the Weather Data page for more information about where to find weather data to use with SAM.

Best regards,
Paul.

I've done some work with creating weather files for SAM using NASA MERRA data. Feel free to contact me directly if you're interested in following this up.

Kind regards
