SIREN data validation

How does "sen_makeweather_getmerra2" (by SIREN) is work and its data is valid?

Dear Hassan,

That program is part of the SIREN Toolkit, and downloads weather data from the NASA MERRA-2 database. Please refer to the SIREN website for more information about the data: https://sourceforge.net/projects/sensiren/.

Best regards,
Paul.

I'll contact you via the SAM Contact. In the meantime...

SIREN has been used in the creation of a number of reports to investigate renewable generation potential within the South West Interconnected System (SWIS) in the south-west of Western Australia. As part of this process, a verification of generation calculated by the use of weather files derived from MERRA-2 data along with the SAM models was achieved by comparing it with actual generation (SCADA) data for the SWIS renewable energy stations for 2014. Average correlation for 2014 was 0.77, varying from 0.70 to 0.83 for wind and 0.95 for the one utility scale PV farm on the SWIS network. Correlations for the years 2007 to 2015 average around 0.74 (0.70 to 0.76).

Kind regards

Angus
