Hi, I'd like to know what method WEAP applies to estimate solar radiation when using the soil moisture method (not MABIA). Is it the hargreaves-samani equation?

WEAP uses equations from Chapter 4 of the Handbook of Hydrology for calculating net solar radiation, specifically equations 4.2.5, 4.2.6, 4.2.7 and 4.2.13.

You can view pages in the book on Amazon. Equations for solar radiation start on page 114 (search for "solar"): https://www.amazon.com/Handbook-Hydrology-David-Maidment/dp/0070397325#reader_0070397325

Thanks a lot Jack. I checked the handbook and the equations are very clear now.
