The adjustment factors for HI and LAI of perennials

[Dhouha-ouerf]

I am trying to simulate some perennial crops and the LAI and HI adjustment are mandatory. However, I am not able to find any information. I would like to inquire where I could find the parameterization used to correct harvest index (HI) and leaf area index (LAI) for sub-optimum length of the effective growth cycle for the olive tree and other tree crops (αLAI, βLAI, αHI and βHI). Thank you in advance for your help.

Dear @Dhouha-ouerf,

Kindly refer to the GAEZ v4 Documentation, Page 64 for the correction of LAI and HI for perennial crops. Olive is a different case in GAEZ v4, which uses piecewise interpolation for the considered LGP duration, however this is not documented, and the equations are developed for general crops. So, I would suggest to use these parameterizations for the olive which I fully referred to GAEZ v3. Kindly substitute zeros with ones in the parameter setting. Hope these helps.
