I am aware that CERES wheat converts inputs of solar radiation to Photosynthetically active radiation (PPFD) by multiplyinhg the radiation values by the constant 0.5 assuming that 50% of the incoming solar radiation is in the photsynthetically active range. Does anyone know how CROPGRO model does this?
