Reference evapotranspiration of screenhouse‐grown crops

The reference evapotranspiration E ref was measured under three screenhouses and compared to outside E ref .The reduction with respect to outside E ref was quantified by means of two factors,  rad and  adv . rad was found to depend linearly on transmittance (), and  adv on wind ratio ().A model was proposed for screenhouse E ref based on outside weather data,  and 
