main contribution
Develop evaporation estimation methods that combine energy balance with aerodynamic processes.
Biographical or institutional source material ↗’s relevance in technology cases
The following cases cite their theories, methods or industry contributions; the historical basis does not mean that I directly participated in or invented modern products alone.
Priva Connext greenhouse environment control ↗
Temperature and humidity, radiation, ventilation and crop transpiration interact with each other. The sensor position and time delay determine the feedback quality; the overall number of air changes cannot represent all local microclimates.
Netafim NetBeat Digital Irrigation ↗
Soil water balance, crop evapotranspiration and pipe network hydraulics jointly determine irrigation needs; sensor representativeness and model calibration affect water saving and yield results.
