| description abstract | Thermal images from an aircraft-mounted scanner are used to evaluate the effectiveness of crop-freeze protection devices. Data from flights made while using fuel oil heaters, a wind machine and an undercanopy irrigation system are compared. Results show that the overall protection provided by irrigation (?2°C) is comparable to the less energy-efficient heater-wind machine combination. Protection provided by the wind machine alone (?1°C) was found to decrease linearly with distance from the machine by ?1°C (100 m)?1. The flights were made over a 1.5 hectare citrus grove at an altitude of 450 m with an 8?14 ?m detector. General meteorological conditions during the experiments, conducted during the nighttime, were cold (? ?6°C) and calm with clear skies. | |
