1)Evaluate the effectiveness of the new stand-alone surface renewal (SR) method to accurately quantify almond orchard use. 2)Compare stress indices from SR with several other to determine best combo for almonds. 3)Continue efforts to develop infrared temperature radiometers (IRT) based measurements of evapotranspiration (ET) using the surface renewal technique. 4)Compare IRT and aerial imagery derived indices with direct physiological measurements made from 2013-2017 in an Almond irrigation trial located in Kern County, CA.
Compare water use/stress of almond trees growing in a weighing lysimeter with estimates from our new SR method, IRT sensors, and traditional physiological analyses. Further develop our efforts on testing whether IRTs work effectively in deriving water use from the canopies. Utilize existing datasets from farm advisor cooperators to explore the effectiveness of the commercial SR sensors.
