Interpretive Summary:

Technical Abstract: Recent advances support near-autonomous variable rate irrigation control systems. A novel energy balance application may provide complementary tools for in-season irrigation management. The BAITSSS model utilizes remotely sensed soil-canopy reflectance and available gridded soils and weather information to directly solve the two-layer energy balance for soil and canopy sources. The model provides 30-m spatial and hourly temporal resolution. Model performance has been evaluated against field lysimeters and eddy covariance systems in an irrigated cropland regime, subject to local and regional advection. Model application to water management districts has been evaluated against multi-year annual pumping records for regulated water rights. Feasibility and opportunity to extend application to in-season water management and control is addressed.
