Other claims from this paper (8)
- Method / resource Remote sensing energy fluxes closely matched measured fluxes and predicted air temperature at the system locations.
- Observation The system air temperature was representative of only half of each field at overpass time.
- Observation The wheat field had an air temperature variation of 3 C.
- Observation The cotton field had an air temperature variation of 6 C.
- Method / resource Single-station reference evapotranspiration could overestimate crop water needs in some field areas.
- Method / resource Single-station reference evapotranspiration could underestimate crop water needs in other field areas.
- Method / resource The tested SEBAL DT method requires substituting average irrigated crop canopy temperature for the coldest pixel.
- Recommendation The authors recommend investigating spatial estimation of ETo variables with remote sensing and GIS.
