| Abstract/Contents: | "Multispectral imagery with visible, near-infrared, and thermal wavebands was used to spatially estimate evapotranspiration (ET) in Berthoud, CO. The METRIC (Mapping Evapotranspiration at high Resolutions with Internal Calibration) energy balance model was used to estimate turf evapotranspiration from aerial multispectral imagery collected in 2011. The METRIC model was developed using Landsat satellite imagery but is adaptable to other satellite imagery with similar wavebands available. The METRIC model was also recently adapted for aerial imagery with limited reflective bands and a thermal band. Following adaptation for aerial imagery, the METRIC daily ET for turf at Berthoud, CO was compared to daily ET from 44 mini-turf weighing lysimeters on 31 August 2011. Combinations of ETo (short crop or grass reference ET) vs. ETr (alfalfa or tall crop reference ET) and alfalfa vs. turf cold pixel resulted in mean percent error of 6.20 and 6.48%, for ETo and turf cold pixel and ETo and alfalfa cold pixel, respectively. METRIC agreement with lysimeter data using ETr as the reference ET ranged from 37.5% to 48.5% mean percent error for turf and alfalfa cold pixels, respectively. On 19 July 2011, mean percent error of METRIC ET and lysimeter ET using ETo and a turf cold pixel was 6.15%. METRIC applications for turf require ETo as the reference ET in the model." |
