Enhancing the Simplified Surface Energy Balance (SSEB) approach for estimating landscape ET: Validation with the METRIC model

Evapotranspiration (ET) can be derived from satellite data using surface energy balance principles. METRIC (Mapping EvapoTranspiration at high Resolution with Internalized Calibration) is one of the most widely used models available in the literature to estimate ET from satellite imagery. The Simplified Surface Energy Balance (SSEB) model is much easier and less expensive to implement. The main purpose of this research was to present an enhanced version of the Simplified Surface Energy Balance (SSEB) model and to evaluate its performance using the established METRIC model. In this study, SSEB and METRIC ET fractions were compared using 7 Landsat images acquired for south central Idaho during the 2003 growing season. The enhanced SSEB model compared well with the METRIC model output exhibiting an r² improvement from 0.83 to 0.90 in less complex topography (elevation less than 2000 m) and with an improvement of r² from 0.27 to 0.38 in more complex (mountain) areas with elevation greater than 2000 m. Independent evaluation showed that both models exhibited higher variation in complex topographic regions, although more with SSEB than with METRIC. The higher ET fraction variation in the complex mountainous regions highlighted the difficulty of capturing the radiation and heat transfer physics on steep slopes having variable aspect with the simple index model, and the need to conduct more research. However, the temporal consistency of the results suggests that the SSEB model can be used on a wide range of elevation (more successfully up 2000 m) to detect anomalies in space and time for water resources management and monitoring such as for drought early warning systems in data scarce regions. SSEB has a potential for operational agro-hydrologic applications to estimate ET with inputs of surface temperature, NDVI, DEM and reference ET.

春小麦子粒蛋白质积累和产量形成规律及施氮的调节作用

以春小麦不同品质类型为材料,研究子粒蛋白质和干物质积累规律。结果表明,春小麦灌浆期子粒蛋白质百分含量总的趋势均呈“Ｖ”型变化。但不同品质类型存在差异。高蛋白类型灌浆前期蛋白质含量下降缓慢,曲线波动小,高产类型则相反,高产高蛋白类型虽前期下降快,但后期回升速度也快,最终有较高的蛋白质含量。粒重在整个灌浆过程中均呈上升趋势,并在接近成熟时趋于稳定。等量氮肥分期施用,生育前期施氮有利于产量的形成,开花期叶面喷氮,在提高蛋白质含量的同时具有增加粒重的双重作用。不同品质类型小麦光合产物的生产和分配方向不同,高产高蛋白品种光合能力强,光合产物多,能够兼顾产量和蛋白质的同时增加。后期保持高光合速率和叶面积持续过程是高产、高蛋白类型的重要生理特性。
