Evaporation Using Planet Cubesats and the PT-JPL Model: A Precision Agriculture ApplicationB. AragonR. HouborgK. TuJ. FisherM. Mccabe
To fill this gap, we introduce two RS vegetation variables beyond NDVI into the PT-JPL model and investigate the influence of different vegetation input schemes on ET estimates. Specifically, we first combine vegetation variables estimated by empirical methods and RS products into four vegetation inpu...
该模型利用卫星遥感数据和气象数据,包括地表温度、植被覆盖、降水量等,通过复杂的数学计算和物理过程模拟,估算陆地表面的蒸发和植被蒸腾量。PT_JPL_global模型能够提供全球范围内高分辨率的蒸发蒸腾数据,为水资源管理、农业生产、气候变化研究等提供重要参考。Global Terrestrial Evapotranspiration via PT_JPL model ...
In a case study in the Driftless Area of Wisconsin, the models were also compared with a predictive model based on existing soil survey. The results showed that regression with environmental variables works well for areas where the soil-terrain relationship is relatively simple but regression with ...
The widely used Priestley-Taylor Jet Propulsion Laboratory (PT-JPL) model has the most potential to operationally simulate ET over large areas, but its inability to fully track soil evaporation dynamics using atmospheric humidity limits its application in agroecosystems. In this study, we isolated ...
In this study, we compared soil evaporation parameterized with optical and thermal indices derived from MODIS to RH‐based soil evaporation as implemented in the Priestley Taylor‐Jet Propulsion Laboratory (PT‐JPL) model. We evaluated the parameterizations by subtracting PT‐JPL transpiration from ...
