Abstract:In this study, a new parameterization scheme of evaporative fraction (EF) was developed from the contextual information of remotely sensed radiative surface temperature (T s ) and vegetation index (VI). In the traditional T s − V I triangle methods, the Priestley-Taylor parameter ∅ of each pixel was interpolated for each VI interval; in our proposed new parameterization scheme (NPS), it was performed for each isopiestic line of soil surface moisture. Specifically, ∅ of mixed pixels was determined as the weighted-average value of bare soil ∅ and full-cover vegetation ∅. The maximum T s of bare soil (T smax ) is the sole parameter needed as the constraint of the dry edge. This has not only bypassed the task involved in the determination of the maximum T s of fully vegetated surface (T cmax ), but also made it possible to reduce the reliance of the T s − V I triangle methods on the determination of the dry edge. Ground-based measurements taken during 21 days in 2004 were used to validate the EF retrievals. Results show that the accuracy achieved by the NPS is comparable to that achieved by the traditional T s − V I triangle methods. Therefore, the simplicity of the proposed new parameterization scheme does not compromise its accuracy in monitoring EF.

“…A number of studies have used EF to represent moisture conditions of ecosystems (Kurc and Small, 2004;Zhang et al, 2004;Suleiman and Crago, 2004). In addition, EF can be derived from remotely sensed vegetation indices and land surface temperature products from satellites such as AVHRR and MODIS (Venturini et al, 2004), a major advantage of this approach.…”

“…Therefore, the Terra sensor carried on the Moderate Resolution Imaging Spectroradiometer (MODIS), capable of observing ground objects of 0.44 km 2 in areal extent, is relatively preferable for rapid landslide detection. To overcome cloud contamination in frequent remote sensing, the maximum value composite (MVC) method has been widely used for Advanced Very High Resolution Radiometer (AVHRR) and MODIS products (Venturini et al 2004). The aim of the proposed approach is to detect landslides in cloudy mountains by means of an MVCbased analysis of MODIS images.…”
