A new approach for estimating northern peatland gross primary productivity using a satellite-sensor-derived chlorophyll index

, 2011
Carbon flux models that are largely driven by remotely sensed data can be used to estimate gross primary productivity (GPP) over large areas, but despite the importance of peatland ecosystems in the global carbon cycle, relatively little attention has ...

Regional estimation of daily to annual regional evapotranspiration with MODIS data in the Yellow River Delta wetland

, 2009
Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation from the water and the non-vegetated surfaces.

On quantifying soil water deficit of a partially wetted root zone by the response of canopy or leaf conductance

, 2004
Quantifying the soil water deficit (SWD) and its relation to canopy or leaf conductance is essential for application of the Penman-Monteith equation to water-stressed plants.
