Modeling stomatal conductance in the earth system: linking leaf water-use efficiency and water transport along the soil–plant–atmosphere continuum
earth system leaf water-use effi ciency
2014/12/19
The Ball–Berry stomatal conductance model is
commonly used in earth system models to simulate biotic
regulation of evapotranspiration. However, the dependence
of stomatal conductance (gs) on vapor ...

Evaluation of a Global Vegetation Model using time series of satellite vegetation indices
Global Vegetation satellite vegetation indices
2014/12/9
Atmospheric CO2 drives most of the greenhouse
effect increase. One major uncertainty on the future rate of
increase of CO2 in the atmosphere is the impact of the anticipated climate change on the ve...
