Evaluation of global observations-based evapotranspiration datasets and IPCC AR4 simulations
- States several recently developed products now provide the capacity to estimate ET at global scales
- Provides an overview and evaluation of 41 global land ET datasets for the 1989–1995 time period
- Evaluates the IPCC AR4 global climate model (GCM) simulations and provides an assessment of their capacity to reproduce flux behavior relative to observations-based products
- Finds the IPCC AR4 simulations, in their global average, show a smaller spread than the categories and groups that are partly based on observations, except for LSMs from the GSWP, which are driven with common forcing data
