Aim

Evaluation and intercomparison of existing land evapotranspiration products in the framework of the LandFlux initiative of the GEWEX Data and Assessment Panel (GDAP).

Considered datasets

• Remote sensing products
• Land surface modeling products
• Reanalysis data products (ERA-40, ERA-interim, NCEP, MERRA)
• Diagnostic estimates (Atmospheric water-balance estimates, terrestrial water-balance estimates)
• Ground observations (Flux measurements) and derived products
  

Data requirements (first phase)

• Global
• Monthly
• Available over time periods 1993-1995, 1989-1995, 2003-2006, 1989-2006, and/or 1950-2006

Benchmark synthesis products of evapotranspiration

The global benchmark synthesis products will be available from this homepage soon. The calculation and analyses of the products are described in Mueller et al. (2013). All available types of global datasets (see considered datasets) were considered.
