The combination of these two, evapotranspiration, varies across regions and seasons, and is a significant fraction of the land surface water budget. Accurate forecasts and projections of evapotranspiration have applications in agriculture, water resource management and flood prediction.
This paper combines existing global evapotranspiration estimates to create a new global product with an observationally constrained estimate of uncertainty. It utilises the latest release of ground-based estimates to show that even point-based evapotranspiration estimates have information about much larger spatial scales.
