Rescaling the complementary relationship for land surface evaporation

Rescaling the complementary relationship for land surface evaporation

Recent research into the complementary relationship (CR) between actual and apparent potential evaporation has resulted in numerous alternative forms for the CR. Inspired by Brutsaert (2015), who derived a general CR in the form y5 function (x), where x is the ratio of potential evaporation to apparent potential evaporation and y is the ratio of actual to apparent potential evaporation, an equa...

Reply to comment by Ma and Zhang on ‘‘Rescaling the complementary relationship for land surface evaporation’’

Ma and Zhang (2017) note a concern they have with our rescaled Complementary Relationship (CR) for land surface evaporation when daily average wind speeds are very low (perhaps less than 1 m/s). We discuss conditions and specific formulations that lead to this concern, but ultimately argue that under these conditions, a key assumption behind the CR itself may not be satisfied at the daily time ...

New findings about the complementary relationship- based evaporation estimation methods

r a 200 .008 ress: Sch unl.edu Summary A novel approach has been found to estimate the equilibrium surface temperature (Te) of wet environment evaporation (Ew) on a daily basis. Employing this temperature in the Priestley–Taylor equation as well as in the calculation of the slope of the saturation vapor pressure curve with pan measurements improved the accuracy of longterm mean evaporation (E) ...

Global Land Surface Evaporation from Satellite-based Observations

Estimating the magnitude of the different fluxes in the hydrological cycle is essential if we are to predict the impacts of climate change. However, climate change is acting on a dynamic three dimensional globe where change in one region may produce impacts in another. This creates a need to expand the current climate change studies to encompass the entire globe. Evaporation is a key component ...
