Modified Advection-Aridity Model of Evapotranspiration

Modified Advection-Aridity Model of Evapotranspiration

The original and modified versions of the advection-aridity AA model of regional evapotranspiration are tested with data from the Solar and Meteorological Surface Observation Network SAMSON . The resulting long-term mean annual evapotranspiration estimates are validated against water balances of 25 watersheds that are minimally affected by human activity and contain at least one SAMSON station,...

The Complementary Relationship in Estimation of Regional Evapotranspiration: the Crae and Advection-aridity Models

Advection Influences on Evapotranspiration of Alfalfa in a Semiarid Climate

Advective enhancement of crop evapotranspiration (ET) occurs when drier, hotter air is transported into the crop by wind, and can be an important factor in the water balance of irrigated crops in a semiarid climate. Thirteen days of moderate to extremely high ET rates of irrigated alfalfa (Medicago sativa L.) were evaluated using energy balance and atmospheric coupling models to examine the mag...

Trends in Regional Evapotranspiration across the United States under the Complementary Relationship Hypothesis

The hypothesis of a complementary relationship in regional evapotranspiration allows for estimation of actual evapotranspiration on a regional scale by simple, physically based models that take into account feedbacks in land surface-atmosphere dynamics. A regional, seasonal Advection-Aridity model is used to create a monthly time-series of actual evapotranspiration for a period of 27 years at a...

Using Modified Bellani Plate Evapotranspiration Gauges to Estimate Short Canopy Reference Evapotranspiration

Modified Bellani plate atmometer has been offered as an alternative and simpler technique to combination-based equations to estimate evapotranspiration ~ET! rate from green grass surface. However, there is a lack of information on its’ accuracy in humid climates. The evaporation rate sEAd from one type of atmometer marketed under the brand name ETgage® ~or ETG! with a Number 30 green canvas cov...
