Improvements to a MODIS global terrestrial evapotranspiration algorithm
TLDR
In this article, an improved version of the global evapotranspiration (ET) algorithm based on MODIS and global meteorology data has been proposed, which simplifies the calculation of vegetation cover fraction, calculating ET as the sum of daytime and nighttime components, adding soil heat flux calculation, improving estimates of stomatal conductance, aerodynamic resistance and boundary layer resistance, separating dry canopy surface from the wet and dividing soil surface into saturated wet surface and moist surface.About:

Evaluating a new algorithm for satellite-based evapotranspiration for North American ecosystems: Model development and validation
TL;DR: In this paper, a different operational approach was introduced to estimate 8-day average daily evapotranspiration (ET) using both routinely available data and the Penman-Monteith (P-M) equation for canopy transpiration and evaporation of intercepted water.

Impacts of forest loss on local climate across the conterminous United States: Evidence from satellite time-series observations
b4migpd985,b4migpd985 +1 more
TL;DR: In this paper , the authors reported new satellite analyses on local climate impacts of forest loss at 30 m resolution, which combined multiple long-term satellite products (e.g., albedo and evapotranspiration [ET]) at 700 sites across major climate zones in the conterminous United States, using time-series trend and changepoint detection methods.
