Estimation and mapping transpiration with basal and stress crop coefficients de...
Santos, Francisco L.; Correia, Maria Manuela; Pôcas, Isabel; Valverde, Pedro C.; Coelho, Renato; Vaz, Margarida; Paço, Teresa A.The use of remote sensing for obtaining evapotranspiration (ET) from natural and agricultural surfaces is already widely used. For irrigated agriculture the two basic approaches are: (1) the solution of the energy balance equation, using remotely sensed surface temperatures and reflectances to estimate variables and components of this equation, and (2) the crop coefficient and reference evapotranspiration (ETo)...
Evapotranspiration from a Mediterranean evergreen oak savannah: The role of tre...
Paço, Teresa A.; David, Teresa S.; Henriques, Manuel O.; Pereira, João S.; Valente, Fernanda; Banza, João; Pereira, Fernando L.; Pinto, ClaraMediterranean evergreen oak woodlands of southern Portugal (montados) are savannah-type ecosystems with a widely sparse tree cover, over extensive grassland. Therefore, ecosystem water fluxes derive from two quite differentiated sources: the trees and the pasture. Partitioning of fluxes according to these different sources is necessary to quantify overall ecosystem water losses as well as to improve knowledge o...
