Evapotranspiration is an important parameter to know in the management of agricultural water resources. There are several methods for estimating evapotranspiration (ETo). The FAO Penman-Monteith method considered universal standard ETo, however, climate data needed calculate ETo not always available, so it necessary evaluate performance using equations as a comparison evapotranspiration. This s...

Potential biases in tree-ring reconstructed Palmer drought severity index (PDSI) are evaluated using Thornthwaite (TH), Penman–Monteith (PM), and self-calibrating Penman–Monteith (SC) PDSI in three diverse regions of theUnited States and tree-ring chronologies from theNorthAmerican drought atlas (NADA).Minimal differences are found between the three PDSI reconstructions and all compare favorabl...
