LSI LASTEM Penman Evapotranspiration (BSZ421)

The LSI LASTEM Penman Evapotranspiration program calculates an Evapotranspiration index reference in respect to the equation of FAO Penman Monteith. An evapotranspiration implies that the vapor of water transferred to air by vegetation or ground. The process that causes the evapotranspiration are transpiration and evaporation. The parameter that influences the evaporations include humidity, air speed, radiation and temperature. An ET0 Evapotranspiration reference is the rate of evapotranspiration of the standard surface of reference that is not at all dry. Evaporation is a process where the water is transformed from a liquid to vapor and transpiration implies the transfer of the water vapor by a vegetable tissue.

The LSI LASTEM GidasPenman can calculate an ET0 index Evapotranspiration both on a monthly and daily basis. An ET0 calculation for single or more sites includes the results report, simulated or measured, meteorological quantities. The surface of the reference is represented by the 12cm high which completely underlying the ground. With ET0,you can study the evaporative demands and its characteristic.

The Penman Evapotranspiration (BSZ421) can report using XML and is compatible with Microsoft Office. The management of various measurement calculations and points also included along with the selection of Gidas data base measurement.
