Modalità di verifica dell'apprendimento
The course provide a series practical activities on implementing the evapotranspiration following Penman-Monteith utilizing set of meteorological data. The activities carried out are the subject of a detailed written report to be delivered to the teacher before the exam. The oral examination focuses on the critical commentary and discussion of the written report.

Programma
Soil hydrology: theoretical aspects of water dynamics into the soil.
Practical calculation of water flows into the soil.
Agrometeorology: Structure of the atmosphere. Composition of the atmosphere, greenhouse gases and aerosol.
Solar radiation: physics of radiation, solar irradiance spectrum at top of atmosphere, absorption of radiation by atmosphere, radiation balance.
Water in the atmosphere: water vapour, evaporation process, condensation. Water cycle, relative humidity, saturation deficit.
The evapotranspiration (ET): evaporation from the soil, transpiration by the crops, aerodynamic and surface resistances. Calculation of ET by Penman-Monteith. Crop coefficients.
Modeling: Presentation of the Daisy cropping system simulation model
Description of the different components in Daisy: Water, SOM, Nitrogen, Crop, Climate, Management, using also information derived from course SOIL PLANT CLIMATE SYSTEM MODELING 1

The course will give the basis to use and exploit in an optimized way weather and climate for agricultural production, source of food and incomes for the majority of world population. The scientific basis for a good understanding of operational applications in agrometeorology will be offered.
