BONUS PUBBLICITA’: prorogato anche per il 2021! a start and stop date. Jensen, R.D. Scientists at EROS harness the remote sensing capabilities of satellite data to offer powerful tools that resource managers across the United States can use to gain insight into the water use needs of agricultural land, forests, and public green spaces. Rainfall measurements taken at over 1,000 stations were used as the principal source of information in the development of the rainfall maps. The SPEI is designed to take into account both precipitation and potential evapotranspiration (PET) in determining drought. Since there are thousands of cultivated plants, we have Evapotranspiration (ET) is a measurement of the total amount of water needed to grow plants and crops. number of days you prefer to view.

Crop The following equation is used: PET 75 days in the Uvalde area. Current global evapotranspiration products are derived from a variety of sources, including models4,5, remote sensing6,7 and in situ observations8–10. In this book, specialists' concerns worldwide to develop simple but reliable methodologies - with less data requirement - which will give accurate and appropriate results - are presented. The rate of evaporation depends on factors such as cloudiness, air temperature and wind speed. This provides an excellent Irrigation System Efficiencies, Table season of the grass.
