Validation of the net radiation through sebal algorithm in different classes of land use and occupation in Rio de Janeiro

Bioscience Journal, 2016
The aim of this study was (a) to assess and evaluate the net radiation (Rn) by SEBAL algorithm and (b) to assess the net radiation (Rn) by the landscape's spatial temporal dynamic using ISODATA algorithm, in entire city of Rio de Janeiro.

Hargreaves Equation as an All-Season Simulator of Daily FAO-56 Penman-Monteith ETo

Agricultural Science, 2013
This work showed the Hargreaves equation (HG) can be modified into a highly efficient computational replacement for the FAO-56 Penman-Monteith equation and its auxiliary functions for the computation of daily reference evapotranspiration (ETo) estimation when only available data are daily temperature data. By modifying all the constants (i.e., '0.0023'

Evaluation of Valiantzas’ Simplified Forms of the FAO-56 Penman-Monteith Reference Evapotranspiration Model in a Humid Climate

Journal of Irrigation and Drainage Engineering, 2017
AbstractThe unavailability of some meteorological variables, especially solar radiation and wind speed, is the main constraint for reference evapotranspiration (ETo) estimation using the standard U...

Evaluasi Metode Penman-Monteith dalam Menduga Laju Evapotranspirasi Standar (ET0) di Dataran Rendah Propinsi Lampung, Indonesia [PDF]

, 2012
Evapotranspiration is an important factor in estimating crops water use and then irigation schedule. Direct measurement of evapotranspiration is difficult since it is influenced by many factors.

The Global Crop Water Model (GCWM) : documentation and first results for irrigated crops [PDF]

, 2008
A new global crop water model was developed to compute blue (irrigation) water requirements and crop evapotranspiration from green (precipitation) water at a spatial resolution of 5 arc minutes by 5 arc minutes for 26 different crop classes. The model is
