Evaluating the Impact of Daily Net Radiation Models on Grass and Alfalfa-Reference Evapotranspiration Using the Penman-Monteith Equation in a Subhumid and Semiarid Climate Read More: http://ascelibrary.org/doi/abs/10.1061/(ASCE)IR.1943-4774.0000278
Irmak, S; Odhiambo, L; Mutiibwa, D (University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2011)Net radiation (Rn) is the main driving force of evapotranspiration (ET) and is a key input variable to the Penman-type combination and energy balance equations. However, Rn is not commonly measured. This paper analyzes the ... -
Evaluation of the impact of surface residue cover on single and dual crop coefficient for estimating soybean actual evapotranspiration
Odhiambo, LO; Irmak, S (University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2012-02)Single and dual crop coefficient methods are used in conjunction with grass reference evapotranspiration (ETo) to estimate actual crop evapotranspiration (ETc). However, the impact of soil surface residue cover on the ... -
Impact of microclimatic data measured above maize and grass canopies on Penman-Monteith reference evapotranspiration calculations.
Irmak, S; Odhiambo, L O (University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2009)Estimation of reference evapotranspiration (ETref) using measured microclimatic data and the Penman-Monteith (PM) method provides a powerful means of quantifying actual plant evapotranspiration (ETa) needed for use in ... -
Performance Of Extended Shuttleworth-wallace Model For Estimating And Partitioning Of Evapotranspiration In A Partial Residue-covered Subsurface Drip-irrigated Soybean Field
Odhiambo, LO; Irmak, S (University of NairobiCollege of Biological and Physical Sciences,University of Nairobi, 2011)Estimation of actual evapotranspiration (ET), especially its partitioning into plant transpiration (T) and soil evaporation (E), in agricultural fields is important for effective soil water management and conservation and ...
