the hargreaves-samani (hs) equation, which estimates reference evapotranspiration (et0) using only temperature as input, should be most suitable for et0 prediction based on weather forecasting data. in the current study, the hs equation is calibrated with daily et0 by the penman-monteith equation, and is evaluated to check the possibility of predicting daily et0 based on weather forecast data. ...

—This study was conducted to determine the effect of stocking rate on yield of channel catfish Ictalurus punctatus and water quality in a mixed suspended-growth (biofloc) production system with zero water exchange. Channel catfish (National Warmwater Aquaculture Center 103 strain; average fish weight 1⁄4 13 g) were stocked into nine 35-m tanks (28 m/tank) at a rate of 2.9, 5.7, or 8.5 fish/m fo...

In this study, the effects of climate change on irrigation water requirement hazelnut trees were investigated in Central Italy. The meteorological variables considered precipitation, temperature, chilling units, and Standardized Precipitation Index (SPI) hydrological reference evapotranspiration (ET0) based soil balance. Climate data collected from eight stations for period 1974–2021, ET0 was e...

Resumo A radiação solar é uma variável climatológica amplamente utilizada em estudos climáticos e pode ser mensurada por meio de estações meteorológicas. Devido ao alto custo difícil manutenção dos equipamentos mensuração, possível estimá-la a partir modelos matemáticos. Assim, o presente estudo objetivou calibrar validar os parâmetros da equação ångström-Prescott Hargreaves & Samani para r...
