In this study, ETo was calculated using FAO-56 Penman Monteith method. Lag-1 autocorrelation coefficient was performed to detect the presence of serially correlation in data series. Mann-Kendall (MK) or Modified Mann Kendall (MMK) and Spearman’s rho test were applied to detect the trend in annual and monthly ETo at 8 districts over 49 years (1960–2008) in the Soenath river basin, Chhattisgarh (...

Evapotranspiration is one of the most important hydrological variables in the context of water resources management. An attempt was made to understand and predict the dynamics of reference evapotranspiration from a nonlinear dynamical perspective in this study. The reference evapotranspiration data was calculated using the FAO Penman-Monteith equation with the observed daily meteorological data...

Evapotranspiration (ET) is one of the most critical components of terrestrial water balance. Estimating reliable ET across a large region is, however, difficult due to the limited number of ground monitoring stations and the heterogeneous land surface conditions. In this work, spatially distributed monthly ET estimates in the Krishna River Basin, India, were derived using Advanced Very High Res...

Evapotranspiration (ET) is a key process of the climate system because it links water, energy and carbon cycles. In this study we modified a Penman–Monteith based algorithm to estimate ET on the Tibetan Plateau at a 1-km spatial resolution for the period 2000–2010 using meteorological and satellite remote sensing data. The results showed that the average annual ET on the Tibetan Plateau was 350...

lorestan and khorramabad province has major share in chickpea production region are the one of the largest producer of chickpea (cicer arietinum l.) in iran, chickpea with more cultivation area compare to the other plants, to estimate the chickpea water requirement. the aim of this research was to determine the crop coefficients of chickpea in a research field in lorestan agriculture faculty in...

Estimating cropland latent heat flux (LE) from continental to global scales is vital to modeling crop production and managing water resources. Over the past several decades, numerous LE models were developed, such as the moderate resolution imaging spectroradiometer LE (MOD16) algorithm, revised remote sensing-based Penman-Monteith LE algorithm (RRS), the Priestley-Taylor LE algorithm of the Je...

We find over 30% of public U.S. non-financial companies have negative net-financial-obligation (NFO) during the sample period of 1965 to 2014. According to the modified DuPont analysis, NFO is defined as total debt minus excess cash and passive investments. The persistence of negative-NFO observations suggests that its occurrence is not random, raising the questions of why these firms hold such...

Abstract Reference evapotranspiration (ETo) is critical for irrigation design and water management in rainfed irrigated agriculture. The Penman-Monteith (FAO-56(PM)) equation was demonstrated to be the most reliable adaptive a wide range of humid semi-arid climates. However, it requires several environmental parameters (e.g., wind speed, solar radiation), rarely available developing countries. ...
