The environmental drivers of annual variation in forest greenness are variable in the northern Intermountain West, USA

Ecosphere, Volume 11, Issue 8, August 2020., 2020
Abstract Peak snowpack in the western USA has decreased 21% since the mid‐20th century, and these trends are forecasted to continue over the next century. In water‐limited systems, forest productivity during the growing season is assumed to be linked with snowpack during the previous winter, but this linkage has proven not to be universal in studies ...

Erratum to: Evaluation and calibration of Blaney–Criddle equation for estimating reference evapotranspiration in semiarid and arid regions [PDF]

Environmental Earth Sciences, 2015
Penman–Monteith (FAO-56 PM) equation is suggested as the standard method for estimating evapotranspiration by the International Irrigation and Drainage Committee and FAO. On the other hand, the Blaney–Criddle (BC) temperature-based equation is an alternative and simple method compared with the FAO-56 PM equation.

Historical Rainfall and Evapotranspiration Changes over Mpologoma Catchment in Uganda

Advances in Meteorology, Volume 2020, Issue 1, 2020., 2020
Changes in the long‐term (1948–2016) rainfall and evapotranspiration over Mpologoma catchment were analysed using gridded (0.25° × 0.25°) Princeton Global Forcing data. Trend and variability were assessed using a nonparametric approach based on the cumulative sum of the difference between exceedance and nonexceedance counts of data.

Estimación de la evapotranspiración a partir de datos satelitales para la región de Alto Beni, Norte de La Paz

Revista de Investigación e Innovación Agropecuaria y de Recursos Naturales, 2021
La evapotranspiración (ET), resulta de un proceso simultáneo de evaporación y la transpiración. En una superficie de referencia, que ocurre sin restricciones de agua, se denomina como evapotranspiración del cultivo de referencia (ETo).

Forecasting daily reference evapotranspiration using the Blaney–Criddle model and temperature forecasts

Archives of Agronomy and Soil Science, 2015
ABSTRACTAccurate daily reference evapotranspiration (ETo) forecast is essential for real-time irrigation scheduling. An attempt was made to forecast ETo using the Blaney–Criddle (BC) model and temperature forecasts in this study. Daily meteorological data for the period 2000–2014 at five stations in East China were collected to calibrate and validate ...
