Spatio-temporal characteristics of meteorological drought based on the MCI of Penman–Monteith

open access: yesNatural Hazards, 2023
Abstract The severity of global climate change is increasing, resulting in more frequent occurrences of drought disasters. Accurate evaluation of Spatio-temporal changes in drought using drought indices is of significant practical importance. This study employed the MCI based on Penman-Monteith, in combination with Kriging spatial interpolation,

Estimating daily net radiation in the FAO Penman–Monteith method

open access: yesTheoretical and Applied Climatology, 2016
In this work, we evaluate the procedures of the Manual No. 56 of the FAO (United Nations Food and Agriculture Organization) for predicting daily net radiation using measures collected in Tandil (Argentina) between March 2007 and June 2010. In addition, a new methodology is proposed for estimating daily net radiation over the reference crop considered ...
