Estimation of Effective Day Length at Any Light Intensity Using Solar Radiation Data
The influence of day length on living creatures differs with the photosensitivity of the creature; however, the possible sunshine duration (N(0)) might be an inadequate index of the photoperiod for creatures with low light sensitivity. To address this issue, the authors tried to estimate the effective day length, i.e., the duration of the photoperiod that exceeds a certain threshold of light in...
متن کاملSolar Radiation Estimation from Rainfall and Temperature Data in Arid and Semi-arid Climates of Iran
Precipitation and air temperature data, only, are often recorded at meteorological stations, with radiation beingmeasured at very few weather stations, especially in developing countries. Therefore there arises a need for suitablemodels to estimate solar radiation for a completion of data sets. This paper is about an evaluation of eight models foran estimation of daily solar radiation (Q) from ...
متن کاملUsing remotely sensed solar radiation data for reference evapotranspiration estimation at a daily time step
16 Solar radiation is an important climatic variable for assessing reference evapotranspiration 17 (E0), but it is seldom available in weather station records. Meteosat satellite images processed 18 with the Heliosat-2 method provide the HelioClim-1 database, which displays spatialized 19 solar radiation data at a daily time step for Europe and Africa. The aim of the present work 20 was to inve...

متن کاملEstimation of solar radiation from cloud cover data of Bangladesh
In this study, an analysis of the monthly mean values of the fraction of the sky covered by clouds (C) of all types and the duration of bright sunshine hours (S) and global solar radiation on the horizontal surface (H) was carried out to establish relationship for solar radiation estimation for Bangladesh. The relationship between C and (1 − S/S0), where S0 is the maximum possible hours of suns...
