  • Irradiance - an overview | ScienceDirect Topics
    2 5 Irradiance effects The irradiance experienced by phytoplankton in the Southern Ocean is controlled primarily by three factors: (1) the degree of ice cover (including both thickness and overlying snow cover), (2) the depth of vertical mixing, and (3) the time of year (and hence photoperiod and solar angle); factors that are discussed in detail by Smith and Sakshaug (1990)
  • Irradiance - an overview | ScienceDirect Topics
    The extraterrestrial solar irradiance is the solar radiation received at the top of Earth’s atmosphere The extraterrestrial solar irradiance varies slightly due to variations in energy emitted by the Sun and the variable distance of the Earth from the Sun in the course of the year
  • Solar uv irradiance, its variation, and its relevance to the earth
    An irradiance time series having a very uncertain absolute initial calibration may still be quite useful if its relative errors are low Accordingly, long-term measurement time series from a single instrument are preferred over time series having a similar number of non-redundant measurements by different instruments over an equivalent time frame
  • IrradianceNet: Spatiotemporal deep learning model for satellite-derived . . .
    Solar irradiance forecasting can be traced all the way back to the late 19th century when numerical weather prediction models (NWP) were first developed (Yang et al , 2018) Since then, numerous methods have been developed to improve forecast horizons spanning from very short-term forecasts to multiple days ahead (Lorenz et al , 2009)
  • The environmental factors affecting solar photovoltaic output
    In addition, solar irradiance is not constant, and varies over the timescale of decades Gradual shifts in atmospheric conditions alter global horizontal irradiance (GHI), referred to as ‘dimming’ and ‘brightening’ phases [247] Solar irradiance declined from the 1960s to the 1980s, followed by a partial rebound post-1980s [248, 249]
  • Direct normal irradiance related definitions and applications: The . . .
    Historically, the interest in accurate measurement of DNI started decades ago Early studies (e g , Linke, 1931, Linke and Ulmitz, 1940) identified the difficulty of separating the measurement of DNI from that of the diffuse irradiance in the immediate vicinity of the sun, hereafter referred to as circumsolar irradiance
  • Modeling daylight availability and irradiance components from direct . . .
    Modeling daylight availability and irradiance components from direct and global irradiance 281 3 2 Diffuse irradiance and illuminance on tilted "~ r surJaces modeling These models estimate the total (integrated) sky diffuse irradiance illuminance received by a surface ~~ = tilted from the horizontal (e g , a window)
  • Long-term changes in solar activity and irradiance
    The total solar irradiance (TSI) is the spectrally integrated radiative energy flux incident on the top of the Earth’s atmosphere at the mean Sun–Earth distance of 1 a u , and it describes the total radiative energy of the Sun received by Earth’s system
  • Clear sky solar irradiance models: A review of seventy models
    Clear sky models can be broadly classified into empirical and physical models [13] Empirical or parametric models are simplified parameterizations of the atmospheric attenuation processes that provide analyitical expressions to estimate clear sky irradiance using some atmospheric components as inputs
  • Calibration of solar pyranometers for accurate solar irradiance . . .
    Solar irradiance was recorded using all pyranometers, with comparisons made against a reference pyranometer The data demonstrates a reduction in measurement errors post-calibration Calibration factors for each pyranometer were calculated to improve the accuracy of future solar irradiance measurements
