The Stefan-Boltzmann constant, symbolized by the lowercase Greek letter sigma (σ), is a physical constant expressing the relationship between theheatradiation emitted by a black body and its absolute temperature. According to the Stefan-Boltzmann law,σ has avalue of 5.670374419 × 10−8wattper...
In this paper a process for estimating the Stefan-Boltzmann law constant is proposed through a study of the current-voltage curve of a 12 V bulb. The least squares treatment of the data allows the value of the constant to be determined with results that are in accordance with the data in...

Denoting εc the condensation surface emissivity and εs the nocturnal clear sky emissivity averaged on scattering angles and radiation wavelength (see below Section 3.2), one obtains, with 𝜎σ the Stefan-Boltzmann constant: 𝑅𝑖=𝜀𝑐𝜀𝑠𝜎𝑇4𝑎−𝜀𝑐𝜎𝑇4𝑐=𝜀𝑐...
where \(\sigma\) is the Stefan–Boltzmann constant and \({\varepsilon }_{s}\) is the emissivity of the snow, which we assume to be 0.9913. In addition to the in-situ observation of N-ICE 2015, we include a satellite data set of daily sea-ice surface temperature (\({T}_{{\rm...
