Fig. 1From: Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observationsExample solar aureole angular distributions of the sky-radiometer at 500 nm obtained through the solar disk scan method on February 27, 2020, at Akiruno, Japan. Blue dots are measured values and red dots show the angular distribution with noise reduction using a Gaussian filterBack to article page
