Fig. 5From: Rapid, accurate computation of narrow-band sky radiance in the 940 nm gas absorption region using the correlated k-distribution method for sun-photometer observationsMonthly mean atmospheric vertical profiles at the SKYNET Chiba site in 2018 obtained from NCEP reanalysis 1 data. Left and center panels show vertical profiles of pressure and temperature, respectively. Right panel is the vertical profile of water vapor normalized to PWV of 2 cmBack to article page
