Fig. 4

An exemplar of outputs from a single temporal acquisition of the VNIR HLS and thermal camera at two elevation angles for a morning scan on Jan 1st, 2018 at 07:45 (UTC + 10). a, b depicts RGB true colour composites at the − 20° θ and − 32.5° θ central elevation scan angles; c, d depicts the corresponding thermal imagery corrected for thermal interferences with the temperature colour bar to the right hand side; e depicts the irradiance from the start of the − 20° θ and − 32.5° θ central elevation scans; f depicts the all sky image from the start of the − 20° θ scan. Sun position at time of acquisition: 98° azimuth, 31° elevation. Part of the mounting platform is visible in the right-hand-side of the scans. Note that this and subsequent panoramic images are not orthorectified
