Newly discovered Young-Van der Werf Ulluq Q. effect can be seen clearly here. Compare two pictures taken with the same camera, and note the brightness difference. Digital cameras can be unpredictable with respect to light response with dark pictures. To compensate, a photometer was used, a Gossen Lunasix 3, the higher the number after the symbol “ ~ “ the greater the brightness. Of interest is the bright zone right above the horizon, this zone changes in brightness, day to day, a sure indication of trapped light, it is rather important to look at that zone, immediately above the red ban. At the top extreme left is temperature in degrees Centigrade. Following that on most pictures is the symbol “ _ / “ meaning steep surface inversion, or the symbol “_ -/ “ meaning steep upper air inversion, the steepest inversion is always displayed, if the ground based “_/ “ is used, it means the steepest inversion is immediately off the ground, if it happens to be above ground “_-/ “ will be displayed. After these symbols inversion lapse rates are given in degrees C per 100 meters…. As examples : the combination _/10.0 means steepest inversion is surface based at 10 degrees C per 100 meters; _-/ 7.8
means the steepest inversion is aloft at a rate of 7.8 degrees C per 100 meters…

From Arctic pictures alone, one can see Meteorology by way of light in action, steep inversions at the station may not necessarily mean greater brightness, greater brightness occurs wherever the steepest inversion is, either at the station or far away. These pictures show that one can do horizontal remote sensing, in fact increasing the station’s capacity to actually measure distant inversions, hence, in the future, this method will be used to augment the resolution of upper air data collection a great deal, defining quite well the very air around an observatory at distances in excess of 60 Kilometers…
