Title Some Recent Work on the Light of the Night Sky1 Type Journal Article
Year 1928 Publication Nature Abbreviated Journal Nature
Volume 122 Issue 3070 Pages 315-317
Keywords Airglow; Natural Sky Brightness
Abstract T is now well known that the light of the night sky has little in common with the day sky. When the sun is 18° below the horizon, and the moon also below the horizon, night conditions may be considered to be established. A clear sky is of course necessary for the study of the luminosity. Unlike the day sky, it is found to exhibit very little polarisation. The intensity is considerably below the threshold of colour vision, and subjective impressions about its colour, which is sometimes described by imaginative writers as blue, have no basis in reality.

Title The Colour of the Light from the Night Sky Type Journal Article
Year 1921 Publication Proceedings of the Royal Society of London. Series A Abbreviated Journal
Volume 99 Issue 696 Pages 10-18
Keywords Natural Sky Brightness; Airglow; Skyglow
Abstract The general light of the sky at night is very faint, and beyond the observations of Campbell and Slipher, who could always detect the aurora spectrum line in temperate latitudes, nothing appears to be known of its spectroscopic or chromatic character. ...

My own observations, now to be recorded, indicate that at the time and place where I was working little, if any, of the light could be attributed to the green aurora line.

Title Colour of the Night Sky Type Journal Article
Year 1920 Publication Nature Abbreviated Journal
Volume 106 Issue 2653 Pages 8
Keywords Natural sky brightness; airglow
Abstract So far as I have been able to learn, little or nothing is known about the colour of the night sky. The light is too faint for ordinary visual discrimination of colour, which disappears with diminishing intensity of illumintion much Before the light it self ceases to be perceptible.

Title The Colour of the Night Sky Type Journal Article
Year 2020 Publication Journal of Imaging Abbreviated Journal J. Imaging
Volume 6 Issue 9 Pages 90
Keywords Skyglow; Natural light; Instrumentation
Abstract The measurement of night sky quality has become an important task in night sky conservation. Modern measurement techniques involve mainly a calibrated digital camera or a spectroradiometer. However, panchromatic devices are still prevalent to this day, even in the absence of determining the spectral information of the night sky. In the case of multispectral measurements, colour information is currently presented in multiple ways. One of the most frequently used metrics is correlated colour temperature (CCT), which is not without its limitation for the purpose of describing especially the colour of natural night sky. Moreover, visually displaying the colour of the night sky in a quantitatively meaningful way has not attracted sufficient attention in the community of astronomy and light pollution research—most photographs of the night sky are post-processed in a way for aesthetic attractiveness rather than accurate representation of the night sky. The spectrum of the natural night sky varies in a wide range depending on solar activity and atmospheric properties. The most noticeable variation in the visible range is the variation of the atomic emission lines, primarily the green oxygen and orange sodium emission. Based on the accepted models of night sky emission, we created a random spectral database which represents the possible range of night sky radiance distribution. We used this spectral database as a learning set, to create a colour transformation between different colour spaces. The spectral sensitivity of some digital cameras is also used to determine an optimal transformation matrix from camera defined coordinates to real colours. The theoretical predictions were extended with actual spectral measurements in order to test the models and check the local constituents of night sky radiance. Here, we present an extended modelling of night sky colour and recommendations of its consistent measurement, as well as methods of visualising the colour of night sky in a consistent way, namely using the false colour enhancement.

Title Study on the Influence of Port Coastal Light Pollution on Visual Navigation Type Journal Article
Year 2020 Publication Journal of Coastal Research Abbreviated Journal Journal of Coastal Research
Volume 115 Issue sp1 Pages 250
Keywords Safety; Vision
Abstract Navigation aids are navigation aids for the safety of ships. They are divided into three categories: visual navigation aids, audio navigation aids and radio navigation aids. It provides reliable navigation safety guarantee for water transportation, fishery, marine development and national defense construction, and provides reliable navigation safety guarantee for the establishment of safe economic passage at sea and inside sea, which is an important part of the maritime Silk Road. Visual navigation aids are the most basic navigation aids, sound navigation aids only play a warning role, radio navigation aids have developed into a modern all-weather navigation aids system, especially the popularization of satellite navigation technology, put forward higher requirements for visual navigation aids.
