If light is in a simulation, how does it know what is reality? Okay, obviously light isn’t self-aware. But Dr. Morrell and his team at University of Exeter in the U.K. are creating computational models that predict the characteristics of artificial light at night. These models can show everything from how street lights will affect animals, plants, and humans. It’ll show what the glare will be like on a particular road. But most importantly, it can demonstrate how to improve the lighting before spending one pound or dollar on a light fixture.
Dr. Morrell is a postdoc researcher working between the Environment and Sustainability Institute and the Astrophysics group at the University of Exeter. He received his PhD in astrophysics from Exeter in 2020, where he researched techniques for measuring the properties of stars. Since then, he has been working on combining measurement techniques with computational models to predict the characteristics of artificial light at night at and just above ground level, in locations and at scales that humans and animals experience it. He is working to develop quantitative models to better predict the ecological impacts of our rapidly evolving urban lightscapes.

Another discussion and topic 10 years ahead of its time that should have happened 50 years ago! Oil and gas reservoir simulation was at this stage in about 1982. I know because I was there. Water and air pollution 1972. Lots of catching up to do. Analytical models can be real helpful for checking results such as a Lambertan model for LED sources. Simulation was not my area but the earth sciences are very advanced in this area so might be a good source of expertise as well. The major universities such as Stanford need to include light pollution and artificial light environmental science in their programs. Some of that climate change money would go along way on such programs. If there's a take away all I can do is applaud Dr. Morrell's brave efforts and emphasize the multi-disciplinary nature of lighting science. That means working with modelling experts, environmental scientists, environmental toxicology people, fish and wildlife, animal lab researchers, regulatory experts/lawyers, health and safety professionals. The closest effort that comes to mind is the Manhattan Project in terms of scope and urgency.
