You might have seen previous studies (including several from me) showing that lighting on the country and continental scale is increasing. Globally, the rate of increase is about 2% per year.
Those studies looked at (very) large areas, and used monthly or annual composite images. The new study analyzes change at the spatial scale of individual pixels (~0.5 square km) and at the temporal scale of individual nights.

That's like... A whole lot of work. A mindbogglingly large amount of work. There were 1.16 million daily (NASA Black Marble) *images*. Now think about how many pixels make up each image... 🤯
