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... 🤯

For each pixel, the lead author Tian Li from the University of Connecticut fits a trend line (solid line left) and generates a prediction (dotted line left). When something changes, the observations stop agreeing with the prediction (middle). If the change persists for at least 14 consecutive observations, then a break point in the trend is assigned. From that point on, a new model predicts future changes. And so on and so forth (right) for the following years.
