That technology has evolved over the years, yet some techniques are very similar to those used over 100 years ago. I have spent several decades studying combustion, including wildfire behavior and the technology used to track fires and predict where wildfires might turn. Here’s a quick tour of the key technologies used today. Spotting fires faster First, the fire must be discovered. Often wildfires are reported by people seeing smoke. That hasn’t…
