Electricity usage may not be all encompassing indicator; Ex. increase in cultivated area, or more production from same land parcel (by using fertilizers, pesticides, modern techniques) will not show up as corresponding increase in electricity usage at night.
- ZeroGravitas 4y agoI believe the state of the art in these things do mix multiple different types of satellite data, night time lights is just the longest dataset we have since even crappy old satelittes could capture it. Several parallels with the various reconstructions of earth's atmosphere via proxies like tree rings and ice cores and its later recalibration with satellite measures.
