Why only 196.9 million temperature measurements? That’s one per square mile. Not hardly enough! Needs to be many times more dense than that.
And one more thing: the thermometers are at what height? 6 feet? Why 6 feet? because a man is 6 feet tall? dumb reason. The atmosphere is not a flat surface. It is measured in 3 dimensions. So you need thermometers at various heights, not just at 6 feet. How high will you go? It gets colder as you go up, so obviously the “scientists” are not going to go up.
Bottom line is that this measures the temperature of the air. That’s not the temperature of the Earth.

A very interesting point.
