The Math behind Climate Change: Part 6
Superimposing grids on regions
As we saw yesterday, there are a lot of weather stations in Colorado and the tendency is for the number of stations to correlate to the population of an area. The red rectangle with lots of stations is the area around Denver. The sparseness of stations near the far corners of the grid corresponds to those regions being sparsely populated.
I decided to superimpose a 10 × 10 grid on the map to even out the readings somewhat and to show the reader what areas of the map are being sampled the most. The most sampled grid points are in red, the next most in blue, then the white diamond followed by the small black diamonds being least represented.
Tomorrow (finally), we will look at seasonal data and propose a system that will avoid cherry picking the method to look at trends.
