This post looks at the North West corner of the HADCRUT3 Gridded data for the last 15 years. It is a continuation of this post.

But Northwest I mean Latitude above 0, Longitude < 0. Roughly North America.

In the first map, I am showing the grid cells that have 170 data points out of the last 180 months. I believe that is close to what CRU does for the HADCRUT3 data summarized by month. The 2nd map has all the grid cells with 2 or more data points.

The * represents the magnitude of the data roughly. If there is a + it is too large to show (like the giant red star). Red = warming. Blue = cooling.
