Cowtan & Way

There is no pause in surface warming.

Open Mind

You probably recall that not too long ago, Kevin Cowtan and Robert Way re-processed the data used in forming the HadCRUT4 global temperature data set. Their goal was to interpolate across unobserved areas in the best way available, by Kriging. They also used satellite data to supplement the interpolation.

As I’ve said before, since the Berkeley team released their “methods” paper I’ve believed that Kriging is the best way to approach the interpolation issue. It was one of those “Doh! — Why didn’t I think of that!” moments. Therefore, despite its relative newness, I think we should consider treating this data set as one of the “main” global temperature data sets. Only time will tell whether that comes to pass.
