GISS September 0.77°C, up by 0.08°C

This my first report in the new style, where I record details of both mesh-weighted and traditional grid-weighted TempLS, along with the latest GISS. It is part-mechanical, but I annotate. TempLS numbers on the latest data page are constantly updated, but the monthly reports here won't change.

So the headline is, a very warm month. I think in GISS at least, 2014 may well be a record year. TempLS mesh showed a similar rise; TempLS grid dropped slightly. I expect the mesh version to more closely follow GISS, and the grid version to continue tracking NOAA. My next post will probably be an updated explanation of TempLS.

I've given both TempLS maps below. You can see again that TempLS mesh is closer to GISS than grid.
