This is a 5-year old interface to view CRUTEM station data. Enable Flash to view it. Zoom in by dragging a rectangle. Click on a station to view the long term trend. Click anywhere to zoom out. The graphs show average temperatures in red on left hand scale and temperature anomalies in green on the right hand scale for every station up to 2012.
It shows just how small warming effects are on a local level compared to natural variation. I may get round to updating it to 2017.
