Historical data from global temperature stations

This KML by Ken Mankoff shows historical temperature trends from temperature stations around the world -- data is from the Goddard Institute's aggregation. To view this file in Google Earth, click here.

This KML represents a large amount of complex data, so please be sure to read these notes before using, and be ready for questions.

The stations are shown with a pin. The legend is:

• Airplane if the station is located at an airport, otherwise pin color is the temperature trend. Range is -0.5 to 0.5 deg/decade.
• Size is number of years of data. 25 through 130 years is pin size 1 through 2. Less than 25 years of data is pin size 0.5
• Opacity is inversely related to population of nearest city. Ruralstations are 100% opaque, city stations are 50% transparent.
  
• Clicking on a pin/airplane shows a graph and other data. The graph is of annual average temperature (*) with a 1st order line fit to the data. If the station is located outside the tropics then in addition the JJA and DJF data is plotted with a fit. The summer/winter plots are shown in red/blue respecitely (hemispheric dependent)
• In the station bubble with the plot there is also a link to the raw data.
