Carbon Tracker: What's the CO2 in Your Neighborhood?
NOAA has set up a carbon dioxide tracker on the web. The 'CarbonTracker' project allows anyone with an internet connection to observe the carbon dioxide flux in Earth's atmosphere. With 60 stations world-wide and 20 in the USA the resolution is not high, but it is a start. It is also not 'live' carbon dioxide tracking, as it takes about 6 months to analyze and ensure quality of the data. All of the data is free to the public, and the source code for the program is also available. This would be a cool widget to plug into Google Earth somehow- allowing people to layer and map the CO2 in their area with ease.
