What is the Beijing air pollution index and what does it measure?

This is a live feed of air quality measurements from a monitoring station in the US embassy in downtown Beijing. The station measures PM2.5 particles. This means particles that are smaller than 2.5 microns in size, like soot from diesel engines. Research shows that these are the most dangerous pollutants. The first part is the date and time. Then comes the measurement, then an index that is calculated from the measurement, then a health impact rating. Anything below 100 is good, anything above 100 is a cause for concern. The feed shows the four most recent measurements in rotation (they are generally hourly), and today's average.
