Air Quality Monitoring from Space
http://www.atmospolres.com/special.html
Welcome to the world of atmospheric aerosols, clouds and climate science. Atmospheric aerosols (or PM) are complex mixture of solid and liquid particles that vary in size and composition, and remain suspended in the air. They affect human health and play an important role in weather and climate change processes. Due to high temporal and spatial variability, their characterization into climate models is highly uncertain. This blog is our science diary about latest research in this field.

Sometime I wonder are there any questions left which Google can not answer? Today I stumble upon one such question, when I was just curious to know which station is oldest running station for aerosol related observations? I know in Barrow,Alaska and South Pole, CMDL is monitoring AOD since 1977. But don't know whether these are the oldest stations. And what about black carbon, surface size distribution, PM10, scattering coefficient. I guess one can expect to get long-time series for PM10 at least.
Let us compile the list. Leave the name of station and time period in comment, you know for aerosol related obs. are being made from the station.

One more reason to study aerosols. See an interesting article on Doctor's Lounge.

I remember an incident from early days of my PhD. I was travelling in a train and a fellow passenger asked me what is that I am doing? My reply was, "I study aerosols for their climatic effects". He was thoroughly confused. What he understood from the word "aerosol" was that I am studying gases coming out of aerosol-cans affecting the ozone layer. It was not his fault. There are very few places where aerosols scientist interact with laymen about their research. I guess still the situation may be not be very different from the perspective of layman when he or she hears word "aerosol". Beside aerosol's climatic effects, laymen have many reasons to know about aerosols, if not for the sack of curiosity, for the sack of his/her health. The obvious question is where to get this information particularly in a format that a layman can understand and use it without further processing it.
Few scientists and students from University of Maryland, Baltimore county have created a blog with the support of NASA to fill this information gap. They have named it "Smog Blog". Find out more about this blog from a video that NASA has created to popularize The Smog Blog.
