Looks like a very useful book - thanks for the link!
Today in Penang, we had clear blue skies and I fell in love with this place again - was outside for a quite a while and no eye issues. It'll be interesting to see what the average is like over the next 6 months... plus I'll be asking other people who live here about it whenever the opportunity presents itself. I so WANT this place to be IT - the place where we could have a warm, inexpensive home base... but time will tell I guess...
Here is an excellent link to a real-time world air-quality map: http://aqicn.org/map/world/
Useful to track what you see for any countries of interest over a year or so and see what shows up
