I found this website run by the State of New York that monitors Air pollution. Its a good site but the "weather centers" are too far and few between to really get a feel for air quality city wide by neighborhood.

So, for example, in Manhattan what are the better neighborhoods for clean air, and some of the ones that will give trouble for those with respiratory issues?
Same for some of the outer boros.. What are the good and bad neighborhoods?
(From Personal Experience, Washington Heights by the GW Bridge was unbearable, dark black soot everyday in the house, could barely breathe, same with Times Square, and much of Midtown.)
In general I found the outer boros to be a bit better, but Hunts Point was not so good by the Bruckner Expressway. Although the areas around LGA Airport seemed much cleaner despite GRand Central Parkway, (maybe terrain).
So is Inwood better than Washington Heights (because of the terrain, shielded by that huge hill with trees) Is the Lower East Side awful despite being waterfront because of Brooklyn? I would guess the Rockaways have excellent air b/c of the ocean, and Staten Island Because of the trees.
So.... What are your air quality experiences with different boros, and different neighborhoods?
