Hi Judith. This is a reasonable comment. As you know, I am not trying to do a long term monitoring study and so there is nothing we can do about the timing. That said, Bellingham does have some of its worst air quality days in the winter when winter stagnation events settle in between storm periods. I am pretty up on the local AQ and weather conditions and so I'll be doing my best to design a useful study. Dan

Earl- We have some data from summer 2014 that we are analyzing now and should get published into a new paper by next June. The B'ham study will hopefully happen this winter and so a final report would be available about 6-8 months afterwards.
