[Air Density]

I have managed to find a tool to work out Air Density, not a forecast tool but with a little work can be used to make a forecast from the existing models.

For those interested it can be found here: http://barani.biz/apps/air-density/

[Air Density]

Are there any "Air Density" forecasts available for the UK? I am extremely interested in finding any such.

3 months ago I was diagnosed with severe COPD, a respiratory disease that leaves you with shortness of breath (SOB). I read on the British Lung Foundation site that a change in the weather can trigger flare-ups which piqued my interest somewhat. Over that time I noticed my SOB was better and other days worse, my first instinct was to make observations between my WX readings and pollution readings  with my SOB symptoms to see if there was any sort of pattern showing. Although I need to run the comparisons for a lot longer yet, I have a result that is worth investigating , it is "Air Density" that stands out as the major player. A (specific gravity) reading higher than 0.0745 makes a good day, a reading of less than 0.0740 makes for a bad day, in my personal experience. Knowing in advance of good days would be brill, I have things left to do in life yet.
