My name is Bobby Fontaine. I live in Lorton, Virginia, 20 miles south of Washington DC. In 1998, I drank polluted well water that caused me to become sensitive to many toxins. Lorton is next to interstate highway 395. It is congested with heavy traffic much of the time while I live just down wind of it. Being sensitive to pollution made my life very difficult until I learned how to use herbs, vitamins, nutritional supplements, diet, and exercise, to counter the effects pollutants have on my health.

It didn't take long after this happened for me to realize that weekdays were harder than weekends because there is so much more traffic on the highway during the workweek. Changes in the weather could also make it easier or harder for me on any given day. On regular workdays, the amounts of pollution that come from the highway is much higher than the amounts on Saturdays. Sunday is the most likely day for me to have the least amounts of trouble. Rain will usually clean the air making it easier for me no matter what day it is. Although if it rains briefly on a hot day when the air is already very polluted, it can make it much worse.

If it is very cold, much of the pollution has a tendency to compress near the ground. If the weather is mild, the low lying area I live in fills up with pollution and can be very hard on my health. If it gets hot, the pollution tends to rise into the sky where it is not as bad as when it is only cool or warm out. If it has been cold for an extended period of time and then warms up, it can be very dangerous, even for other people where I live. This is because the pollution buildup from the cold weather can expand to fill the neighborhood with an exceptionally thick fog of highly toxic pollutants.

Needless to say, I watched the weather and days of the week go by very closely because it dictated how I lived my daily life. It didn't take me long to realize that my health wasn't the only thing I was closely watching that was following weekly patterns. It also didn't take long to start to see correlations between what the weather would be like on more polluted days as compared to days when my health was good because the air was cleaner.

I eventually grew to understand that pollution was having an effect on weather. I had learned early on that Sunday came with the best air quality while from Monday to Friday, the air quality worsened with every day. Saturdays are still polluted because of the build up over the workweek but it lessens as the weekend progresses until early Monday morning when rush hour traffic begins again.

I began notice weather pattern coming in weekly cycles slowly over the years. The pattern is not always clear in a way that it can be shown to anyone else. But with my health as a guide, I could often come up with a reasonable explanation for why weather had passed the way it did as it related to pollution effects on the atmosphere.

All these factors combined created a personal mindset for me that forced me to watch pollution and climate follow weekly cycles. But I didn't claim that weather patterns follow weekly patterns until 2006 when I started to realize that rain was coming on the same days of the week through most of the summer. I noticed this because I have a lot of gardens. In order to water them, I have to be outside while being exposed to pollution coming from the highway. So rain is always a welcomed friend because stay indoors or focus on more important work outside.

It wasn't hard for me to see a subtle weekly rain pattern because it saved me from having to water my gardens on the same days of the week every week. During this period, it occurred to me that if I could prove that rain was falling on the same days of the week, I might be able to raise awareness about pollution from cars and trucks causing climate change. This inspired me to hope that by doing so, it might lead to lessening the amount of pollution that comes off the highway towards my home. When charting precipitation statistics, there wasn't a clear enough case to be made that there were these weekly patterns. However the seed had been planted in my mind for the idea that I may be able to inspire political momentum towards better air quality if I could prove these weekly weather patterns existed.

The fall of 2006 brought weekly weather patterns that I could not only witness easily and point out to other so they saw it too, I was also able to prove it was happening using temperature data from Ronald Reagan Airport. But having only a handful of weeks with weather following weekly patterns did not make a strong enough case to make people want to know more about it.

2007 came and went with very little easily defined weekly weather patterns. However the fall through winter months of 2008 were almost identical to 2006. So I started to learn how to use Excel to analyze data in order to prove my case that pollution effects weather as it comes out of the tailpipes of cars. This website is the result of these efforts.
