Why do we need to measure ozone?

Ozone is an atmospheric trace gas found throughout the atmosphere. Most people are familiar with stratospheric ozone. This is dominated by the famous "ozone layer," approximately 6 through 30 miles...

Hi Oscar. Motion is possible still in all three directions up to the 'lid' that is the inversion. You are right about the mountains as any time there is cool air sitting on warm air, there is in effective lid on the airmass. This happens in SLC and also Denver and of course, most famously in LA and going back further, caused the Donora, Pennsylvania disaster. There is lots of things online about this stuff these days and if you want a free textbook on all things atmospheric I would recommend Daniel Jacobs book that you can download free at this URL: http://acmg.seas.harvard.edu/people/faculty/djj/book/

Hi Oscar. Thanks for the interest and of course, the pledge! We are happy to have you as a formal backer of the project. Ozone can "settle" as you put it but it is more like being trapped in a bottle by things like the heat island we talked about in the lab note. The hot air cannot go anywhere and hence, ozone and ozone precursors build up and up leading to very poor air quality. This is similar to what happens for example, in Salt Lake City when temperature inversions trap air-masses close to the city, where, they become heavily polluted. A ground based sensor will give readings on the ground but, ozone aloft can be significantly different depending on the chemistry and dynamics of the elevated air. Hope that answers your question! Best wishes, Gavin.

Hi Richard. Thanks for your interest in our project. As Chris said there are new an novel technologies coming to market all the time. Small sensors like the type we are hoping to use are possible for the applications you spoke of, I am sure they would be able to show a response given the likely CH4 concentrations in the environments you are encountering. The most obvious way to get good data would be using some kind of dynamic sampler (e.g. pump and bag) to collect air on site and then, analyze by Gas Chromatography. There are several columns that are specifically set up to do methane. In fact Chris and I use one here at EMU. Of course, the drawback is once again $$. Good luck!

Hi Linda and thank you for your support, we appreciate you making a pledge to support this research. I am not familiar with HESTIA but it does sound like a worthwhile endeavor. There are many cities that are tracking pollution in new and novel ways, I will investigate further. Thanks for the tip!
