Air quality, meteorology: Though neither friends, nor foes, destined they are to be juxtaposed!

Like like magnetic forces that repel each other, air quality and meteorology would seem. We can see neither, yet, we know they’re there. Which makes describing their relationship – relationship, as in how they interact – difficult for one to put one’s finger on. But, is all of this even important? I believe it is absolutely! … Read more
