The onboard meters are usually in the nose and leading edge of the wings. The engines are turbo-prop engines that run on JP-8 jet fuel, basically kerosene.
Since they are studying pollutants in the air, it makes sense to take multiple measurements at various hours so they can see how traffic and business effects the emissions.
They are most likely being run on jet A, not JP-8
and it's "affects"
All I have in this world is my balls and my word and I don't break em for no one.
I'm going to give you the benefit of the doubt and just assume you're trolling.
