Lesson Overview: In this activity, students learn that smoke from wildland fires can either disperse readily or stick around, reducing visibility on the earth’s surface and making it difficult to breathe. Then they apply health guidelines regarding smoke to a very important…

Airborne measurements of 13 trace gases from seven forest fires in North America are used to determine their average emission factors. The emission factors are then used to estimate the contributions of biomass ubrning to the worldwide fluxes of these gases. The estimate for NH3…
