If you missed our August 29 tweet chat, here's the transcript. Read what the fire and smoke experts had to say about the FIREX-AQ field campaign and its mission to study what's in the smoke from wildfires and agricultural burning.

Mount Agung in Indonesia erupted for the first time since 1963 causing widespread evacuations on the island of Bali. But is it a climate event?

In addition to its primary mission of observing space weather, the Deep Space Climate Observatory (DSCOVR) satellite is carrying two instruments that are important to climate science: the NISTAR radiometer and the EPIC camera. 

Like a prehistoric fly trapped in amber during dinosaurs' days, airborne relics of Earth's earlier climate can end up trapped in glacial ice for eons. How do climate scientists turn those tiny relics into a story about Earth's ancient climate?

In this Earth Exploration Toolbook chapter, students select, explore, and analyze satellite imagery. They do so in the context of a case study of the origins of atmospheric carbon monoxide and aerosols, tiny solid airborne particles such as smoke from forest fires and dust from desert wind storms. They use the software tool ImageJ to animate a year of monthly images of aerosol data and then compare the animation to one created for monthly images of carbon monoxide data.

This is a series of 6 guided-inquiry activities that examine data and models that climate scientists use to attempt to answer the question of Earth's future climate.
