Smoky Australian Skies

As satellites track Australian wildfire smoke from above, GLOBE Observer citizen scientists have been keeping tabs on hazy skies from the ground.

The photograph above shows smoke blanketing Horseshoe Lagoon in New South Wales on January 6, 2020, a day when clouds limited what sensors on Terra, Aqua, and Suomi NPP could observe as they passed over.

The video below, based on photographs taken by GLOBE citizen scientist Glenn Evans, juxtaposes satellite images and photographs taken of the sky at roughly the same place and time. The contrasting perspectives underscore how easy it can be to miss the forest for the trees — or, rather, the smoke plume for the clouds — if you aren’t careful. Kristen Weaver, the deputy coordinator for GLOBE Observer, compiled the photos and matched them with the corresponding MODIS satellite images.


Victoria and New South Wales are in the midst of one of the most severe fire seasons either state has seen in decades. After months of unusually hot, dry weather, hundreds of fires have charred an area larger than West Virginia, destroying thousands of homes and resulting in dozens of deaths.

GLOBE Observer is a citizen science project that is part of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. Through a free app for their mobile device, anyone in participating countries can make environmental observations of clouds, trees, land cover, and mosquito habitats that complement NASA satellite observations.
