As many fires are still burning in Australia, a regular GLOBE Observer (Glenn Evans in Coogee, New South Wales, about 10 km/6 miles southeast of Sydney), has been taking consistent clouds observations from the same location over the last few weeks, sometimes multiple observations on the same day. In this short video, you can see a compilation of their ground observations in December 2019, facing west and south alongside satellite imagery from the same day taken by the MODIS instrument on the Aqua satellite. Notice the sky coloration when heavy smoke plumes are visible in the satellite image, as well as the days when there is both haze and other types of clouds in the sky. Video: NASA GLOBE Observer
