Bushfire smoke visible in Antarctica
Together with collaborators at the US Naval Research Laboratory and other LIDAR sites, the Antarctic Division is gathering data on the smoke layer to understand its dispersal and climate effects. The smoke particles act as nucleation sites, promoting the growth of sulphuric acid droplets. These droplets are likely to have a small effect on the climate at high altitudes, either by warming or cooling the atmosphere (which depends on the size of the droplets), and by producing chemical reactions that will ultimately result in loss of stratospheric ozone
This image was produced from LIDAR measurements collected in April and shows thin layers in the lower stratosphere that were illuminated by the LIDAR's green laser beam.
