Launching the balloon at Australia's most remote weather stationCaddie Brain and Brendan Phelan, Monday June 16, 2014 - 09:36 EST
Every morning, on the edge of the Great Sandy Desert in Western Australia, two men carry out a very important ritual.
All over the globe, at the same moment every day, weather observers release balloons high into the sky, gathering critical meteorological information.
As the only weather radar for 2.5 million square kilometres of outback Australia, that responsibility falls to Giles Weather Station.
Built in the 1950s to support weapons testing from Maralinga and Woomera in the 1950s and '60s, Giles is the place to be if you like solitude, enormous skies, and don't mind a fly or two million.
