Sydney-siders woke to a red dawn and crimson skies this morning as the worst dust storm on record pushed pollution levels to a record high - at more than 1500 times their normal levels.
NSW Department of Climate Change and Water, told The Sydney Morning Herald .. fuagf: please open .. imagine the sunrise we were so lucky to see .. http://www.smh.com.au/multimedia/national/dust-storm-swallows-sydney/20090923-g19h.html .. initial estimates showed the dust plume stretched 600 kilometres along the NSW coast from Sydney to the Queensland border this morning, dumping up to 75,000 tonnes of dust per hour into the Tasman Sea.
"It's travelled about 1500 kilometres to get to Sydney," Dr Leys said.
Chris Eiser, manager of atmospheric science at the department, said measurements taken in Sydney today showed the highest level of particle concentration on record.
A normal day would see around 10 micrograms of particles per cubic metre of air and a bushfire might generate 500 micrograms.
