What we did

The Blue Mountains west of Sydney are not blue. But the air around them is often seen as a blue haze, especially on hot summer days.

This bluish haze is caused by a chemical reaction in the atmosphere, driven by a compound called isoprene which is emitted by eucalypts.

Our story, entitled Beating the eucalypt blues – new ways to model air quality, tells how scientists are accounting for isoprene emissions in the area around Sydney in an effort to control air pollution.

We read the journal article, interviewed Dr Kathryn Emmerson, wrote the story, sourced images, copyedited the story and sought approvals.

The story was published in CSIRO’s ECOS blog in April 2016.
