Air Quality Insights

This site contains investigations I’ve been inspired to carry out, outside of my work as an atmospheric scientist and air quality consultant.  They are driven by curiosity about some aspects of a project, or as a response to current issues among New Zealand’s air quality community.

They are also driven my interest in data science and analytics, so these posts will not be just about the air we breathe.

This site is in its early stages – expect a mixture of technical work and storytelling.
