Investigating Meteorological Intervention for Improving Air Quality in Airshed 1 Towns

The report titled "Investigating Meteorological Intervention for Improving Air Quality in Airshed 1 Towns" was presented at the Otago Regional Council. The report evaluated the potential for reducing air pollution through modifying the atmosphere above small towns (classed Airshed 1) that experience high levels of night time pollution. An advection-diffusion model was created that allowed the effect of various interventions on increasing the dispersal of smoke from home heating to be clearly assessed. These interventions including using frost-fighting fans to mix the lower atmosphere, enhancing a naturally occurring low-level (50-100 m above ground level) wind in the mid evening as well as drawing air out the Alexandra basin. It was found that none of the interventions would be able to significantly reduce levels of air pollution to within the national standards within reasonable energy limits. The model may be useful for identifying the most effective strategies for improving air quality through reducing emissions.

Alexandra Community Climate Change Discussion Forum

On Saturday 7th November 2015, the Alexandra Community Climate Change Forum was held at the Alexandra Community Centre.  The purpose of the forum was to solicit ideas from the community as to how Central Otago might respond to both the threats and opportunities posed by climate change.  The Discussion Forum arose out of deliberations within the MAD4CO (Making A Difference For Central Otago) group in the lead up to the Alexandra Thyme Festival. The goal was to host a discussion evening that would more closely link current climate change research to the needs of a small community, such as Central Otago, and to raise community awareness of the latest outcomes of climate change research.
