Air Quality and Urban Design
NIWA urban air quality research programme
The programme aims to answer two key questions
1. How does a pollutant emitted in one place become a concentration measured somewhere else?
2. Why and how is my exposure to pollutants different from yours?

Air Quality and Urban Design
high resolution spatial and temporal measurements of pollutants
Steep concentration gradients close to roads
Mangere Bridge median UFP levels for all early morning data combined
Clear signal of elevated NO2 at roadside compared to ~150m away

Research application: Roadside assessment and land-use rules

high resolution spatial and temporal measurements of pollutants. In Auckland CBD, pollutant concentrations vary considerably over short distances

And now?
TOTUS is currently developed within the Resilient Urban Futures programme (RUF) with a focus on general usability and relevance
