Hamilton in New Zealand benefits from its exceptional Waikato River valley position in the central North Island at 40 metres, with consistent westerly New Zealand atmospheric winds providing reliable ventilation. Vehicle traffic on surrounding roads and the agricultural services, university, and manufacturing corridor contribute local sources, while the surrounding Waikato agricultural landscape's dairy operations contribute elevated ammonia and the generally excellent New Zealand atmospheric conditions maintain Hamilton at moderate to good conditions throughout most of the year.
