NIWA`s scientists use hyperlocal air quality mapping with solar-charged sensors for precise insights. NIWA employs dense air quality sensor networks in New Zealand towns. 40 solar-powered Clarity Node-S sensors reveal block-by-block air pollution patterns. Hotspots show 3x higher PM2.5 levels than clean areas. NIWA covers 6 km downwind, capturing pollution plumes. These maps aid policymaking, forecasting, modeling, and public health by uncovering localized variability. Learn more! » View more |
