Once a year, technicians from NIWA’s North Island Field Team don helmets and head lamps to check a network of CO2 sensors in the world-renowned Waitomo Caves. The sensors help make sure that heavy breathing visitors aren’t wrecking the caves’ precious natural structures and microclimate.

Some of the most striking images of lockdown around the world have been the blue skies of cities ordinarily choking in smog. From New Delhi to Los Angeles, Beijing to Paris, the changes were so remarkable they were visible from space.

NIWA scientists have set up air quality sensors every 100 metres across Arrowtown in what is believed to be the world’s densest air monitoring network.

Seven weeks of lockdown has provided evidence of how pollution can vanish overnight with benefits for the environment and individuals, says NIWA air quality scientist Dr Ian Longley.
