Gwad'Air's study of air pollution in the middle of the ocean with a Kunak AIR Pro air quality station.

Atmospheric pollution is an important issue that concerns all of us, even in the middle of the ocean.

That is why Gwad’Air, the regional air quality observatory in Guadeloupe and part of the national federation ATMO France, installed a Kunak AIR Pro air quality sensor, nicknamed Hom’Air, on the boat of French yachtsman Roland Jourdain.

The boat, called We Explore, is a 50-foot catamaran dedicated to professional activities and is a true ambassador for sustainable development, as it is made of flax fibre. During the crossing between Pointe-à-Pitre and Concarneau (Brittany) (Route du Rhum), the Hom’Air will measure atmospheric pollution.



The Hom’Air sensor is an eco-responsible device that measures air quality in real-time and sends the data to a remote server. Thanks to its solar panel, it can operate with total autonomy. It is configured to measure the different atmospheric pollutants every 10 minutes: fine particles, nitrogen oxides, carbon monoxide, tropospheric ozone, hydrogen sulphide and ammonia.



This innovative experience between Gwad’Air and We Explore will improve the understanding of air quality at sea. Nathalie Laul, director of the Regional Air Quality Observatory, points out that pollution moves in the ocean, as well as in the air, and that in Guadeloupe they are very aware of this because of the particulate matter that travels from Africa.

It is an unprecedented project as it is the first time that air pollution has been studied in the middle of the ocean thanks to the installation of Hom’Air on the We Explore. The data collected by the sensor will improve knowledge about air quality in the sea and help find solutions to protect the environment.

Furthermore, Hom’Air is an eco-friendly and sustainable sensor that is charged by solar energy, making it even more attractive to those looking to reduce their impact on the environment.

Innovation and technology come together to tackle one of the most important issues of our time: air pollution. With Hom’Air, we can take another step towards a cleaner and more sustainable future.
