Three weeks into our project at KNUST in Kumasi, we are making exciting progress in setting up a network to measure nitrogen dioxide (NO₂) pollution. Our initiative began with the goal of the KNMI of establishing a low-cost, sustainable air quality monitoring system using diffusion tubes so that the Tropomi satellite can be validated. Inspired by similar networks in Europe, we wanted to explore how this method could be adapted to the Ghanaian context, ensuring long-term local engagement and impact.
Since arriving, we have completed our first validation campaign, with the collected samples now on their way to the Netherlands for analysis. At the same time, we have been developing locally made diffusion tubes using PP pipes with PVC caps and have installed them alongside validated tubes from the Netherlands to compare their performance.
Collaboration has been a key part of this project. We have engaged with professors from chemical engineering, metrology, and climate science, many of whom are eager to integrate NO₂ measurement techniques into their teaching. This will help ensure that the work continues beyond our time here. Working closely with teaching assistants Emmanuel, Phiona, and Philip from the chemical engineering department has also been a highlight as their expertise in chemical processes complements our background in industrial design, creating a strong, interdisciplinary team.
Beyond the work at the KNUST, we have been welcomed with incredible hospitality, making our time in Kumasi both professionally and personally enriching.
