What is it about?
This study tracked air pollution, specifically PM2.5, in Grenada from 2009 to 2022 and found seasonal spikes linked to Saharan dust. These pollution levels can affect health, highlighting the need for better air quality monitoring and public health action.

Why is it important?
This study is the first to provide a long-term analysis of fine particulate air pollution (PM2.5) trends in Grenada, a region with limited monitoring infrastructure. By using satellite data alongside low-cost sensors, it reveals seasonal pollution peaks driven by Saharan dust and other natural events. These findings are especially timely given growing concerns about climate-related health risks in small island nations. The results offer critical insights for developing air quality policies and health interventions in resource-limited settings across the Caribbean.
Perspectives
As a co-author, I believe this paper is important because it fills a critical gap in air quality data for Grenada and similar small island developing states, where monitoring infrastructure is often lacking. By combining satellite-derived data with low-cost ground sensors, we’ve demonstrated a practical approach for tracking harmful air pollutants like PM2.5 over time. This is especially valuable in regions frequently impacted by Saharan dust, where exposure can have serious but underrecognized health consequences. I hope our findings will support public health efforts, guide policy decisions, and encourage further investment in air quality monitoring across the Caribbean.
