WHO releases stricter air quality guidelines to protect human health. The new standard for fine particles (PM2.5) is halved, stressing that exposure to PM2.5 is a major health risk.
PM2.5 levels peaked late at night and early mornings at our sensor test site and we struggled to find out why. Turns out the answer had fur and four legs.
We are running our airminer 2.0 sensors to calculate local pollen levels. As expected, pollen levels vary with temperature and precipitation, but we also see significant variations through the day.
We've attempted to compare the different PM2.5 breakpoints in selected air quality indices. It turns out a green level does not mean the same around the world.
