Thursday/ fireworks make a lot of smoke

Not to be a party pooper, but it may be time to look for high-tech options* to replace the massive fireworks displays for events such as Fourth of July. Prof. Cliff Mass reports on his weather blog that Puget Sound Clean Air Agency measured a huge spike of the dangerous PM2.5 particle in the aftermath of Thursday night’s show. From levels under 20 µg/m³, the readings increased to over 100 µg/m³, which is in the ‘unhealthy’ air quality index range.
