![]() The “main pollutant” indicates which of the six criteria pollutants is present at the riskiest levels (usually PM2.5 or ozone). ![]() Monitor Portland air pollution data at the top of this page to stay aware of pollution spikes and health advisories. Meanwhile, ozone, a secondary pollutant, only becomes problematic in the summer, when abundant sunshine and heat create ideal conditions for its formation. Fine particle pollution tends to rise in the winter months with increased household wood burning and pollution-trapping temperature inversions. In Portland, each season brings unique pollution challenges. This is a slip from Portland’s “A” rating in the 2014 to 2016 monitoring period, which experienced less than 1 unhealthy day a year. 1 Due to the frequency of these events, the American Lung Association (ALA) graded Portland a “C” for 24-hour PM2.5 and 24-hour ozone in their 2019 State of the Air report. ![]() In the most recent 3-year monitoring period spanning 2016 to 2018, Portland averaged roughly 3 unhealthy pollution days a year. The concerning trend coincides with a growing population and number of vehicles on the road, numerous EPA regulatory rollbacks, warming global temperatures, and more frequent and severe wildfires. 45.Portland air quality has achieved a mean annual air quality index (AQI) rating of “good.” For the last two decades, Portland has achieved air pollution standards set by the Environmental Protection Agency (EPA) for all six criteria pollutants measured in real-time: PM2.5, PM10, ozone, carbon monoxide (CO), nitrogen dioxide (NO 2), and sulphur dioxide (SO 2).ĭespite this success, Portland’s air pollution levels have been climbing since 2016.

Particle systems can be confusing and difficult to understand, but once you complete this tutorial, you'll be well on your way to mastery of the Secrets of Particle Playground.Table of Contents:1. From there, Richard walks you step-by-step through creating the Matrix Code Effect, as featured in the popular Matrix films, and how to customize it for your own title sequences. You'll also learn how to use image sequences to create run cycles and animated particles. Richard dives in at the deep end to show you how to create unique particle effects like snow and fountains, before taking you into Particle Playground's incredible particle text effects.You'll learn cool techniques you can use in your productions, like the ever-popular revealing of a logo from a string of randomized letters, bouncing animated text off a wall with real physics properties, and blowing up selected letters in a line of moving text. ![]() Our Particle Playground expert Richard Lainhart fills you in on the basics of how particle systems work, and how they differ from After Effects' standard keyframing techniques. Yet Particle Playground is a wonderful environment for all kinds of effects (particularly text effects) that are difficult or impossible to achieve with other tools. Learn the little-known secrets of After Effects' Particle Playground plugin with special effects expert & Star Trainer Richard Lainhart.The Adobe After Effects Particle Playground plugin is a powerful environment for particle systems & other eye-catching special effects, but few After Effects users even know it's there! And what's more, many of those who do find its interface mysterious and intimidating. ![]()
