[OC] A satellite map of the atmospheric shift happening over North America's cities Visualization

What This Visualization Shows

This data visualization displays "[OC] A satellite map of the atmospheric shift happening over North America's cities" and provides a clear visual representation of the underlying data patterns and trends. The visualization focuses on This map shows the estimated lifetime of organic peroxy radicals (RO₂) across urban North America during summer 2023.

RO₂ radicals are an important part of atmospheric chemistry. How long they survive helps determine whether they quickly react with nitrogen oxides (NOₓ) and drive ozone production or remain in the atmosphere long enough to follow other chemical pathways.

Over the past few decades, NOₓ emissions have fallen across much of North America. As a result, the chemistry of many cities is changing. The study found that New York, Chicago, and Toronto have substantially longer RO₂ lifetimes than Los Angeles, giving these radicals more time to undergo reactions that can produce highly oxidized compounds and contribute to secondary organic aerosol.

The colors show estimated RO₂ bimolecular lifetime (τ\_bi), with purple indicating shorter lifetimes and green to blue indicating longer lifetimes. These patterns reflect a broader shift in urban photochemistry as NOₓ levels continue to decline.

One of the most interesting findings is that this isn't just happening in a few cities. The satellite observations suggest longer RO₂ lifetimes are becoming common across urban North America, pointing to a widespread change in how pollutants are processed in the atmosphere., which allows us to understand complex relationships and insights within the data through visual storytelling.
