Nitrogen Dioxide Attributable Pediatric Asthma

Description

This site hosts an interactive R Shiny application that explores the relationship between asthma and nitrogen oxides (NOx) pollution. Users can view and interact with charts or maps to see how asthma outcomes vary with NOx levels across locations or over time, making it easier to visualize potential links between traffic‑related air pollution and respiratory health.

Questions this resource can help answer

What are the number of asthma cases per year that are a result of nitrogen dioxide (NO2) pollution?
What are the other sources of nitrogen oxides in a county?

How do I use this resource?

Methodology

The NO2 attributable asthma estimates are based on a global NO2 model incorporating satellite observations, government monitoring, and information on land use. The model may not capture all local pollution hotspots, for example non-roadway sources or atypical traffic patterns.

NOAA Air Resources Laboratory

The ARL site is a scientific research and modeling portal. Its mission is to improve the Nation’s ability to protect human and ecosystem health by studying the physical and chemical processes occurring from the soil up to about 2–3 miles in the atmosphere. It is the birthplace of the HYSPLIT model, the global standard for tracking the movement of air parcels.

Evaluating Climate and Health

The Climate and Health Program uses CDC's Evaluation Framework to monitor and evaluate the effectiveness of climate and health work. To highlight the evaluation planning process for climate and health, the program has translated the steps of the CDC Evaluation Framework into a video series. The videos showcase best practices evaluators can apply, as well as some common challenges, using real-world examples of today's most pressing climate threats, namely heat, flooding, and insect vectors.
