How does Infrared spectroscopy help monitoring air pollution?

Infrared spectroscopy is a valuable tool for monitoring air pollution as it detects specific gas molecules based on their unique absorption characteristics at infrared wavelengths. By analyzing the absorption spectra, researchers can identify and quantify pollutants such as carbon dioxide, methane, and volatile organic compounds in the atmosphere. This technique allows for real-time monitoring of air quality, helping to identify pollution sources and assess the effectiveness of regulatory measures. Additionally, it can be used in remote sensing applications to track pollution over large areas.
