A rapid and nonintrusive method to analyze traffic pollution based on the open-path Fourier transform infrared (FTIR) technique has passed a road test in two Spanish towns. The technique, which can be applied to the remote sensing of many gases, has been shown to be advantageous for monitoring many environmental problems related to atmospheric pollution, according to the researchers from the department of physics at the Universidad Carlos III of Madrid (UC3M) and the Universidad Europea de Madrid. Shown is one of the components in an infrared remote sensing setup to analyze air...Read full article

    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
