The Ultraviolet Linear Stokes Imaging Polarimeter (ULTRASIP) is an advanced imaging system designed to track subtle changes in atmospheric polarization, providing a new way to assess air quality and detect and monitor environmental changes, such as wildfires. This ground-based instrument captures ultraviolet light to pinpoint the position of neutral points that are key atmospheric markers that shift due to changes in aerosols like wildfire smoke, dust, or pollution. By analyzing the sky neutral polarization points, this technology allows for continuous, precise measurements that are less affected by surface reflections or cloud interference. By offering a highly detailed view of atmospheric conditions in real-time, ULTRASIP has the potential to improve environmental monitoring and provide early warnings for air quality issues. Background: Traditional atmospheric monitoring methods, such as Aerosol Robotic Network (AERONET) and satellite-based remote sensing, are limited in their ability to detect changes beyond their immediate line of sight. These systems rely on clear skies and direct observation of particulate matter, making them less effective when clouds or other obstructions interfere. Additionally, wildfire detection often depends on visible smoke plumes, which means fires may go unnoticed until they have already spread. ULTRASIP offers a new approach by using polarization analysis to track changes in the atmosphere even when smoke or aerosols are not directly visible. Unlike conventional monitoring systems that rely on direct observations of particulate matter, ULTRASIP detects broader atmospheric variations by analyzing how light is scattered in the sky. By continuously monitoring the position of neutral points, this system provides an alternative way to assess atmospheric turbidity, detect pollution events, and improve early warning capabilities for wildfires.
