Satellite remote sensing of ash

Satellite remote sensing of ash involves using satellites equipped with specialized sensors to detect and monitor volcanic ash in the atmosphere. These sensors analyze the Earth's surface and atmosphere to identify ash clouds based on their unique spectral signatures, such as their color and density. This technology provides real-time data on ash cloud location, extent, and movement, which is essential for aviation safety and disaster management. By observing ash remotely from space, scientists can quickly assess volcanic activity, track ash dispersal over large areas, and inform decision-making without the need for direct ground measurements.
