Minimizing disruption to flights during a Volcanic eruption

Volcanic ash presents a global issue for the aviation industry. In recent years volcanic events have resulted in grounded flights around the world for periods up to 30 days. Volcanic ash plumes are subject to long-range transport and are carried over large areas by strong winds, causing major disruption to the global air transport industry. Combining a decade of innovative development Raymetrics provides you with the best ground based remote sensing technology. Our systems detect ash clouds more easily and predict how they might spread, more accurately

Why choose a Volcanic Ash Detector from Raymetrics?

A whole new dimension in Aviation and Meteorology

Introducing the revolution in remote observation on the atmosphere (clouds, volcanic ash, etc), the Raymetrics 3D Ceilometer is designed to work as a visual radar, as well as to deliver records of the radiation that is backscattered in the components of the atmosphere (molecules, aerosols, clouds, etc.)

Raymetrics LIDAR Networks

Several meteorological agencies have decided to deploy LIDAR networks to aid decisionmaking in case of volcanic ash events. This includes the Met Office in the U.K, which decided to implement a national network as a direct consequence of the Eyjafjallajokull Icelandic eruption in 2010. The Met Office LIDAR network currently consists of 10 Raymetrics depolarization Raman systems scattered around the country, including one system contained in a mobile van. Raymetrics has deployed other networks and systems in Italy, Germany, Indonesia, South Korea, Singapore, China, while several other projects are under way


How do LIDARs Work?

The system emits an eye-safe laser beam into the atmosphere. Laser light is scattered by particles in the atmosphere and some is returned to a telescope.
Because the speed of light is known, the distance to atmospheric layers can be determined. From the properties of the light, certain atmospheric characteristics can also be determined
