Ground-Based Detection of Volcanic Ash and Sulphur Dioxide

Thermal infrared image data displaying detection and discrimination of sulfur dioxide gas and volcanic ash from erupting volcanoes is presented. The images are obtained from an uncooled multichannel thermal imaging camera. This camera can be deployed within approximately 10 kilometers of an active volcano. Algorithms for sulfur dioxide and ash detection are detailed. The system is called Ground-based InfraRed Detector (G-bIRD), and images from the system are obtained within a few seconds, analyzed and transmitted by land line or satellite using a standard web browser, to a computer with Internet access. G-bIRD provides a method to monitor hazardous volcanic substances from the ground and could be a means of issuing complementary sulfur dioxide and volcanic ash warnings to the aviation industry.
