Dust Monitoring on Volcanoes
Dust monitoring of Volcanic AshesIceland's Eyjafjallajökull is a stratovolcano, which was active last year. This year, the Grimsvötn was Iceland´s active volcano. Grimm Environmental Dust Monitors are measuring particle mass and size distributions on both sites, in real time. More… |

Aviation in South America and AustraliaOn June 17th New Zealand´s aviation has been resumed and most airports in Argentina were reopened again. By using the Grimm spectrometers, especially the model 1.129 Sky-OPC, some airports could safely be reopened before the standard calculations of the VAAC would have proved. More… |

The Puyehue & Cordón Caulle in ChileOn May 7th, the volcano Puyehue in Chile caused both airports of Buenos Aires (at a distance of app. 2000 km) to be shut down. This threat for international aviation also endangered the aviation in the 3000 km distant Porto Alegre (Brazil). Now the Cordón Caulle of the Puyehue National Park erupted and had a great influencing threat even to the Australian aviation. More… |

Volcanoes are a permanent threat to our society. This newsletter presents a few hints on how Grimm products, especially the OPC 1.109 and the Sky OPC 1.129 can assist Science and aviation control to minimize the effects of these enormous natural events. |

A small timetable of notable volcanic eventsTo estimate the dangers of volcanoes for international aviation, we collected a small amount of incidents of the recent years.19.7.2011 Etna; Italy: Strong eruption. Airport Fontarossa was closed. Small impact on aviation (app. Duration: a few hours)13.6.2011 The Nabro, Eritrea: Some impact on aviation (app. Duration 1 week) |

DUST MONITORING ON VOLCANOES |
Science Nano proofScientific measurements showed, that ash concentrations in the clouds were only a few µg/m³. The flights initiated by Prof. Weber and his team were the first to measure nanoparticles in the volcanic emissions with the Grimm NanoCheck. More... |
Monitoring equipmentThe crucial aspects to aviation safety is the composition of micro particles. With the use of the 31 channel Spectrometer 1.109 or the specialized 1.129 Sky-OPC the mass and the dust size distribution can be measured in real time. More.. |
Conclusion of the monitoringAs a result of various campaigns by Prof. Weber and many of his colleagues, a lot was learned from the measurements during the Eyjafjallajökull eruption in 2010 . Unlike at the former eruption of the Eyjafjallajökull, measurements with Grimm Aerosol spectrometers and advanced methods of calculating the risk of the airborne particles contributed that aviation was hardly afflicted by the outbreak of the volcano Grimsvötn in May. |

The Sky OPC 1.129The Grimm Sky OPC, model 1.129 can help to evaluate the impact of fine particles on aviation, to prevent damage of airplanes and thus on the volcano-stressed economy. Especially its lightweight construction and durability enables this device to be operated onboard of slow flying airplanes. More... |
