Saharan dust makes snow melt faster
Saharan dust makes snow melt faster

The extent to which the entire atmosphere is globally connected was shown by the last Saharan dust event on the Sonnblick. The desert sand deposits are clearly visible in the photos. A dark surface reflects less incoming solar radiation and thus heats up the surface more quickly. The change in albedo caused by the deposited Saharan dust causes the snow to melt.

Forest fires & volcanic eruptions - A review of the year 2021
Forest fires & volcanic eruptions - A review of the year 2021

In the summer months of 2021, a number of forest fires were registered in Europe. Areas in Italy, France, Greece and Turkey were hardest hit by large fires. In order to investigate the transport of carbon monoxide (CO) to the Sonnblick, the period 15.7. simulated with the WRF-Chem model including forest fire emissions from IS4FIRES (FMI) until August 31, 2021. No other emission sources and no…

Volcanic eruption on the island of Tonga

The volcanic eruption on Tonga shows the sensitivity of the earth's atmosphere and the interconnectedness around the globe. On Saturday, its explosion could be heard several thousand kilometers away, including in Australia and New Zealand. Although no acoustic signal was heard in Austria, the arrival of the pressure wave could still be measured. The pressure wave reached us with a delay of…

New head technician at the Sonnblick observatory
New head technician at the Sonnblick observatory

The Sonnblick Observatory is pleased to welcome a new colleague to its ranks. After a long, exciting tender, the decision was made in favor of Simon Feigl. Mr. Feigl originally comes from Steyr and can already look back on a great deal of international experience. After studying technical physics at Graz University of Technology, a stay at the CERN research center in Geneva followed, in parallel…

Exciting light appearance at Sonnblick Observatory
Exciting light appearance at Sonnblick Observatory

This morning (05.11.21) the technicians at the Sonnblick Observatory were able to photograph an exciting light phenomenon. This phenomenon is a light column, which is counted to the halo phenomena. Starting from the sun you can see a beam of light. This effect is usually observed more in the northern regions, near the Arctic. In the past, such phenomena were often interpreted as something…

Nanoplastics measured for the first time at the Sonnblick Observatory
Nanoplastics measured for the first time at the Sonnblick Observatory

The results of the study by Dr. Dušan Materić brought exciting results which were carried out as part of the "Transnational Access Program" of the EU project INTERACT (supported by the EU Horizon 2020 project INTERACT, grant agreement No. 730938). The aim of the NIRA (Nanoplastics In Remote Air: types, concentrations and size distribution) measurement campaign is to detect…

Eventful measurements at the Sonnblick observatory
Eventful measurements at the Sonnblick observatory

The events of September 26th, 2021 show how sensitive the measuring devices are at the Sonnblick Observatory. An increased dust mass concentration was detected in the early hours of the night and morning. After verification of the data (trajectories, negative exponent of the single scattering albedo), this event is Saharan dust. This can be seen very clearly in the graphic (dust mass…

Measurement campaign at SBO - BOKU calibrates Brewer

The Brewer spectrophotometer is a sophisticated optical instrument. It allows near-simultaneous observations of total ozone column (TOC) and sulfur dioxide (SO2) between the instrument and the sun. It can also make high-resolution spectral measurements of ultraviolet (UV) radiation in the direct solar beam or across the entire sky. More than 25 years ago, the University of Natural Resources and…

Measurement campaign at SBO - Utrecht University, IMAU: Project NIRA

In the framework of the "Transnational Access Program" of the EU project INTERACT (supported by the EU Horizon 2020 project INTERACT, grant agreement no. 730938 ) the measurement campaign NIRA is currently taking place at Sonnblick Observatory. NIRA (Nanoplastics In Remote Air: types, concentrations and size distribution) is a measurement campaign of the Institute for Marine and…

Successful student internship at SBO
Successful student internship at SBO

I am Julia Wenske, currently studying in the 2nd master's semester Earth Sciences at the Friedrich Alexander University Erlangen-Nuremberg and I had the unique opportunity to complete an internship for 2 weeks at the Sonnblick Observatory at 3106 meters above sea level. In the period from 26 July to 9 August 2021, I was allowed to look behind the scenes and look over the shoulders of the…
