Pictures of the Month 2023

An ISSI (International Space Science Institute) International Team led by Dr. Maria N. Drozdovskaya (Center for Space and Habitability, University of Bern) and Dr. Cyrielle Opitom (University of Edinburgh) visited the research station Jungfraujoch to hold a meeting in the library and to have a guided tour around the station and the Sphinx-observatory.

As part of the celebration activities of the EuChemS Historical Landmark Award 2021 that was awarded to the High Altitude Research Station Jungfraujoch, invited guests travelled to Jungfraujoch to reveal the original plaque (from left to right: Prof. Markus Leuenberger, Director HFSJG, Prof. Silvio Decurtins, President HFSJG, Prof. Floris Rutjes, President EuChemS, Dr. Brigitte Van Tiggelen, representative of the Historical Landmark Committee of the EuChemS).

FAU Erlangen used a drone-based radar system to investigate stratification in firn and ice. The ultra-wideband FMCW radar system can resolve stratifications in the order of a few cm at a depth of several tens of metres. The picture shows the octocopter on a measurement flight in front of the impressive panorama of the Jungfrau (picture on the top).A field test camp was set up on the Jungfraufirn by FAU Erlangen, BU Wuppertal and RWTH Aachen for melt drilling in the glacier. The melting probe is additionally equipped with radar, sonar and permittivity sensors in order to be able to draw conclusions about the stratification in the glacier. In addition, the camp is used as a starting point for measurements with mobile radar equipment. The team carried out measurements on the Jungfraufirn over a period of 3 weeks in March/April 2023 (picture on the bottom).Pictures: © LHFT, FAU Erlangen-Nürnberg
Visitor groups at Jungfraujoch:The team of the Environmental Research Station Schneefernerhaus at the Zugspitze, Germany visited our custodians and the research station (picture on top).The management of MeteoSwiss also enjoyed a tour through the Sphinx-observatory and the research station (picture on the bottom).Pictures: HFSJG
A novel air sampling system was recently installed under the roof of the research station at Jungfraujoch. It will allow the automatic sampling of background air only during nighttime, when the station is mostly situated in the free troposphere, and thus avoid air masses influenced by more local fluxes that can rise until the station at daytime, especially during summer. Every two weeks, the air sampled in this way is transferred into a bag and transported back to the University of Bern for 14CH4 and 14CO2 analyses. Picture: DCBP/University of Bern
The University of Milano-Bicocca, Italy, wants to experimentally determine the atmospheric heating rate due to light absorbing aerosols. Their instrument is installed on the upper Sphinx-terrace, safely guarded by the jackdaws. Picture: HFSJG
A delegation of the Peking University, College of Environmental Sciences and Engineering, visited the research station at Jungfraujoch and was given a tour (picture on top). In the afternoon, an international workshop with researchers from the Peking University, Paul Scherrer Institute, Empa, University of Helsinki and HFSJG was held in the library of the research station (picture on the bottom). Pictures: HFSJG
On occasion of the HFSJG Board Meeting in Zermatt, the board members and guests participated in an excursion to the Gornergrat by beautiful and sunny weather. The group visited the Stellarium Gornergrat and listened to talks about glaciology and geology. Picture: HFSJG
Impressions of the measurements of firn accumulation on Grosser Aletschgletscher of the GLAMOS program (Swiss glacier monitoring). Twice a year in spring and fall, the gain in glacier mass is determined by firn drilling down to the marked horizon of the end of summer surface of the previous year. Pictures: HFSJG
Our technician, Dr. Lukas Bäni, on the roof of the East Ridge building. With the help of the company Seiler AG, a sensor on the weather station (picture on the left) was replaced. Pictures: Seiler AG
