The Jungfraujoch research station is ideally suited for continuous measurements and intensive field experiments in a high-altitude environment. The site is ideally suited to investigate i) composition and processes in the lower free troposphere, ii) properties of liquid and mixed-phase clouds and their interactions with aerosols and trace gases. iii) aged pollution and long-range transported plumes. External research groups are invited to bring their own equipment complementing the broad range of already existing observations. The research groups operating the continuous monitoring at Jungfraujoch can also provide additional research equipment for intensive experiments.

The service includes:

• Support in aligning the experiment design with research questions and local conditions.

• Support in data interpretation in context of the peculiarities of the remote high-altitude environment.

•  Logistical support for the entire life-cycle of the experiment.

• Lab facilities and outdoor platforms.

• Accommodation at the research station operated by the foundation High Altitude Research Stations Jungfraujoch & Gornergrat (https://www.hfsjg.ch/en/home/).

The free tropospheric air masses (low concentrations), high altitude (low pressure), cold temperatures (for outdoor instruments), frequent clouds (including supercooled liquid and mixed-phase clouds) pose many challenges for research equipment and often require adaptation of calibration, operation and data processing procedures. These boundary conditions, along with a comprehensive suite of continuous observations of many atmospheric variables (https://www.actris.ch/) make the site an ideal platform for testing performance of new and specifically adapted equipment, as well as for training of instrument operators.

The service includes:

• Support in preparing the experimental setup for instrument testing.

• Training for calibration and operation of research equipment under the high-altitude conditions.

• Provision of reference data from established observations.

• Lab facilities and outdoor platforms.

• Logistical support

• Accommodation at the research station operated by the foundation High Altitude Research Stations Jungfraujoch & Gornergrat (https://www.hfsjg.ch/en/home/).
