Field campaign IMPACT 2024, Finland

Here, we will give a regular update on the field campaign IMPACT - In situ Measurement of Particles, Atmosphere, Clouds and Turbulence - in Pallas, Finland from May 27 to June 16.

The eleven Windarts are assembled in the workshop. Like oversized darts, they will be attached to the rope leading up to the cloud kite. Up there, they will measure various atmospheric parameters. Thanks to their construction, the darts remain stable and can be held in position even in slightly bad weather.

Mohsen Bagheri is one of the coordinators of the field campaign. During this project, also the Max Planck Cloud Kite (MPCK) will fly through the clouds at an altitude of up to 2 kilometers. There, advanced imaging sensors will measure cloud droplets and atmospheric turbulence. This was the scientists will gain insights on cloud formation and lifetime.

The Holo-Track is also used in Finland to study cloud droplets. Birte Thiede makes the final preparations and prepares a component for the measuring apparatus. A laser and a camera are used to measure the position, size and movement of the droplets in the clouds.

Venecia Chávez Medina, Hossein Khodamoradi and Christobal Nieto Gonzales are working on the brains of the eleven windarts. Those will be will be attached to the rope of the Cloudkite are rise up to 2km high. The windarts will measure the main atmospheric quantities such as temperature, pressure, wind velocity in 3 directions as well as the CO2 concentration.

Plant seeds, volcanic ash or cloud ice particles occur in different forms and are distributed in the atmosphere in different ways that cannot be reproduced in the laboratory. To understand the shape-dependent fall behavior, Taraprasad Bhowmick crafts various objects, which will be dropped from a height of 1 to 2 kilometers using a balloon. The objects have the same mass and density, but different shapes and sizes. The idea is to use specially installed sensors to collect data on the flight and fall characteristics of the various objects for further measurements.

Preparations are in full swing. While the cloud kites are being prepared and packed for the trip, the final measuring devices are being checked to ensure that everything works smoothly on site. At the end of May, the scientists set off for the test site around 2,500 km away in a total of three vehicles.
