Jinglan Fu is jointly affiliated with the University of Groningen and Karlsruhe Institute of Technology (KIT), where her research focuses on understanding chemical processes in our atmosphere. In her interview she discusses the chamber study she has worked on, where she aims to simulate real atmospheric conditions inside a massive stainless steel chamber, and how within the campaign she has worked together with TROPOS to collect cloud particles to study their chemical composition.
Strategic atmospheric infrastructure at the edge of land and sea
At the northern edge of the Netherlands, where the mainland meets the Wadden Sea, lies the Lutjewad measurement station – an essential node in the national and European system for atmospheric monitoring...

Last campaign days!
Last campaign days!
28 April 2025
With the campaign over, the time has now come to pack up the campaign instruments and ship them back to their respective institutes. It has been over a month of hard work and many measurements and the data analysis can start now! Some instruments will be staying at Cabauw and Lutjewad for longer term measurements, the instruments staying at Cabauw have been moved to our container.
Last ACTOS flight
Last ACTOS flight
27 April 2025
Today was the last ACTOS flight. During the campaign there have been as many flights as possible under many different conditions: clear skies, flying under the clouds, but of course also flights in the clouds!
Container arrives at Cabauw

25 April 2025
The campaign is almost over, however a small number of instruments will be staying at Cabauw for longer term measurements. Due to planned maintenance of the Cabauw tower, the instruments cannot in the tower itself, which is why they will be moved to a container on the remote sensing site. Today the container arrived!

14 April 2025
After multiple flights where there were no clouds, or it was not possible to fly above the coulds, today was the first day where ACTOS was able to sample the clouds! In total two flights were done today and it was possible to sample the clouds and even collect some cloud water in both flights!

CCN arrives at Cabauw
CCN arrives at Cabauw
9 April 2025
After a short detour to the UK, the size-resolved CCN from the Cyprus Institute has finally arrived at Cabauw. It has been set up as soon as possible to start the measurements!
Cloud condensation nuclei (CCN) are the aerosols which can form cloud droplets. With the size-resolved CCN, measurements on CCN activity can be done; the ability of aerosols to serve as cloud condensation nuclei.
IMT Nord drone flights
IMT Nord drone flights
8 April 2025
The team from IMT Nord has been flying their drone for the whole week, having had some intensive sampling days. All sampled cannisters have been measured and we're looking forward to the insights the analysis of the data will bring and add to the campaign!
ACTOS setting up at Eemshaven
ACTOS setting up at Eemshaven
3 April 2025
Earlier this week the team from TROPOS that will be running the ACTOS arrived at Eemshaven. They're busy setting up the ACTOS to be ready to fly. ACTOS (Airborne Cloud Turbulence Observation System) is carried as an external cargo 140 m below a slow-flying helicopter, from where be immersed into individual clouds and conduct measurements in the cloudy boundary layer.
Today the helicopter that will be used to carry ACTOS during these measurements arrived at Eemshaven, so hopefully test flights can start soon and, clouds permitting, measurements can start soon after that!
Setting up the PSM in Lutjewad

2 April 2025
The PSM from TROPOS was set up in Lutjewad today!
The PSM will be able to do continuous measurements measurements of the smallest particle clusters in the size range of 1 to 4 nm, spanning the transition from gas to particle and the initial stages of aerosol phase growth.

Today the team from IMT-Nord arrived at Cabauw. IMT-Nord will be utilising drones to sample cannisters at different heights near the towers, the VOCs in these air samples are analysed using the PTR-MS from University Utrecht that is already on site for continuous measurements!
The team from IMT-Nord has unpacked their drone and started doing some test flights!
Placing the Api-ToF
Placing the Api-ToF
31 March 2025
This day, the team at Cabauw tackled one of its largest challenges, placing the Api-Tof. Due to its measurement method, it needs an as short as possible inlet, for this, the instrument needs to be place on an elevated platform to reach the windows in the main building at Cabauw. This lead to the challenge of lifting a sensitive instrument, weighing 250 kg, onto a platform of 1.5 meters high. With the help of a lift, and a lot of people power, the team was able to do it and the Api-ToF is in its proper place, ready to start measuring!
Cyprus Institute instruments arrive at Cabauw

Setting up the first instruments!
Setting up the first instruments!
17 March 2025
Today the first instruments were moved to Cabauw!
The team from MPIC-Mainz drove from Mainz with a van filled with instruments ready to be placed in the basement at the 60m inlet line. The ALABAMA, AMS, UHSAS, CPC, and MAAP from MPIC were all moved down, where the team started installing the instruments.
Additionally, a team from the University of Groningen drove to Cabauw to bring a high volume filter sampler and an automatic filter sampler. The high volume filter sampler was placed outside, ready to be callibrated and set up later in the week and the automatic filter sampler from KIT was moved to the basement as well to be placed at the 60m inlet line.
ACSM at 180m!
ACSM at 180m!
13 March 2025
The ACSM from Utrecht University has been moved to 180 meter, ready for the field campaign to start next week!
The ACSM has already been measuring on the ground for a couple months now to test it out, make sure it is stable and prepare it to be placed at 180m. After a test of measuring outside in the custom build case, all kinks have been worked out and the ACSM was ready to be moved up to 180m.
