Four years of continuous measurements.
Our team collected observational data through continuous measurements in the Antarctic Peninsula, spanning from 2022 to 2025. The measurements are focused on the austral summer period, with upcoming expedition and data collection scheduled for February 2026.
Below, you will see multiple types of data we are gathering to enhance our understanding of this unique and extreme environment.
Multidisciplinary datasets
MRR data
Precipitation profiles
At the KSJ station, a vertically pointing K-band (24 GHz) micro rain radar (MRR) was installed providing continuous measurements of vertical precipitation profiles with a vertical resolution of 35 m and a temporal resolution of 1 minute from approximately 100 m to 1 km above ground level.
Biological data
16s rDNA sequences
Using precipitation samples and focusing on a culture-dependant approach, we identified bacterial isolates using 16s rDNA sequencies. The sequencies were used for phylogenetic analysis, and the preserved isolates will be tested for ice nucleating activity.
Radiosonde data
Vertical profiles
Radiosondes with high temporal resolution (every 3-6 hours) were launched during targeted events (including ARs), in addition to the regular radiosondes launched at KSJ station (daily at 12 UTC), to characterize warm/moist air intrusions associated with extratropical cyclones.

Chemical data
Isotope analysis
Snowfall, rainfall and surface snow samples were collected for further laboratory analysis of their stable isotope composition. These observations will be analyzed together with the back trajectories and used to constrain the moisture source and pathways information.
