Overview
The Leibniz Institute of Atmospheric Physics is a leading European atmospheric research center specializing in upper atmosphere physics and remote sensing technologies.
Key Research
Satellite Reentry Atmospheric Pollution Detection (2026)
Research team led by Robin Wing achieved the first direct empirical detection of satellite reentry atmospheric pollution using ground-based LIDAR systems. The team detected a 10× background lithium plume at 100km altitude from a SpaceX Falcon 9 upper stage reentry, published in Communications Earth & Environment (Nature portfolio journal) in February 2026.
Methodology:
- Ground-based LIDAR measuring fluorescence of trace metals in mesosphere/thermosphere
- Trajectory tracking to correlate atmospheric signatures with specific reentry events
- Real-time detection capability for spacecraft combustion products
Significance:
- First real-time observational evidence linking specific spacecraft reentry to measurable atmospheric chemical signature
- Methodologically novel combination of LIDAR sensitivity, trajectory analysis, and event correlation
- Closes evidentiary loop from atmospheric modeling to direct observation
