# Leibniz Institute of Atmospheric Physics (IAP)
|
||
|
||
**Type:** Research institution
|
||
**Location:** Germany
|
||
**Focus:** Atmospheric physics, mesosphere/thermosphere research, LIDAR-based atmospheric monitoring
|
||
|
||
## 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
