At the Leipzig Institute of Meteorology we use global climate and weather models but also airborne, ground-based observation data as well as satellite data. We use the data to study theprocesses that govern the weather and climate in the troposphere, middle and upper atmosphere.
Airborne and Ground-Based Observations
We apply spectral and multi-band imaging and non-imaging techniques:
Spectral Modular Airborne Radiation measurement system
COmpact Radiation Measurement System (ground-based version of the SMART-albedometer)
- Imaging sprectrometers
- Polarization camera
- Imaging thermal infrared cameras
VARIOSCAN 3021 ST, XENICS GOBI-640-GIGE
Video In Situ Snowfall Sensor (VISSS)
These airborne and ground-based instruments are used to:
- measure the solar and terrestrial radiation, and
- to study the effects of clouds and surface propoerties on the atmospheric radiation budget.
We use active remote sensing techniques (cloud radar, rain radar, wind-lidar), and a passive microwave radiometer.
- Active remote sensing techniques
Cloud radar – 94 GHZ FMCW Doppler Cloud Radar (LIMRAD94)
Micro rain radar – MRR-PRO (LIMRAD24)
Doppler-Lidar – Leosphere Doppler Wind Lidar (LIMCUBE)
Doppler-Lidar – Stream Line XR
Lidar – Ceilometer 15K
- Passive remote sensing techniques
Mirkowellenradar – Humidity and Temperature Profilers (HATPRO)
Laser precipitation monitor
Active and passive remote sensing techniques are applied to quantify highly-resolved atmospheric properties of e.g., clouds, precipitation, water vapour, and wind.
The Leipzig institute for meteorology performs climatological observations of the middle atmosphere at the Collm Observatory.
Remote sensing measurments by a VHF meteor radar allow:
- the quantification of the horizontal wind and temperature in the moesopause region (80 - 100 km altitude), and
- the observation of meteors and their properties.
To study global atmospheric linkages we use data of:
- geostationary, and
- polar-orbiting satellite observations.
Based on these measurements, remote sensing products are derived which characterize aerosol and cloud properties.
For example, state-of-the-art retrievals of concentrations of cloud condensation nuclei and ice nucleating particles were developed.
We work with different climate and weather models
- to describe cloud and aerosol processes in the troposhere, and
- to analyze the dynamics of the middle and upper atmosphere.
For that purpose, we use computational capacity at our institute, but also at the German Climate Computing Center (DKRZ).
