Measurement Methods and Models

A range of methods and tools is used across the different working groups research topics. Dynamical, radiative and chemical models are used to understand the processes in the atmosphere. Several measurement instruments, particularly remote sensing methods, allow to observe the atmosphere.

Radiative Transfer

We develop the 3D Model MYSTIC and the modelling package libRadtran, a collection of tools to calculate solar and thermal radiative transfer in the earth's atmosphere.

Numerical Simulations

Several numerical weather models, such as COSMO, ICON or the LES-model EULAG, are used and developed further in various research groups


We develop numerical models to describe morphology, chemical composition, optical properties of aerosol, as well as its interactions with trace gases, radiation and clouds.

Lidar Remote Sensing of Aerosols

We use self-developed, POLIS and MULIS, and commercial LIDAR-Systems for remote sensing of aerosols.

Cloud Spectrometer specMACS

A hyper-spectral spectrometer for the spectral area 400 - 2500 nm, specMACS, is used for remote sensing of cloud properties.

Cloud Radar miraMACS

The scanning Metek MIRA-35 on the roof of our institute uses a wave length of 8 mm and is sensitive to cloud and rain particles. We use it to investigate cloud geometry and microphysics.

Sun Photometer SSARA

Out self-developed sun photometer SSARA measures solar radiation. The MIM is part of the AERONET network.

UV-Radiation: Measurement and Modelling

Solar UV-radiation, important for skin cancer, vitamin D production and photo chemistry, is measured at MIM and on top of the Zugspitze. UV-modelling allows sensitivity studies and prognoses.

Meteorological Tower

The meteorological measurement tower located in the Campus Garching is necessary for the operation of the research reactor. The MIM provides this service for TU since 1961.
