Atmospheric Research in Wuppertal: Currently running projects

Joint project ISOVIC (influence of solar, volcanic and internal variability on the climate)

An improvement of uncertainties in the prediction of climate change in the next decades is crucial especially regarding political measures for adaptation and mitigation strategies. Besides very specific sources of uncertainties such as changes in radiative forcing due to clouds and aerosol particles or changes in small and large-scale dynamical processes in a warming world a deeper knowledge of possible natural variations and the impact of internal and external forcing is of major importance.[more]


For scientific missions on board the new German research aircraft HALO (High Altitude and Long Range Research Aircraft) the air sampler MIRAH (Measurements of Stable Isotope Ratios in Atmospheric Trace Gases on HALO) shall be installed in the baggage compartment.

During the flight ambient air is collected in 24 SulfinertTM-coated containers. After the flight the air samples are analysed for the isotope ratio in Volatile Organic Compounds (VOC) in our laboratory.

In October 2010 the maiden flight of MIRAH took place during the TECHNO mission. [more]


For the investigation of gravity waves in the atmosphere, a special Spatial Heterodyne interferometer was developed to measure the airglow at 762 nm between 60 km and 120 km. AtmoSHINE (Atmospheric Spatial Heterodyne Interferometer Next Exploration) is the first test mission on a Chinese technology satellite, which was successfully launched from the Jiuquan space station on 22 December 2018, 0:51 CET.

The GRound-based Infrared P-Branch Spectrometer (GRIPS) located in Wuppertal is used by our research group to determine the temperature of the mesopause at an altitude of 87 km (+/- 2 km) in "every" night. GRIPS is a Czerny-Turner grating spectrometer that scans the near infrared between 1.52 - 1.55 micrometer with a spectral resolution of about 450. Measured parameters are the nighttime hydroxyl Meinel band (3,1) rotational temperatures from the [OH*] emission layer. Operating since 1980, more than 3500 nightly mean temperatures have been measured. [more]


The Development Initiative for Small Satellites Exploring Climate Processes by Tomography (DISSECT) was started by the University of Wuppertal and the Research Centre Juelich for the developement of small satellites for climate research to perform temperature measurements of the middle and upper atmosphere. Based on the 6U CubeSat form factor, the payload consists of a telescope with a spectrometer for the observation of airglow, namely O2 atmospheric band emissions at 764 nm. [more]


The High Altitude Gas Analyzer is an aircraft-based fast gas chromatograph for simultaneous in-situ measurements of trace gases like N2O, SF6, CH4, H2 as well as several halogen compounds in combination with an infrared sensor for CO2 measurements in the stratosphere.

Hagar was deployed on board the high-altitude research aircraft Geophysica during many measurement campaigns. From January till March 2010 HAGAR participated in the international RECONCILE campaign in Kiruna/Sweden.


The atmospheric physics research group cooperates with the DLR (Deutsches Zentrum für Luft- und Raumfahrt) to realize the PERflourocarbon TRAcer System (PERTRAS). This project aims for the following of air masses in Lagrangian experiments with the High Altitude and Long Range Research Aircraft  (HALO). First air masses will be marked with artificial tracers (perflourocarbons (PFC)). Afterwards these air masses can be “found again” by in-situ measuring atmospheric PFC concentrations.

A PFC release unit has already been constructed and successfully tested by the DLR. At the moment a multi-channel gas chromatograph for the measurement of PFC as well as natural tracers is being developed in our reasearch group.

Completed projects


The CRyogenic Infrared Spectrometers and Telescope for the Atmosphere - New Frontiers (CRISTA-NF) instrument is designed to study trace gas distributions (H2O, O3, N2O, F11) in the Upper troposphere / Lower stratosphere (UTLS). The  instrument comprises of a Helium-cooled infrared telescope and two grating spectrometers based on the former space telescope CRISTACRISTA-NF is deployed on board the Russian high-flying research plane GEOPHYSICA.

From the beginning in 2005 the instrument has successfully been operated on over 30 flights. So far CRISTA-NF participated in the international campaigns SCOUT-O3 in Australia (Nov./Dec. 2005), AMMA in West Africa (Aug. 2006) and RECONCILE in Kiruna/Sweden (Jan.-Mar. 2010). [more]

GLORIA BlackBody (GBB)

In order to calibrate the GLORIA infrared interferometer with high accuracy, well-defined radiance sources are needed. A calibration system consisting of two blackbodies at different temperatures has been designed and built and tested at our institute.

The high precision characterization of the blackbodies has successfully been performed at the national metrology institute of Germany  PTB in Berlin.


CRyogenic Infrared Spectrometers and Telescopes for the Atmosphere (CRISTA) was a scientific instrument  developed by the University of Wuppertal for studies of small-scale structures in the atmospheric trace gas distributions, which performed very successfully during two Space Shuttle flights in November 1994 and August 1997.
