We investigate the complex interaction of chemical and dynamical processes in the Earth's atmosphere on basis of distributions of trace gases, aerosols, clouds and temperature which we derive from spectral measurements of satellite remote sensing instruments. Our work field covers processing of satellite data and their validation, the research on physical and chemical processes in the atmosphere on the basis of the retrieved distributions of temperature, particles and trace gases, and the development and implementation of related satellite data analysis algorithms. The current focus of our work is the MIPAS-Envisat mission. The MIPAS satellite data derived by our group can be accessed here. Besides our work with MIPAS we are involved in the preparation of future space missions. On this website you find information about our publications, MIPAS-Envisat data, the annual MIPAS Data User Meeting, our radiative transfer model KOPRA, the team and our projects, as well as some pictures.
Highlight of the month:
MIPAS HCFC22 data help to validate ground based FTIR HCFC22 measurements from Jungfraujoch station
The figure presents the time series of monthly means of lower stratospheric partial columns (11.2 to 30 km) of HCFC22 measured by ground-based FTIR from Jungfraujoch (black dots are monthly means, the shaded area is the standard deviation of the monthly means). They are compared to MIPAS monthly means of measurements within 500 km around the Jungfraujoch station (blue dots). The blue bars are the standard deviations of the MIPAS monthly means. Also presented are results from two models, BASCOE CTM (green), and WACCM (red). The black line is the regression fit of the black data points which is dominated by a strong increase and a pronounced seasonal cycle.
