The department conducts research to tackle global environmental problems and understand global geodynamic processes. Both through measurement technical competence, including measurements from the ground surface, satellite measurements and interpretation of these measurements, as well as modelling. We also develop instruments, applications and analysis methods.
We focus on the following four research areas.
Space Geodesy and Geodynamics
Our research concerns global geodynamical processes. We perform measurements and analyse these to e.g. determine movements in the earth’s crust, earth rotation parameters, the amount of water vapour in the atmosphere, and changes of the gravity field. Primarily we use space geodetic methods such as geodetic very long baseline interferometry (VLBI) and global navigation satellite systems (GNSS), as well as ground based radiometers, and gravimeters. This is augmented by corresponding theoretical work and model calculations. Read more about our research in Space Geodesy and Geodynamics.
Global environmental measurements and modelling
Optical remote sensing
We focus on the study of the composition of the lower levels of the atmosphere through the development and application of optical remote sensing methods. These methods cover spectral ranges from the ultraviolet to the infrared and they are carried out from multiple plaforms on ground, air, and space, to measure the emissions from natural and human made sources. Our research is field oriented and applies to a range of problems, including climate change, ozone layer processes, volcanic degassing and emissions from industries and transport. This work is carried out within large international networks of collaboration. Read more about our research in Optical remote sensing
Radar Remote Sensing
The objective of our research is to gain new knowledge about methods and applications of remote sensing using radar. We develop signal and image processing algorithms, measurement systems and electromagnetic scattering models. Examples of projects include measurements of above-ground biomass and water content of forests, ocean currents, sea ice concentration and motion and small-scale ground motion.
