SMOS satellite hovering over the Earth


Welcome to CLIMERS

We, the Climate and Environmental Remote Sensing Research Unit (CLIMERS) of the Department of Geodesy and Geoinformation (GEO), are committed to Earth system science based on Earth observation technology for the benefit of society and the environment. 

[Translate to English:] Illustration of the Earth's spheres


The Earth system can be divided into four spheres. The lithosphere, which refers to the Earths outer shell and all its solid, mineral constituents; the atmosphere, which comprises all gaseous layers between the Earth surface and the planetary boundary; the biosphere, which refers to the Earth's ecosystems that are inhabited by plants, animals, and any other living organisms; and the hydrosphere, which refers to water on Earth in all its phases. These spheres are intricately linked through the water, carbon, and energy cycles. Climate change is altering these cycles and anthropogenic activities are accelerating climate change at an unprecedented speed. This is leading to an increase in extreme weather events, threatening food security, and exacerbating poverty.

At CLIMERS, we aim to address pressing issues of the Anthropocene by using satellite remote sensing technology to produce long-term datasets of various Earth system variables. Our particular focus is the observation of  soil moisture and vegetation, and to use them in synergy with numerical models and artificial intelligence to conduct global-scale research on how climate change impacts water availability, vegetation growth, and fire danger.
