Precise remote sounding for better climate models

The water budget of the troposphere, the bottom layer of the Earth's atmosphere, determines the weather and plays a central role in climate change. The isotope composition of water vapor, i.e. the ratio of light and heavy water molecules, provides insight into underlying mechanisms. Climate researchers gather the data required by in-situ measurements as well as by using remote sounding instruments, e.g. on board of satellites. In a recent campaign, they combined both methods and proved the precision of remote sounding measurements for the first time.

First gasoline produced by the bioliq biomass pilot plant

The synthesis stage of the bioliq pilot plant successfully started operation. Now, all stages of the bioliq process, i.e. flash pyrolysis, high-pressure entrained-flow gasification, and synthesis, have been realized. The project will now be completed by testing the entire process chain and optimizing it for the large industrial scale.
