Soil nitrogen turnover and N₂O emissions in permafrost landscapes of Northern China in a changing climate

The NIFROCLIM project is jointly funded by DFG and NSFC. The central goal of NIFROCLIM (soil nitrogen turnover and nitrous oxide emissions in permafrost landscapes of Northern China in a changing climate) is to gain a holistic, process-based and functional understanding of the gross nitrogen turnover as well as associated nitrous oxide (N2O) emissions for the main ecosystems present in the permafrost region of Northeast China by using an interdisciplinary approach involving biogeochemists, soil scientists, atmospheric physicists, biologists and molecular ecologists. Thus, NIFROCLIM aims at a strong contribution towards closing the large knowledge gaps on permafrost nitrogen biogeochemistry. Furthermore, NIFROCLIM is seen as a platform for international research on permafrost carbon and nitrogen biogeochemistry in China and beyond.




The second campaign in Mohe

Despite the Covid-19 pandemic, a field campaign at the Mohe permafrost site took place at the end of the growing season in 2020, supported by extraordinarily warm temperatures. Within the campaign, Prof. Liu was working on a...[mehr]


Mosses and lichens

Although the temperature in Mohe was below -20 °C in November 2019, mosses and lichens could still be found in the field. Some cyanobacteria associated to them potentially fix atmospheric nitrogen (N2) and thus increase nitrogen...[mehr]


A new cooperation with Prof. Heinz Rennenberg (Southwest University, Chongqing) introduces further highly acknowledged expertise to NIFROCLIM

In November 2019, Michael Dannenmann and his new PhD student in the project, Elisabeth Ramm, flew to Chongqing (China) together with Chunyan Liu to meet Heinz Rennenberg, the founding director of the recently established Center...[mehr]


Intensive GHG flux measurements at the Mohe sites

To address landscape-scale flux variations, Chunyan Liu and his team conduct intensive greenhouse gas (GHG) flux measurements with over 100 flux chambers at sub-daily to sub-weekly temporal resolution at all sites in a catchment...[mehr]
