Anne Klosterhalfen

BG Biogeosciences

The 2026 Division Outstanding Early Career Scientist Award is awarded to Anne Klosterhalfen for outstanding contributions to improve measurements and understanding of ecosystem carbon and water fluxes, engagement in collaborative research, and dedication to education and outreach.

The Biogeosciences Division is pleased to select Anne Klosterhafen for the Outstanding Early Career Scientist Award 2026, for her exceptional contributions to improve measurements and advance understanding of land-atmosphere exchange processes, to foster international collaborations, and in educating future scientists. In her career, Anne Klosterhafen has contributed to key scientific advances by addressing core challenges in ecosystem-atmosphere exchange, particularly the partitioning of net ecosystem exchange into photosynthesis and respiration, and of evapo-transpiration into evaporation and transpiration. She introduced an innovative use of high-frequency eddy-covariance raw data, applying a condition sampling approach that goes beyond traditional methods. In addition, she developed a novel framework to correct for biases in eddy-covariance flux estimates caused by differing daytime and nighttime footprint source areas over heterogeneous landscapes, thereby substantially improving the accuracy and interpretation of land-atmosphere exchange measurements. 

In addition to her research, Anne Klosterhafen has made outstanding contributions to promote international collaboration across disciplines. In her role as the long-term scientific coordinator of the Integrated Carbon Observation System (ICOS) Hainich forest’s eddy covariance flux tower since 2021, she has attracted collaborations with European research teams making it a key research infrastructure for studying the carbon cycle, for testing new instruments and for validation of remote sensing products. Furthermore, her continued involvement as convener at the EGU General Assembly for several years, and her recent appointment as an Associate Editor of EGU’s Biogeosciences journal in 2025 further underline her leadership and commitment to the scientific community.
Anne’s commitment to education is equally impressive. She consistently receives top evaluations for her teaching and further extends her educational impact through interdisciplinary art-science initiatives that bring scientific insights to wider audiences in creative and impactful ways.

Taken together, Anne Klosterhafen is a well-rounded, collaborative, and forward-thinking scientist. Her record of innovation, community service, and dedication to education makes her an outstanding choice for this recognition.
