About Johan Scheller

Geographer with 8+ years of experience working with climate data from in situ, satellite, and model sources. I focus on Arctic environments and enjoy working with complex datasets, finding patterns, and turning them into something useful. I like when work makes sense in practice. I enjoy working with others, and I think we get better results when we share knowledge and keep things open. Key strengths o Expertise in climate data – finding trends, extremes, and changes in large datasets o Remote sensing – using satellite and drone data to support monitoring and field work o In situ data – measuring energy and carbon fluxes, setting up and maintaining weather stations in harsh Greenlandic environments o Climate models – often using reanalysis (CARRA, ERA5) when field data is missing o Clear communication – turning technical work into something people can use o Easy to work with – strong in both teamwork and working independently o Efficiency-driven – always seeking simple, effective solutions, often with AI or scripting Technical skills o Python and R for data work o Climate statistics and reporting o Time series and quality control o GIS and spatial tools o Drone data processing o Documentation and metadata o AI tools to sketch out code ideas Current role Climatologist at the Danish Meteorological Institute (DMI, since 2022): o Mapping Greenland’s weather and climate o Building climate data products o Doing quality checks, reports, programming, and workflow improvements Currently on loan to the National Center for Climate Research, also at DMI o Collecting Arctic and Antarctic field data o Helping improve satellite maps and datasets of sea ice and surface temperature Previous experience o 2010-2016: MSc in Physical Geography at University of Copenhagen o 2017–2018: Remote sensing officer at the Danish Agricultural Agency o 2018–2022: PhD and postdoc at Aarhus University – focusing on drone-based methane measurements o 5+ field seasons in Greenland and Northern Scandinavia (10+ campaigns) Ongoing projects o Creating daily weather time series from 1873 until today for Greenland and Denmark o Supporting satellite data validation using real field measurements from the polar regions How I work o Like to find practical solutions and focus on the project goals o Enjoy the mix of operational work and staying science-adjacent o Like teams where people share ideas openly and communicate clearly across roles o Believe work is better when people get along and enjoy working together See some of my publications here:
