Down to Earth The First-Class Data Services for FAIR Land-Atmosphere Interaction Research (FLAIR) Project

NFDI4Earth Plenary Session22nd September 2025 Down to Earth The First-Class Data Services for FAIR LandAtmosphere Interaction Research (FLAIR) Project Prof. Dr. Volker Wulfmeyer, Prof. Dr. Matthias Mauder, Dr. Astrid Zeimann, Jonathan Minz NFDI4Earth Plenary Session22nd September 2025 Interdisciplinary evaluation of diurnal to seasonal L-A feedbacks via unique synergistic observations and model simulations over meter to kilometre scales DFG 5639 - Land Atmosphere Feedback Initiative (LAFI) Figure: Illustration of Land –Atmosphere (L-A) feedbacks that will be evaluated in LAFI Land Atmosphere Feedback Observatory (LAFO) Combined ground-based cosmic ray, fiber-optic distributed, water isotope, in-situ, and scanning active remote sensing to measure subsurface, surface land cover and atmospheric variables. Research data management challenge Standardize, document and publish heterogenous datasets via online data repositories and a web –portal, in compliance with FAIR principles. Land Atmosphere Interaction Research NFDI4Earth Plenary Session22nd September 2025 FAIR RDM for L–A Feedback research FLAIR: a model for interdisciplinary, high-quality RDM in ESS, lowering barriers for collaboration and promoting open, reusable, community-driven data practices, and contribution to NFDI4Earth Commitment by integrating LAFI with NFDI4Earth’s Service Portfolio. FLAIR oLAFI data discovery via persistent IDs, OneStop4All and obs4MIPs/ESGF. oRESTful API system or web-portal for direct access to standardised LAFI project data. oSoftware tools & Utilities published and maintained using Gitlab/Github. oOffer tutorials for scripts and workflows through EduHub. oDocument best practices for data conversion, community data standards and FAIR RDM workflows using Living Document. Key features NFDI4Earth Plenary Session22nd September 2025 Ex: Doppler Lidar (DL) data standardization oContinuous wind measurements in a variety of measurement modes, made at LAFO using HALO Streamline Doppler Lidars since 2017 (Inset 1). oDL measurements (Inset 2) output from machine in proprietary text format (.hpl files). oLiaised with Climate Framework (CF) and Observation for Model Intercomparison project (obs4MIPs) to develop Python scripts for creating compliant netCDF files. oScripts, documentation, and HOW – TO’s available on LAFI data management Gitlab repository (Inset 3). Conversion of DL data into CF conformal netCDFs 1 2 3 NFDI4Earth Plenary Session22nd September 2025 Ex: Quality Controlling converted netCDFs onetCDFs should conform to CF conventions and obs4MIPs meta data standards. oPython script uses CEDA’s cf-checker utility to automatically validate netCDFs and summarise results (Inset 1). oSuccessfully tested on data sample from meteorological observations from the MOL-RAO tall tower (Inset 2). oobs4MIPs validation under development in collaboration with the obs4MIPs steering group. oScript, documentation, and HOW – TO’s available on LAFI data management Gitlab repository Validating MOL - RAO netCDF data 1 2 NFDI4Earth Plenary Session22nd September 2025 Thank you for your attention !
