The paper “PROMICE and GC-Net automatic weather station dataset for the Greenland Ice Sheet” by Fausto et al. (2026), published in Earth System Science Data, presents a comprehensive and harmonized dataset from the PROMICE (Programme for Monitoring of the Greenland Ice Sheet) and GC-Net (Greenland Climate Network) automatic weather station networks. These long-term observational systems provide critical in situ measurements across the Greenland Ice Sheet, supporting a wide range of glaciological and climate research.
The dataset integrates high-quality observations of key atmospheric and surface variables, including air temperature, humidity, wind speed, radiation fluxes, and surface height changes. By combining multiple monitoring efforts into a unified and consistently processed data product, the study significantly enhances accessibility and usability for the scientific community. Importantly, the inclusion of GPS measurements allows for tracking ice motion, offering valuable insight into ice dynamics alongside surface mass balance processes.
With records spanning more than a decade at several sites, this dataset represents one of the most robust observational foundations for understanding ongoing changes in the Greenland Ice Sheet. It plays a crucial role in improving climate model performance, validating satellite-derived products, and refining projections of future sea-level rise.
The work also highlights the importance of sustained international collaboration in polar research. The LIQUIDICE project contributed to this effort by supporting activities related to data treatment routines, as acknowledged by the authors. This contribution aligns with LIQUIDICE’s mission to advance understanding of ice-climate interactions and their implications for the Earth system.
