Firn temperature-time series to 15 or 25 meter depth at sites along the west Expéditions Glaciologiques Internationales au Groenland (EGIG) line, Greenland 2024-2025

This archive contains firn temperature data collected at five sites in the western Greenland Ice Sheet percolation zone. The sites are located along a lower elevation transect of the Expéditions Glaciologiques Internationales au Groenland (EGIG) line. The data are time series of firn temperature measured in boreholes drilled to 15 or 25 meters depth. The boreholes were drilled by firn coring methods after which the sensor strings were installed, and the holes were backfilled with fine sifted snow. These measurements are associated with additional datasets collected as part of a National Science Foundation (NSF) Arctic Observing Network project and include measurements at multiple sites on the EGIG line of firn temperature and firn density/ice content.
