Abstract
Abstract. Assessing changes in the density of snow and firn is vital to
convert volume changes into mass changes on glaciers and ice sheets. Firn
models simulate this process but typically rely upon steady-state
assumptions and geographically and temporally limited sets of field
measurements for validation. Given rapid changes recently observed in
Greenland's surface mass balance, a contemporary dataset measuring firn
compaction in a range of climate zones across the Greenland ice sheet's
accumulation zone is needed. To fill this need, the Firn Compaction
Verification and Reconnaissance (FirnCover) dataset comprises daily
measurements from 48 strainmeters installed in boreholes at eight sites on
the Greenland ice sheet between 2013 and 2019. The dataset also includes
daily records of 2 m air temperature, snow height, and firn
temperature from each station. The majority of the FirnCover stations were
installed in close proximity to automated weather stations that measure a
wider suite of meteorological measurements, allowing the user access to
auxiliary datasets for model validation studies using FirnCover data. The
dataset can be found here: https://doi.org/10.18739/A25X25D7M (MacFerrin et al., 2021).
