MeteoIO and SNOWPACK are software published under the GNU LGPLv3 license by the WSL Institute for Snow and Avalanche Research SLF, Davos, Switzerland at https://gitlabext.wsl.ch/snow-models. The repository used to develop the versions of MeteoIO and SNOWPACK used in this study can be accessed at https://github.com/snowpack-model/snowpack (doi:10.5281/zenodo.3891845) with the exact version corresponding to commit 149c586 (doi:10.5281/zenodo.7331794). The workflow consists of two phases. First, using MERRA-2 reanalysis as forcing, a spinup is performed for the MERRA-2 grid point closest to the AMIGOS weather stations Channel (CHA) and Cavity (CAV). To perform the spinup: navigate to the ./simulations_spinup/ directory edit the following line in the file spinup.rc, to modify the path where the time_shift_script can be found: time_shift_script="/path/to/snowpack/Source/snowpack/tools/timeshift_sno_files.sh" This script can be found in the SNOWPACK repository. Execute the two SNOWPACK spinup simulations specified below. Change the path to point to the SNOWPACK binary executable. The simulations are performed for the two sites, which use the same meteorological forcing, but have a different end date specified for the simulation (corresponding to the installation date of the AMIGOS weather station): bash spinup.sh "/path/to/usr/bin/snowpack -c cfgfiles/THWAITES_CAV.ini -e 2020-01-10T01:00 > log/THWAITES_SPINUP.log 2>&1" startover=1 bash spinup.sh "/path/to/usr/bin/snowpack -c cfgfiles/THWAITES_CHA.ini -e 2020-01-16T01:00 > log/THWAITES_SPINUP.log 2>&1" startover=1 Brief overview of the ...
