title: Enhancing the Representation of Glaciers and Ice Sheets in the ecLand Land-Surface Model: Impacts on Surface Energy Balance and Hydrology Across Scales

description: This repository includes data used to produce the figures in the manuscript "Enhancing the Representation of Glaciers and Ice Sheets in the ecLand Land-Surface Model: Impacts on Surface Energy Balance and Hydrology Across Scales" by Arduini et al.

Point simulations

Filename of the archive file containing all simulations: promice_sim.tar.xz

Output is provided in netCDF file, one file for each experiment type and point (station) simulated, organised in sub-folders. See the main manuscript for details on the experimental setup. 

The name convention for the experiment setup is the following "<modelConfig>_exp<Setup>/<stationName>_<iniYear>-<endYear>/", where:



modelConfig: "ctl" for the default control configuration, "glacier_50r1" for the new glacier parameterisation.

stationName: name of the PROMICE site, see the manuscript for more details

iniYear, endYear: initial year and final year simulated per each site.

exp2: corresponds to "OBS" experimental setup in the manuscript

exp3: corresponds to "E5" experimental setup in the manuscript

exp4: corresponds to "E5-CLIM" experimental setup in the manuscript


as an example, CTL-OBS simulations for "TAS-A" station would be under the folder: "ctl_exp2/TAS-A_2013-2022/"; corresponding site and setup for the glacier experiment: "glacier_50r1_exp2/TAS-A_2013-2022/".

For the point simulations at the PROMICE stations, a spin-up procedure was applied. Simulation output files are identified by the suffix “_S<N>”, where N denotes the iteration number of the model run. Only the final iteration was analysed to generate the figures presented in the paper.

The file structure is the following:



o_gg_S<N>.nc : contains prognostic variables, e.g. skin (surface) temperature, snow temperature etc.

o_efl_S<N>.nc : contains the energy fluxes (diagnostic quantities) accumulated over the output step.

restartout_S<N>.nc: the restart file at the end of the iteration, used to initialise the following spin-up iteration.

run_S<N>.log : contains the log of the model run.


2D simulations

control experiment id: ij8z

glacier experiment id: ilhe

Albedo

Albedo for the Greenland ice sheet is provided in a zip file containing daily average broadband albedo for the ctl experiment (ij8z) and the glacier experiment (ilhe). Data are converted to netCDF and interpolated to a 0.25 regular lat/lon grid. One netCDF per year is provided in each zip file.

filename: albedo.zip

Snow temperature

Snow temperature of the top snow layer is used to compute snow melt conditions for the ctl and glacier experiments. 

Filename: snow_temperature.zip

Surface Mass Balance

Surface Mass Balance (SMB) data are provided in grib format on the original grid over the considered time period. 

filename: smb.zip

River discharge

river discharge is provided globally at 15arcmin in netCDF files for the ctl and glacier experiments.

filename: discharge.zip

Observational data

Observation dataset can be obtained or downloaded from the relevant publications listed in the manuscript in Sect. 2.3.
