Contents of this archive
README.md
A readme file containing a description of the other files.
automatic_stations_validation_data.csv
Daily data from the automatic weather stations used for validation.
Data sources and providers are listed in the SWE2HS paper, Table 1.
Columns:
* date: timestamp of the format YYYY-MM-DD
* HS_[m]: snow depth in [m]
* SWE_[m]: snow water equivalent in [m]
* site_id: code for the measurement site
- HS_interpolated: boolean flag for interpolated values
- SWE_interpolated: : boolean flag for interpolated values
coordinates_swe2hs_paper_stations.csv
Coordinates of all measurement sites used in the SWE2HS paper.
Columns:
* site_id: code for the measurement site
* location_name: location name of the measurement site
* lon_[wgs84]: longitude in WGS84
* lat_[wgs84]: latitude in WGS84
* elevation_[m]: atitude of the measurement site in [m]
* dataset: dataset in which the station is included
manual_station_calibration_data.csv
Calibration data from the Swiss manual observer stations. Long station records trmmed to 15 random water-years.
Columns:
* date: timestamp of the format YYYY-MM-DD
* HS_[m]: snow depth in [m]
* SWE_[m]: snow water equivalent in [m]
* SWE_from_profile_[m]: biweekly measurement from the SWE in the measurement
pit. Corrected with the bulk density in order to match the snow depth from
the measurement stake. Please refer to the paper for further details.
* site_id: code for the measurement site
manual_stations_validation_data.csv
Validation data from the Swiss manual observer stations. Remaining water-years from the long sttaion record not used for the calibration data.
Columns:
* date: timestamp of the format YYYY-MM-DD
* HS_[m]: snow depth in [m]
* SWE_[m]: snow water equivalent in [m]
* SWE_from_profile_[m]: biweekly measurement from the SWE in the measurement
pit. Corrected with the bulk density in order to match the snow depth from
the measurement stake. Please refer to the paper for further details.
* site_id: code for the measurement site
manual_stations_used_deltasnow_parameters.csv
Site specific DeltaSNOW model parameters used for the calculation of the daily SWE series in 'manual_stations_calibration_data.csv' and 'manual_stations_validation_data.csv'.
Parameters were optimized by reducing RMSE to the biweekly snow pit SWE measurements. Please refer to the paper for further details.
A python implementation of the DeltaSNOW model was used for the calculation: pydeltasnow (https://pypi.org/project/pydeltasnow/)
For a detailed description of the DeltaSNOW model parameters please see the respective publication:
Winkler, M., Schellander, H., & Gruber, S. (2021). Snow water equivalents exclusively from snow depths and their temporal changes: the Δ snow model. Hydrology and Earth System Sciences, 25(3), 1165-1187.
Columns:
* site_id: code for the measurement site
* rho_max: Maximum density of an individual snow layer produced by the DeltaSNOW model in [kg/m3]
* rho_null: Fresh snow density for a newly created layer [kg/m3
* c_ov: Overburden factor due to fresh snow [-]
* k_ov: Defines the impact of the individual layer density on the compaction due to overburden [-]
* k: Exponent of the exponential-law compaction [m3/kg]
* tau: Uncertainty bound [m]
* eta_null: Effective compactive viscosity of snow for “zero-density” [Pa s]
