Snow, soil and meteorological data at Bylot Island for simulating the permafrost thermal regime and evaluating output of the SURFEXv8 land surface scheme

Global warming projections still suffer from a limited representation of the permafrost-carbon feedback. Predicting the response of the permafrost temperature to climate changes requires accurate simulations of the Arctic snow and soil properties. The purpose of this project is to assess the capacity of the coupled models ISBA-Crocus and ISBA-ES to simulate snow and soil properties at Bylot Island, a high Arctic site (Barrere et al., 2017). The datasets in this issue of Nordicana D are field measurements complemented with ERA-interim reanalyses (Dee et al., 2011), used to drive the models and to evaluate simulation outputs. The measurement site is part of the stations network of the Center for Northern Studies (CEN, 2016). Meteorological data used as driving input cover the period from 1979-2015 with a 3h timestep. The following variables are includes in the netCDF file: air temperature and specific humidity, wind speed, incoming shortwave and longwave radiation, precipitation rate (solid and liquid) and atmospheric pressure. Evaluation data are available from 2013 to 2015, they include measurements of: snow height (daily values), snow and surface temperatures (one value every two days), soil thermal conductivity (one value every two days), and soil temperature and water content (hourly values).

Variable measured
  • Variable name: Evaluation data  Variable description: Field data used to evaluate simulation outputs of the following properties: snow height (in cm), snow temperatures at 2, 12 and 22 cm (in °C), surface temperature (in °C), soil thermal conductivity at 10 cm deep (in W m-1 K-1), and soil temperature (in °C) and water content (in m3 m-3) at 5, 10 and 15 cm deep. Data are available from August 2013 to June 2015.  Variable unit: unitless
  • Variable name: Meteorological driving data  Variable description: Meteorological data used as driving input to simulate snow and soil properties at Bylot Island. Available from August 1979 to June 2015, they consist in air temperature (K) and specific humidity (g kg-1) at 2 m above ground, wind speed (m s-1) at 10 m above ground, incoming shortwave and longwave radiation (W m-2), precipitation rate (solid and liquid, kg m-2 s-1) and atmospheric pressure (Pa). Air temperature and humidity, and wind speed are from the BylSta station between July 2014 - June 2015. From July 2004 to June 2014, air temperature and wind speed were taken from the SILA tower (CEN, 2016). Missing variables and data gaps were filled with ERA-interim reanalyses data (Dee <i>et al.</i>, 2011).  Variable unit: unitless
