2005-present hourly to 4-hourly raw measurements of snow temperature and snow cover depth from nine monitoring stations on Livingston Island, Antarctica. The dataset is part of the PERMATHERMAL network, which monitors frozen ground following GCOS principles and is led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá.
Use Cases
- Analyze temporal trends in snow_depth at specific stations (e.g., Juan Carlos I, Limnopolar Lake) to study seasonal snow cover variability.
- Model the relationship between snow_temperature and air/ground temperature at different sensor depths to understand insulation effects.
- Correlate snow_depth measurements with active layer thickness data from CALM stations to assess permafrost thermal state.
- Use time-series data from multiple PT stations (e.g., Incinerador, Morrena) for spatial comparison of snowpack properties across Hurd and Byers Peninsulas.
Strengths
- Long-term temporal coverage starting in 2005, providing over 15 years of data.
- High-frequency data acquisition at 1 to 4-hour intervals enabling detailed diurnal and seasonal analysis.
- Spatial coverage from nine distinct monitoring stations across two peninsulas on Livingston Island.
Limitations
- Data is described as raw and not processed, which may require significant quality control and calibration.
- Specific row counts, sensor accuracy metrics, and data completeness for each station are unknown.
- Geographic scope is limited to two Antarctic islands, restricting broader regional generalization.
Provenance
- Source
- PERMATHERMAL monitoring network led by Dr. Miguel Ángel de Pablo, Universidad de Alcalá, via NASA Earthdata.
- Collection Method
- Measurements from PT station instruments with sensors for air, surface, ground temperature, and snow depth.
- Time Range
