Deception Island, Antarctica hosts this dataset of hourly snow-pack properties from the Crater Lake CALM site since 2017. It includes air temperature, moisture, radiation, surface and subsurface temperatures at multiple depths, snow depth, weight, water content, ice content, density, and snow water equivalent. The data is part of the PERMATHERMAL monitoring network led by Dr. Miguel Ángel de Pablo of Universidad de Alcalá.
Use Cases
- Model active layer thickness using temperature data from ground surface and depths of 10, 20, 40, 80, and 100 cm.
- Analyze snowpack energy balance using total and IR incident and reflected radiation alongside surface temperature.
- Estimate snow water equivalent (SWE) evolution from snow depth, weight, density, and water/ice content measurements.
- Correlate air temperature and moisture with snow depth and subsurface temperature profiles to study thermal insulation.
Strengths
- Hourly temporal resolution provides detailed diurnal cycle data.
- Multivariate measurements include over 15 distinct physical properties of the snowpack and atmosphere.
- Data collection is part of a long-term monitoring network established in 2000.
Limitations
- The dataset is geographically limited to a single site (Crater Lake CALM A16) on Deception Island.
- The last update recorded is from 2017, indicating potential data staleness.
- Unknown row count and sample size prevent assessment of statistical power.
