Monitoring of near-surface soil temperature in seasonaly snow-covered, mountain ecosystems located in the Mercantour National Park. Data are part of several research projects and monitoring programs examining the impact of climate change on snow cover dynamics, microclimate, species distribution and ecosystem functioning. Data include a GPS position, a date and time in UTC and a near-surface soil temperature (in °C) measured at 5 cm belowground using stand-alone temperature data logger.
