Implication

Experimental field evaluation reveals that open-top chambers increase mean daily temperatures by 1.2 to 1.8 °C in polar sites, highlighting their utility for climate change research.

Key Points

To evaluate the microclimatic performance, heating capacity, and potential ecological side effects of passive open-top chambers across polar field environments.
Tested four passive open-top chamber designs across six field sites located in the Arctic and Antarctica.
Monitored environmental variables including ambient and chamber air temperatures, soil temperatures at varying depths, wind speed, global solar radiation, and snow accumulation.
Chambers elevated mean daily air temperatures at four Arctic sites by 1.2–1.8 °C through daytime heating, though occasional nighttime cooling below ambient depressed mean values.
At an Antarctic site with dry soils, no vegetation, and high radiation, chambers increased mean daily soil temperatures by +2.2 °C at –10 cm and +5.2 °C at the surface (0 cm).
Snowmelt timing varied across sites, remaining unchanged at Alexandra Fjord but advancing by 1–2 weeks inside chambers at a deep-snowfall site in Latnjajaure.
