Incoming and transmitted irradiance through snow and sea ice in the Chukchi Sea in August 2019

Incoming irradiance at the surface and transmitted through snow and sea ice was measured during a cruise to the Chukchi Sea in August 2019 with the Korean RV Araon using TriOS RAMSES planar radiometers. The data was collected to improve understanding of how the physical and optical properties of various sea ice conditions affect the solar partitioning by snow and sea ice in the Arctic Ocean and how this might affect the ecosystem trophic levels relying on photosynthesis. The data is also used to improve parameterisation in models or for remote sensing applications in order to upscale to a pan-Arctic level.

This dataset resulted from the NERC project (NE/R012725/1) Eco-Light, part of the Changing Arctic Ocean programme, jointly funded by the UKRI Natural Environment Research Council (NERC) and the German Federal Ministry of Education and Research (BMBF).
