Spectral transmission and implications for the partitioning of shortwave radiation in arctic sea ice

  • Thomas C. Grenfell (a1), Bonnie Light (a2) and Donald K. Perovich (a3)

Abstract

We present a new set of values for the spectral extinction coefficients, , for the interior of first-year (FY) and multi-year (MY) Arctic sea ice during the summer melt season measured during SHEBA (Surface Heat Budget of the Arctic Ocean program) and at Barrow, Alaska, USA. Results for FY ice are consistent with previously reported values, and differences can be understood in terms of variations in the concentration of biological and suspended particulate material. The values for the interior of MY ice are lower than previously reported for both bare and ponded ice. For bare MY ice the new Kλ values predict a substantial increase in the solar radiation transmitted through the ice into the upper mixed layer. Ponded MY ice is only slightly more transparent than previously reported, and FY ice values are generally consistent with previously reported values. Assuming an asymmetry parameter of 0.94, the extinction coefficients are consistent with a volume-scattering coefficient of 77 m–1 that is constant from 400 to at least 720 nm.
