Time-series of snow spectral albedo and superficial snow specific surface area at Dome C in Antarctica, 2012-2015

Spectral albedo has been measured at Dome C since December 2012 in the visible and near infrared (400 - 1050 nm) at sub-hourly resolution using a home-made spectral radiometer. Superficial specific surface area (SSA) has been estimated by fitting the observed albedo spectra to the analytical Asymptotic Approximation Radiative Transfer theory (AART). […]

自2012年12月起，在南极昆仑站对光谱反照率进行了测量，测量范围为可见光及近红外波段（400 - 1050纳米），以亚小时分辨率的精度，使用自制的光谱辐射计进行。通过将观测到的反照率光谱与解析渐近近似辐射传输理论（AART）进行拟合，估算出表观比表面积（SSA）。
