Abstract

Using a balance model of the snow layer, we estimate the concentration of black carbon (BC) in the snow; then, with the help of radiative transfer model SNICAR, we calculate the snow albedo and radiative forcing (RF) from snow darkening with BC. Data from an ensemble simulation with INMCM5, the 5th version of the climate model of Marchuk Institute of Numerical Mathematics, Russian Academy of Sciences for the period 1998–2002 are used as input, which include snow both on land and on sea ice. The regionally averaged results are compared with other model data and field measurements.

利用气候模型数据估算黑碳雪变黑带来的辐射强迫

摘要

使用雪层的平衡模型，我们可以估算雪中黑碳（BC）的浓度。然后，借助辐射传递模型SNICAR，我们通过BC的降雪计算了雪的反照率和辐射强迫（RF）。输入的数据来自INMCM5，这是1998年至2002年俄罗斯科学院Marchuk数值数学研究所的气候模型的第5版，它是输入数据，其中包括陆地和海冰上的积雪。将区域平均结果与其他模型数据和现场测量结果进行比较。
