| 英文摘要 | Snow reflectance in the visible region of the electromagnetic spectrum depends on the amount and type of pollutants. The size of snow grains is important for determining snow albedo, snow thickness using microwave techniques, the thermal environment within the snowpack and, also, for detecting signs of snow melt and snowfall. This chapter summarizes the optical remote sensing techniques used for estimating snow grain size, snow albedo and level of pollution, using spaceborne observations. It focuses on the theoretical background of snow grain size and albedo/pollution monitoring using spaceborne observations. The presented results can be also used for the interpretation of optical airborne and ground-based observations of snowfields and the cryosphere in general. The soot concentration and snow grain size are usually found using two approaches: 1) look up table (LUT) and 2) asymptotic theory. © 2015 by JohnWiley & Sons, Ltd. All rights reserved. |
