极地冰盖积累率的时空变化对解释地表高程测量和确定质量输入是重要的。从冰芯和雪坑测量累积率的传统方法提供的空间采样不足。需要遥感方法来获得足够的覆盖范围。我们一直在探索使用高分辨率雷达映射浅内部积雪层在广泛的arcas结合在现场信息的雪密度和化学生成的积累率。
AhtractSpatial and temporal variation of accumulation rale over polar ice sheets is important to interpreting surface elevation measurements and in determining the mass input. Traditional methods of measuring accumulation rate from ice cores and snow pits provide insufficient spatial sampling. Remote sensing methods are required to obtain sufficient coverage. We have been exploring the use of high-resolution radars for mapping shallow internal snow layers over wide arcas in conjunction with in situ information on snow density and chemistry for generating the accumulation rate.
