中文摘要: 利用卫星遥感和常规观测的积雪资料，确定了适合业务使用的北半球及中国积雪监测诊断方法，并初步建立了北半球和中国积雪监测业务。其相关业务产品主要有:北半球月积雪日数、中国月积雪日数、积雪深度的分布，北半球、欧亚、中国等不同区域积雪面积距平指数。
中文关键词: 卫星遥感，常规观测，积雪日数，积雪深度，积雪面积
Abstract:Based on remote sensing snow cover data in the Northern Hemisphere and surface observations for snow depth and days with snow cover in China,the monitoring and diagnosing methods for snow cover are studied. An operational system for snow cover in the Northern Hemisphere was set up. The operational products included spatial distribution for days with snow cover in the Northern Hemisphere,snow depth and days with snow cover in China,anomalies indices for snow area,and snow depth and days with snow cover in each region.
