| 摘 要： | 结合Terra和Aqua卫星的积雪产品,获取2001-2006年全国新的逐日积雪覆盖数据,并利用此数据通过两种方案获取了全国积雪日数分布,对比发现3大稳定积雪区中,新疆地区积雪稳定性及连续性最好,东北其次,而青藏高原地区最差；通过595个气象台站年积雪日数数据分区分不同植被类型修正MODIS获得的年积雪日数.结果表明:...

| Abstract: | New snow cover products are produced by combination of Aqua and Terra MODIS snow cover products from 2001.Then MODIS snow-covered days are produced by this new snow cover products through two standards.Through comparison of these two different snow-covered days all over China,it is found that among the three major snow cover centers,snow cover is more stable in Xinjiang Region than that in the other two regions,including the Tibetan Plateau and Northeast China-Inner Mongolia Region.The MODIS snow cover days... |
