遥感积雪数据可以提供比有限的地面观测更广泛的积雪时空信息，而MODIS积雪产品是其中应用最为广泛的。该产品基于网格雪冰指数（NDSI）阈值法来判断积雪，即若NDSI值≥NDSI阈值则判定该网格为积雪覆盖。最近，NASA发布了MODIS积雪产品第6版（简称V6），以替代之前的V5版本。与V5相比，V6做出了一些重要更新，包括：（1）V6中的Aqua产品使用重建的波段6，而V5使用的是波段7来替代计算...

蓝藻水华水体在近红外波段具有明显的植物特征“陡坡效应”，是卫星监测蓝藻水华的主要依据。水生植物拥有与蓝藻水华类似的光谱特征，在光学遥感影像上，基于近红外陡坡效应所研发的遥感监测方法，无法实现蓝藻水华和水生植物的同步监测。通常情况下，由于太湖水生植被主要分布在镇湖湾、光福湾、胥口湾、东太湖等区域 ，区别于水华易发区（太湖西部和北部），太湖蓝藻水华遥感监测通常将东太湖水生植被区进行掩膜处理，掩膜区不再...
