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...

准确估算烟田生态系统生产力，对于评估区域烟叶产量的时空变化特征及研究烟叶产量的影响因素至关重要。采用遥感数据和地面通量观测数据，对MODIS生产力模型在攀西烟区典型烟田生态系统总初级生产力（GPP）评估中的适用性进行初步验证和本地参数化，以提高MODIS数据产品在攀西烟田生产力水平评价中的可信度。结果表明：采用默认参数的GPP模拟值低于观测值，1：1直线回归斜率为0.769，决定系数（R2）为0....
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...
