为了利用遥感卫星影像资料对湖泊水质进行连续、大范围的监测，以鄱阳湖为研究对象，通过对水体实测高光谱的特征分析，采用分期统计回归的方法建立总悬浮物（TSS）浓度反演模型，利用MODIS影像反演鄱阳湖TSS浓度的空间分布，并分析其时空分布特征。研究结果表明：红光和近红外波段是反演水质参数TSS的敏感波段，在同一环境下分析，可以有效地减少各种内外因素的影响，提高TSS浓度遥感反演模型的适用性和精度，因此...
Using MODIS Images and TRMM Data to Correlate Rainfall Peaks and Water Discharges from the Lebanese Coastal Rivers

Water flows from rivers into the sea (plumes) is a common phenomenon in many coastal zones. The hydro-logic behavior of plumes differs from one river to another depending on rainfall rate and intensit...
An operational method to estimate evapotranspiration using MODIS data during winter wheat growing season
An operational MODIS season

The Penman–Monteith (P-M) model has been widely used to estimate actual evapotranspiration (ET). However, its application is mainly constrained toithin fieldscales because the surface resistance under...
利用美国Terra卫星上MODIS传感器提供的NDVI数据产品，采用两种方法分别在年和月时间尺度上对2000~2007年间洞庭湖的水面面积进行了估算。在年尺度上，采用ISODATA方法对NDVI时间序列进行非监督分类，区分水面及各种湿地类型，并分析了各类湿地的面积变化趋势。在月尺度上，采用16 d平均NDVI数据，通过NDVI阈值提取水面，在不同的季节选取不同的阈值，并将基于NDVI数据得到的水面...
