Landsat Surface Reflectance for Great Salt Lake, Utah Lake, and Farmington Bay

Surface reflectance measured by satellite remote sensing can be used to evaluate optical water quality in lakes and reservoirs.

This resource contains surface reflectance data from the Landsat 5 and Landsat 7 sensors at locations throughout the Great Salt Lake, Utah Lake, and Farmington Bay in Utah, USA. Calibration data contain near-coincident samples of surface chlorophyll (from the Utah Division of Water Quality, USGS, and Jordan River-Farmington Bay Water Quality Council), while historical reflectance data contain only surface reflectance data over the historic record of 1984-2016. Reflectance data are provided for each of the visible, near infrared, and shortwave infrared bands (scaled from 0-10000). These data were downloaded via Google Earth Engine, which hosts the surface reflectance products that are produced by the USGS. Cloud Mask bands indicate data with potential cloud/haze/atmospheric interferences (any value >1).

通过卫星遥感技术测量的地表反射率，可用于评估湖泊和水库的光学水质。该资源包含美国犹他州大盐湖、犹他湖和法明顿湾等地Landsat 5和Landsat 7传感器获取的地表反射率数据。校准数据包含地表叶绿素近重合样本（来自犹他州水资源局、美国地质调查局以及约旦河-法明顿湾水质委员会），而历史反射率数据则仅包含1984-2016年历史记录中的地表反射率数据。提供的数据涵盖了可见光、近红外和短波红外波段（缩放范围为0-10000）的反射率。这些数据通过Google Earth Engine下载，该平台托管了由美国地质调查局生产的地表反射率产品。云掩膜波段表明存在潜在云层/雾霾/大气干扰的数据（任何值大于1）。
