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).
