ABoVE: Lake Growing Season Green Surface Reflectance Trends, AK and Canada, 1984-2019 : Arctic-Boreal Vulnerability Experiment (ABoVE)
This dataset provides an annual time series of Landsat green surface reflectance and the derived annual trend during the growing season (June and July) for 472,890 lakes across the ABoVE Extended Study Domain from 1984 to 2019. The reflectance data are from Landsat-5, Landsat-7, and Landsat-8 sensor...
