Tier 1 includes scenes with the highest data quality, suitable for time-series analysis, and are represented by Level-1 Precision Terrain (L1TP) processed data. Tier 2 data, including Systematic terrain (L1GT) and Systematic (L1GS) processed scenes, do not meet Tier 1 standards. Tier 2 also includes top-of-atmosphere (TOA) reflectance data with calibration coefficients extracted from image metadata.\n"]]
