Tier 1 scenes are of the highest quality, suitable for time-series analysis, and include Level-1 Precision Terrain (L1TP) processed data. Tier 2 contains scenes that didn't meet Tier 1 standards, including Systematic terrain (L1GT) and Systematic (L1GS) processed scenes. Both tiers represent scaled, calibrated at-sensor radiance and utilize DN values. Both tiers are identified by the same tags.\n"]]
