Some scenes, especially those from previous satellites fall short of the 12 meter RMSE goal, and are categorized into tier 2. The aim is to produce seamless products with normalized parameters, which include atmospheric . Landsat 4 . Landsat Collection 2 marks the second major reprocessing effort on the Landsat archive by the USGS that results in several data product improvements that harness recent advancements in data processing, algorithm development, and data access and distribution capabilities. The purpose of this handbook is to provide a basic understanding and associated reference material for the L8 Observatory and its science data products. Collection 2 includes Landsat Level-1 data for all sensors since 1972, as well as global Level-2 surface reflectance and surface temperature scene-based products from 1982 to present (excluding Landsat 1-5 Multispectral Scanner (MSS)) within defined constraints.

The recorded spectral wavelengths are coastal/aerosol, green, blue, red, Near Infrared (NIR), Shortwave Infrared (SWIR) 1, SWIR 2, pan, cirrus, Thermal Infrared (TIR) 1, and TIR 2 as band 1 to band 11 respectively. However, the thermal bands require additional processing before the scene is placed into the final tier. The cross-track scanning was accomplished by an oscillating mirror; six lines were scanned simultaneously in each of the four spectral bands for each mirror sweep. The forward motion of the satellite provided the along-track scan .
