Response Linearization Look Up Tables (RLUT)

Response Linearization Look Up Tables (RLUT) are additional files that accompany Calibration Parameter Files (CPF) and contain a mapping look up table to linearize the output of the Landsat 8  and Landsat 9 OLI and TIRS detectors.

This is done to increase the range of Digital Number (DN) values for preciseness and limit the number of saturated pixels to true saturations, and on the dark end, limit it to missing data.

Non-linearity characterization uses a series of variable integration time observations of the solar diffuser and corresponding shutter observations to generate a remapping for every digital number (4096 values per detector) for every detector.

Note: RLUT files can be large and may take a while to download, please be patient.
Files are in HDF5 format. You will need to install an HDF viewer to view files.
