Landsat MSS products with inaccurate brightness values to be reprocessed
The USGS/NASA Calibration/Validation Team has recently discovered that over 44,000 Landsat 2 and Landsat 3 Multispectral Sensor (MSS) Level-1 products were processed in 2020 with a calibration parameter file (CPF) that contained incorrect gain/offset values.
The incorrect values cause a slightly noticeable difference in the brightness (known as the digital number - DN) values of the pixels within an affected product—Band 4 and Band 5, specifically. The band data display higher or lower DN values than they should, resulting from the coefficient applied during Level-1 processing.
A solution to rectify this issue and apply the correct CPF to the affected products has been identified. After Landsat systems are updated with the solution, Level-1 products will be reprocessed. An new headline will be posted when the products are reprocessed.
Please visit the Landsat Collection 2 Known Issues webpage to access a list of the affected scenes.
