September 28, 2012 - Landsat releases quarterly Calibration Parameter File

Once a quarter, the radiometry experts on the Landsat team craft a new Calibration Parameter File (CPF), which is then incorporated into processing new and archived data.

For Landsat 5 TM products created on or after 1 October, the update will improve radiometric accuracy and will significantly reduce or eliminate residual banding and striping. See the Calibration Notices webpage for more information.
