AVHRR Prelaunch Calibration Version III
Status • Version I in CPIDS for NOAA-15/16/17, and presumably earlier satellites • Version II in CPIDS NOAA-18 (Jan 2003) • Version III in CPIDS for METOP-A (April 2006) • Did not intend to change for earlier satellites (out of respect to historical “pre-launch cal coeff”) • Now that they have been changed for other reasons, recommend to change to Version III • Another option (Cao): Change on web, not on 1B
