NOAA-15/16 AVHRRs exhibit minimal overall differences with other sensors.

AVHRR/1∼2 NDVI is lower than AVHRR/3 NDVI for vegetated land cover.

The NDVI difference intensifies globally and shifts northward in July.

The NDVI intercalibration equation varies with vegetation phenology.

LULC and seasonally dependent equations are recommended for NDVI intercalibration.
