- •
Post calibration of AVHRR data based on SeaWiFS data and pseudo-invariant targets
- •
SeaWiFS data are applied in characterizing the BRDF of the TOA reflectance over the targets.
- •
MODTRAN simulations are carried out to parameterize the spectral channel adjustment factors.
- •
BRDFs and SBAFs are applied to filtered AVHRR data to generate time series of calibration slopes.
- •
Comparisons with calibration coefficients from others exhibit validity and consistency.
