AVHRR bands. Similarly, because of the spectral difference between AVHRR
bands and the corresponding MODIS/VIIRS bands, measurements from these
sensors cannot be combined together straightforwardly. The impacts of sensor
specification difference have to be determined quantitatively. With FCDR, i.e.,
time series of consistent TOA radiance data, it is feasible to construct other CDRs
