Data assimilation

Assimilation of Hyperspectral Infrared Observations with Optimal Spectral Sampling

  Current data assimilation (DA) systems use only a small fraction of the thousands of channels from hyperspectral infrared sounding instruments, including IASI, AIRS, and CrIS. An alternative that retains nearly the full hyperspectral information content at greatly reduced computation cost, while filtering instrument noise, is to assimilate the optimal spectral sampling (OSS) node radiances.
