    • Bias_Uncertainty
      Bias correction parameter uncertainties are given in the data users guide.
    • Note_regarding_bias_correction
      There is some uncertainty in not only the bias correction coefficients but in the chosen parameters themselves. This release bias correction may be slightly different that of previous releases, and also somewhat different from those of previous ACOS algorithm versions. This has to do with details of the particular retrieval algorithm version and is considered normal (though not ideal).
