  • 0.1 (2018-12-05):

    RA: Preliminary Data.  For in-field use only.

  • 0.2 (2018-12-20):

    RC: Preliminary Data.

  • 0.3 (2018-12-21):

    RD: Preliminary Data.

  • 1.0 (2019-05-14):

    R0: Time lag Adjusted wrt to PCASP. Values from SDI are converted to STP (0c, 1 atm). CVI values are absorption measured during CVI inlet. Denuded absorption and scattering data need to be used with caution. Discussion with PI or DM recommended.
