PO.DAAC has made available both Level 2 and Level 3 data for version V1.2DR of the Aquarius/SAC-D data set. The differences between V1.2DR and V1.2 result from the change of correction technique for radiometer calibration drift. For V1.2DR, the brightness temperature corrections are computed using the noise-diode deflection ratios derived from the instrument data alone, and the ancillary data were only used to train the coefficients in the deflection-ratio based correction model initially.
