    • IPRC, Aquarius, Optimally Interpolated Salinity, 0.5°, Global, 7-Day, 2011-2015, v4.0, Lon0360

    Metadata Updated: June 10, 2023

    Level 4 optimally interpolated, 0.5 degree, near-global, 7 day sea surface salinity (OISSS) product for version 4.0 of the Aquarius/SAC-D dataset. OISSS is a principal investigator produced dataset developed at the International Pacific Research Center (IPRC) of the University of Hawaii at Manoa, School of Ocean and Earth Science and Technology (SOEST). The optimal interpolation (OI) mapping procedure used to create this product corrects for systematic spatial biases in Aquarius SSS data with respect to Argo near-surface salinity observations and takes into account available statistical information about the signal and noise, specific to the Aquarius instrument. The product covers the entire duration of the Aquarius/SAC-D mission: 8/26/2011 - 6/7/2015. Further details on the data processing can be found in: Melnichenko, O., P. Hacker., N. Maximenko, G. Lagerloef, and J. Potemra (2016), Optimal interpolation of Aquarius sea surface salinity, J. Geophys. Res. Oceans, 121, 602-616, doi:10.1002/2015JC011343.
