[25-Jan-2018] The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is pleased to announce the availability of the level 3, monthly Aquarius Radio Frequency Interference (RFI) V1.0 dataset produced by NASA/GSFC. The product provides insight into the global distribution of RFI at L-band and serves as a useful adjunct to the Aquarius V5.0 end-of-mission data recently released. Maps of percentage RFI can give the user an indication of where RFI is more likely to have affected the quality of SSS retrievals over the ocean on monthly time scales. The RFI product contains monthly-averaged mapped Aquarius radiometer and scatterometer percentage RFI fields at 0.5 degree spatial resolution for the full extent of the Aquarius/SAC-D mission. RFI data variables for both ascending, descending and combined passes are included. Data files are in HDF5 format with CF-compliant metadata. Documentation on the product is available here. The dataset is discoverable via the PO.DAAC data portal and publicly accessible via both FTP and OPeNDAP. General information regarding the Aquarius/SAC-D mission is available from the mission website and also via PO.DAAC's Aquarius and salinity webpages.
