Gallery: Aquarius Data

Scientists involved with the Aquarius/SAC-D mission have a wealth of data at their fingertips, owing in large part to the immense amount of instrumentation aboard the satellite. The main focus of the mission was to detect changes in ocean surface salinity on a global scale, as shown on monthly images produced by NASA's Goddard Space Flight Center. Scientists are also able to measure salinity variance and brightness temperature at high latitudes, which are depicted in weekly maps. (View our FAQs page for an explanation of brightness temperature.)

Global sea surface salinity map
These composite maps, showing monthly, seasonal, and annual data, are produced by Norman Kuring (NASA Goddard Space Flight Center) and are based on the latest algorithms developed by the Aquarius Calibration/Validation working group. (161 images)

Global sea surface salinity map
These composite maps show global sea surface salinity averaged by month and season.They are produced using software written by Joel Gales, John Wilding, and others at NASA Goddard Space Flight Center and are based on the latest algorithms developed by the Aquarius Calibration/Validation working group.

Global radiometer RFI map
Radio Frequency Interference (RFI) can mask the salinity signal measured by the microwave radiometers.These monthly images, produced by Paolo de Matthaeis (NASA Goddard Space Flight Center), show global monthly RFI at 1.413 GHz, the frequency of the three radiometers on board Aquarius. (45 images)

Global scatterometer RFI map
RFI can mask the salinity signal measured by the scatterometer.These monthly images, produced by Paolo de Matthaeis (NASA Goddard Space Flight Center), show global monthly RFI at 1.26 GHz, the frequency of the scatterometer on board Aquarius. (45 images)

Sea surface salinity at the north pole
These weekly maps, produced by Ludovic Brucker (NASA Goddard Space Flight Center and Universities Space Research Association) and Emmanuel Dinnat (NASA Goddard Space Flight Center and Chapman University), are made using Aquarius sea surface salinity retrievals and show sea surface salinity at latitudes higher than 50°. (392 images)

Brightness temperature at the south pole
These weekly maps, produced by Ludovic Brucker (NASA Goddard Space Flight Center and Universities Space Research Association) and Emmanuel Dinnat (NASA Goddard Space Flight Center and Chapman University), show the Aquarius (L-Band, about 1.4 GHz) brightness temperature measurements recorded at vertical polarization at latitudes higher than 50°. (392 images)

Map of sea surface salinity
These weekly gridded maps, produced by Oleg Melnichenko (International Pacific Research Center), are based on the optimum interpolation (OI) analysis of Aquarius sea surface salinity data for the North Atlantic Ocean. (195 images)

Map of sea surface density
These monthly composite maps, produced by NASA Goddard Space Flight Center's Aquarius Data Processing System, are derived from Aquarius sea surface salinity and ancillary sea surface temperature using TEOS-10 equation of state. (45 images)

Map of soil moisture
These monthly composite maps, produced by NASA Goddard Space Flight Center's Aquarius Data Processing System, are derived from L-band horizontally polarized brightness temperature observations of Aquarius. (45 images)
