Data Link:

  • Level1a

    The information in Level 1a data is the raw data down link from satellite recorded in netCDF format.

  • Level1b

    TRITON_TTTTTT_YYYYMMDDHHNNSS_CorDDM_vV.V_nc (File Description)

    The Level 1b CorDDM data is recorded in netCDF format and information in Level 1b CorDDM data is the same to level 1a and has been corrected the time shift occurs in receiver software. In Level 1b CorDDM data also record the calibrated DDM which remove the effect from the antenna and receiver.

  • TRITON_TTTTTT_YYYYMMDDHHNNSS_metadata_vV.V_nc (File Description)

    The Level 1b metadata is recorded in netCDF format. The information in Level 1b metadata is the intermediate data calculated from Level 1b CorDDM data for further application. The main information in Level 1b metadata are the code phase and Doppler frequency of specular point, effective scattering area, and normalized bistatic radar cross section etc.

  • Level2

    TRITON_TTTTTT_YYYYMMDDHHNNSS_roughness_windspeed_vV.V_nc (File Description)

    The retrieved ocean surface wind speed (U10 < 20m/s) and roughness (mean square slope and significant height) are recorded in Level 2 data.
