ctdcal.equations_sbe.sbe4(freq, t, p, coefs, decimals=4)[source]

SBE equation for converting SBE4 frequency to conductivity. This conversion is valid for both SBE4C (profiling) and SBE4M (mooring). SensorID: 3

Parameters

  • freq (array-like) – Raw frequency (Hz)

  • t (array-like) – Converted temperature (ITS-90 degrees C)

  • p (array-like) – Converted pressure (dbar)

  • coefs (dict) – Dictionary of calibration coefficients (G, H, I, J, CPcor, CTcor)

Returns

c_mS_cm – Converted conductivity (mS/cm)

Return type

array-like
