Supporting documents 1-All original data used in this paper

Notes:

1. The dataset we used contains 174 transmission spectra of the sensor measured by optical spectra analyzer and their corresponding temperatures, salinities, and pressures measured by CTD. 

2. Each transmission spectrum contains 22501 wavelength points and corresponding light intensities (from line 9 to line 22509).

3. The training set (from column B to column ET) is marked in black and the testing set (from column EU to column FS) is marked in red. The testing set was randomly selected from all the data.

4. When we train the modeling, all data in training set including light intensity, temperature, salinity and pressure are launched (from line 9 to line 22513). And all sensitivity elements in sensitivity matrix are also obtained from these spectra.
