glidertools.processing.calc_par

glidertools.processing.calc_par(par_raw, dives, depth, time, scale_factor_wet_uEm2s, sensor_output_mV, curve_max_depth=80, verbose=True)

Calculates the theoretical PAR based on an exponential curve fit.

The processing steps are:

  1. par_scaling (factory cal sheet scaling)

  2. par_dark_count (correct deep par values to 0 using 5th %)

  3. par_fill_surface (return the theoretical curve of par based exponential fit)

Parameters:

  • data (All inputs must be ungridded np.ndarray or pd.Series)

  • par_raw (array, dtype=float, shape=[n, ]) – raw PAR

  • dives (array, dtype=float, shape=[n, ]) – the dive count (round is down dives, 0.5 up dives)

  • depth (array, dtype=float, shape=[n, ]) – in metres

  • time (array, dtype=float, shape=[n, ]) – as a np.datetime64 array

Returns:

par_filled – PAR with filled surface values.

Return type:

array, dtype=float, shape=[n, ]
