py_eddy_tracker.eddy_feature.Amplitude

class py_eddy_tracker.eddy_feature.Amplitude(contour, contour_height, data, interval, mle=1, nb_step_min=2, nb_step_to_be_mle=2)

Bases: object

Class to calculate amplitude and counts of local maxima/minima within a closed region of a sea level anomaly field.

Create amplitude object

Parameters

• contour (Contours) –

• contour_height (float) –

• data (array) –

• interval (float) –

• mle (int) – maximum number of local maxima in contour

• nb_step_min (int) – number of interval to consider like an eddy

• nb_step_to_be_mle (int) – number of interval to be consider like another maxima

Methods

all_pixels_above_h0	Check CSS11 criterion 1: The SSH values of all of the pixels are above a given SSH threshold for anticyclonic eddies.
all_pixels_below_h0	Check CSS11 criterion 1: The SSH values of all of the pixels are below a given SSH threshold for cyclonic eddies.
within_amplitude_limits	Need update
