Module Contents

pysiral.retracker.corrections.SAMOSA_OK = True

class pysiral.retracker.corrections.ERSPulseDeblurring(*args, **kwargs)

Bases: pysiral.l2proc.procsteps.Level2ProcessorStep

A processing step applying the pulse deblurring correction of Peacock 1998 to retracked ranges.

NOTE: Should only be used for ERS-1/2 data

execute_procstep(l1b, l2)

Compute the pulse deblurring correction

Hcor = h + eps / 5. (eps < 0)

based on the classifier data transferred from the l1p (epss: epsilon in seconds). :param l1b: :param l2: :return: error_status_flag

property l2_input_vars

property l2_output_vars

property target_variables

property error_bit

property constant_slope

class pysiral.retracker.corrections.SSBCorrectionJason2(*args, **kwargs)

Bases: pysiral.l2proc.procsteps.Level2ProcessorStep

A processing step applying a sea state bias correction.

NOTE: Designed for use with SAMOSA retracker and taken from the Jason 2 mission
