Module Contents

class pysiral.sit.AlexandrovSeaIceDensity(*args, **kwargs)

Bases: pysiral.l2proc.procsteps.Level2ProcessorStep

A Level-2 processor step that adds sea ice density and sea ice density uncertainty to the L2 data object based on sea ice type classification

execute_procstep(l1b, l2): Mandatory method for the Level2ProcessorStep class. Will add sea ice density and uncertainty computed from the sea ice type (interpreted as multi-year ice fraction) and add output parameters to the L2 data object :param l1b: :param l2: :return: Error Status

property l2_input_vars

property l2_output_vars

property error_bit

class pysiral.sit.SeaIceFreeboard2SIT(*args, **kwargs)

Bases: pysiral.l2proc.procsteps.Level2ProcessorStep

Classical freeboard to thickness conversion assuming that the variable freeboard represent sea ice freeboard.

execute_procstep(l1b, l2): Compute sea ice thickness based on a Level-2 data object - Assuming freeboard is sea ice freeboard :param l1b: :param l2: :return:

property l2_input_vars

property l2_output_vars

property error_bit

property func: Return the function for transforming sea-ice freeboard to thickness :return:

property uncfunc: Return the function for computing sea-ice thickness uncertainty :return:

class pysiral.sit.SnowFreeboard2SIT(*args, **kwargs)

Bases: SeaIceFreeboard2SIT

Variant of the SeaIceFreeboard2SIT, but for snow freeboard to thickness conversion. This is implemented as the children to SeaIceFreeboard2SIT, with only different pointer to the correct functions

property func: Return the function for transforming sea-ice freeboard to thickness :return:

property uncfunc: Return the function for computing sea-ice thickness uncertainty :return:

class pysiral.sit.L2SeaIceDraft(*args, **kwargs)

Bases: pysiral.l2proc.procsteps.Level2ProcessorStep

A Level-2 processor step class for computing sea ice draft and its uncertainty

execute_procstep(l1b, l2): API class for the Level-2 processor. Functionality is to compute sea ice draft and its uncertainty :param l1b: Level-1 data instance :param l2: A Level-2 data instance :return: None, Level-2 object is change in place
