pysiral.ers.l1_adapter.__author__ = 'Stefan Hendricks'

class pysiral.ers.l1_adapter.ERSReaperSGDR(cfg, raise_on_error=False)

Bases: pysiral.l1preproc.Level1PInputHandlerBase

Converts a Envisat SGDR object into a L1bData object

timer = None

l1 = None

filepath = None

get_l1(filepath, *args, **kwargs): Read the Envisat SGDR file and transfers its content to a Level1Data instance :param filepath: The full file path to the netCDF file :return: The parsed (or empty) Level-1 data container

_read_sgdr(): Read the L1b file and create a ERS native L1b object

_set_input_file_metadata(): Extract essential metadata information from SGDR file

_set_l1_data_groups()

_transfer_timeorbit() → None

Extracts the time/orbit data group from the SGDR data and set the l1 timeorbit data group

Raises:: None –
Returns:: None

_transfer_waveform_collection(): Transfers the waveform data (power & range for each range bin)

_transfer_range_corrections()

Transfer range correction data from the SGDR netCDF to the l1bdata object. The parameter are defined in config/mission_def.yaml for ers1/ers2 -> ersX.settings.sgdr_range_correction_targets

For a description of the parameter see section 3.10 in the REAPER handbook

_transfer_classifiers(): Transfer classifier parameter from the SGDR netCDF to the l1bdata object. Most parameter are defined in config/mission_def.yaml for ers1/ers2 -> ersX.settings.sgdr_range_correction_targets

_transfer_surface_type_data()

property empty: Default return object, if nodata should be returned :return: Representation of an empty object (None)
