pyrad.proc.process_grid#

pyrad.proc.process_grid(procstatus, dscfg, radar_list=None)[source]#

Puts the radar data in a regular grid

Parameters:

  • procstatus (int) – Processing status: 0 initializing, 1 processing volume, 2 post-processing

  • dscfg (dictionary of dictionaries) –

    data set configuration. Accepted Configuration Keywords:

    datatype : string. Dataset keyword
    The data type where we want to extract the point measurement
gridconfig : dictionary. Dataset keyword
    Dictionary containing some or all of this keywords:
    xmin, xmax, ymin, ymax, zmin, zmax : floats
        minimum and maximum horizontal distance from grid origin [km]
        and minimum and maximum vertical distance from grid origin [m]
        Defaults -40, 40, -40, 40, 0., 10000.
    latmin, latmax, lonmin, lonmax : floats
        minimum and maximum latitude and longitude [deg], if specified
        xmin, xmax, ymin, ymax, latorig, lonorig will be ignored
    hres, vres : floats
        horizontal and vertical grid resolution [m]
        Defaults 1000., 500.
    latorig, lonorig, altorig : floats
        latitude and longitude of grid origin [deg] and altitude of
        grid origin [m MSL]
        Defaults the latitude, longitude and altitude of the radar
wfunc : str. Dataset keyword
    the weighting function used to combine the radar gates close to a
    grid point. Possible values BARNES, BARNES2, CRESSMAN, NEAREST
    Default NEAREST
roif_func : str. Dataset keyword
    the function used to compute the region of interest.
    Possible values: dist_beam, constant
roi : float. Dataset keyword
    the (minimum) radius of the region of interest in m. Default half
    the largest resolution
beamwidth : float. Dataset keyword
    the radar antenna beamwidth [deg]. If None that of the key
    radar_beam_width_h in attribute instrument_parameters of the radar
    object will be used. If the key or the attribute are not present
    a default 1 deg value will be used
beam_spacing : float. Dataset keyword
    the beam spacing, i.e. the ray angle resolution [deg]. If None,
    that of the attribute ray_angle_res of the radar object will be
    used. If the attribute is None a default 1 deg value will be used

  • radar_list (list of Radar objects) – Optional. list of radar objects

Returns:

  • new_dataset (dict) – dictionary containing the gridded data with fields corresponding to datatype

  • ind_rad (int) – radar index
