pyrad.proc.process_point_measurement

pyrad.proc.process_point_measurement(procstatus, dscfg, radar_list=None)

Obtains the radar data at a point location.

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,
      can be any datatype supported by pyrad and available in the data
  agg_method : string. Dataset keyword
      Which aggregation method to use to combine data that is within the
      tolerance in AziTol, EleTol and RngTol
      'nearest' : will only get nearest point to prescribed lon/lat/alt or
          ele/azi/rng
      'nearest_valid' : will only get the nearest valid point to prescribed
          lon/lat/alt or ele/azi/rng (ignore missing values)
      'average' : will average (while ignore missing values), all values
          that fall within the tolerance in AziTol, EleTol and RngTol
      'none' : will not perform any averaging and will get all values that
          fall within the tolerance in AziTol, EleTol and RngTol, each
          with its individual timestamp
      Default is 'nearest'
  latlon : boolean. Dataset keyword
      if True position is obtained from latitude, longitude information,
      otherwise position is obtained from antenna coordinates
      (range, azimuth, elevation).
  truealt : boolean. Dataset keyword
      if True the user input altitude is used to determine the point of
      interest.
      if False use the altitude at a given radar elevation ele over the
      point of interest. Default is False.
  lon : float. Dataset keyword
      the longitude [deg]. Use when latlon is True.
  lat : float. Dataset keyword
      the latitude [deg]. Use when latlon is True.
  alt : float. Dataset keyword
      altitude [m MSL]. Use when latlon is True and truealt is True
  ele : float. Dataset keyword
      radar elevation [deg]. Use when latlon is False or when latlon is
      True and truealt is False
  azi : float. Dataset keyword
      radar azimuth [deg]. Use when latlon is False
  rng : float. Dataset keyword
      range from radar [m]. Use when latlon is False
  AziTol : float. Dataset keyword
      azimuthal tolerance to determine which radar azimuth to use [deg]
  EleTol : float. Dataset keyword
      elevation tolerance to determine which radar elevation to use [deg]
  RngTol : float. Dataset keyword
      range tolerance to determine which radar bin to use [m]
  fill_value : float or None
      If not None masked values are going to be filled by this value
  

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

Returns:

• new_dataset (dict) – dictionary containing the data and metadata at the point of interest

• ind_rad (int) – radar index
