AmdarTurbulenceData#

class rojak.core.data.AmdarTurbulenceData(data_frame, grid)[source]#

Abstract container for AMDAR turbulence observations, spatially bucketed onto a grid

Quality control (deduplication, minimum altitude, and manoeuvre filtering) is applied to the data on construction, see __apply_quality_control().

Parameters:

  • data_frame (dd.DataFrame)

  • grid (dgpd.GeoDataFrame)

__init__(data_frame, grid)[source]#
Parameters:

  • data_frame (dd.DataFrame) – AMDAR observations, spatially joined onto grid (see AmdarDataRepository.to_amdar_turbulence_data()). Must contain "datetime", "index_right", "level", and "geometry" columns.

  • grid (dgpd.GeoDataFrame) – Grid data_frame was spatially bucketed onto

Raises:

AssertionError – If data_frame is missing any required column

Return type:

None
