ER2 Geometry Utilities

load_er2_data(flight, folder='C:\\Users\\lar555\\Documents\\ACCP\\ER2\\telemetry', resample='400ms', load=True)[source]

Load the IWG1 data for a flight into a xarray.Dataset.

Parameters:

  • flight (Name of the flight used in the IWG1 file) –

  • folder (directory where the file is stored) –

  • resample (If set data will be resampled to this resolution) –

  • load (If true the resampled file will be loaded if it exists) –

Return type:

xarray.Dataset containing the IWG1 data

er2_orientation(er2, instrument_pitch_deg=0.0, instrument_yaw_deg=0.0, instrument_roll_deg=0.0)[source]

Calculate the OpticalGeometry used in Sasktran from an IWG1 point

Parameters:

  • er2 (xr.Dataset) – Containing a single time and at least attributes: [‘longitude’, ‘latitude’, ‘altitude’, ‘heading’, ‘pitch’, ‘roll’, ‘time’]

  • instrument_pitch_deg ([Optional]) – Pitch angle in degrees of the instrument relative to teh aircraft

  • instrument_yaw_deg ([Optional]) – Yaw angle in degrees of the instrument relative to teh aircraft

  • instrument_roll_deg ([Optional]) – Roll angle in degrees of the instrument relative to teh aircraft

Return type:
