v0.42.2

This is a re-release of v0.42.1, which didn't make it to PyPI. The release notes from v0.42.1 are copied below.

Features

  • Add new HistogramMatchingWithEckel experimental humidity scaling model. This is still a work in progress.
  • Add new Flight.fit_altitude method which uses piecewise linear fitting to smooth a flight profile.
  • Add new pycontrails.core.flightplan module for parsing ATC flight plans between string and dictionary representations.
  • Add new airports and flightplan examples.

Breaking changes

  • No longer attach empty fields "sdr", "rsr", "olr", "rf_sw", "rf_lw", "rf_net" onto the source parameter in Cocip.eval when the flight doesn't generate any persistent contrails.
  • Remove params humidity_scaling, rhi_adj_uncertainty, and rhi_boost_exponent_uncertainty from CocipUncertaintyParams.
  • Change the default value for parallel from True to False in xr.open_mfdataset. This can be overridden by setting the xr_kwargs parameter in ERA5.open_metdataset.

Fixes

  • Fix a unit test (test_dtypes.py::test_issr_sac_grid_output) that occasionally hangs. There may be another test in test_ecmwf.py that suffers from the same issue.
  • Fix issue encountered in Cocip.eval when concatenating contrails with inconsistent values for _out_of_bounds. This is only relevant when running the model with the experimental parameter interpolation_use_indices=True.
  • Add a Fleet.max_distance_gap property. The previous property on the Flight class was not applicable to Fleet instances.
  • Fix warning in Flight class to correctly suggest adding kwarg drop_duplicated_times.
  • Fix an issue in the VectorDataset constructor with a data parameter of type pd.DataFrame. Previously, time data was rewritten to the underlying DataFrame. This could cause copy-on-write issues if the DataFrame was a view of another DataFrame. This is now avoided.

Internals

  • When possible, replace type hints np.ndarray -> np.typing.NDArray[np.float_] in the cocip, cocip_params, cocip_uncertainty, radiative_forcing, and wake_vortex modules.
  • Slight performance enhancements in the radiative_forcing module.
  • Change the default value of u_wind and v_wind from None to 0 in Flight.segment_true_airspeed. This makes more sense semantically.
