v0.52.2

Breaking changes

• Flight antimeridian crossings are now detected based on individual flight segments rather than minimum and maximum longitude values. This allows for correct detection of antimeridian crossings for flights that span more than 180 degrees longitude, and may change the output of Flight.resample_and_fill for such flights.

Features

• Add experimental fill_low_alt_with_isa_temperature parameter on the AircraftPerformance base class. When set to True, aircraft performance models with Flight sources will fill points below the lowest altitude in the met["air_temperature] data with the ISA temperature. This is useful when the met data does not extend to the surface. In this case, we can still estimate fuel flow and other performance metrics through the entire climb phase. By default, this parameter is set to False.
• Add experimental fill_low_altitude_with_zero_wind parameter on the AircraftPerformance base class. When set to True, aircraft performance models will estimate the true airspeed at low altitudes by assuming the wind speed is zero.
• Add convenience Flight.plot_profile method.

Fixes

• Fix missing Fuel Flow Idle (kg/sec) value in the 1ZM001 engine in the edb-gaseous-v29b-engines.csv.
• Fix the step_threshold in Flight._altitude_interpolation. This correction is only relevant when passing in a non-default value for freq in Flight.resample_and_fill.
• Fix the VectorDataset.__eq__ method to check for the same keys. Previously, if the other dataset had a superset of the instance keys, the method may still return True.
• Fix minor bug in cocip.output_formats.radiation_time_slice_statistics in which the function previously threw an error if t_end did not directly align with the time index in the rad dataset.
• Remove the residual constraint in cocip.output_formats.contrails_to_hi_res_grid used during debugging.
• Improve detection of antimeridian crossings for flights that span more than 180 degrees longitude.

Internals

• Improve the runtime performance of Fleet.to_flight_list. For a large Fleet, this method is now 5x faster.
• Improve the runtime performance and memory footprint of Cocip._bundle_results. When running Cocip with a large Fleet source, Cocip.eval is now slightly faster and uses much less memory.
