sasktran2.database.MieDatabase

class sasktran2.database.MieDatabase(psize_distribution: ParticleSizeDistribution, refractive_index: RefractiveIndex, wavelengths_nm: array, db_root: Path | None = None, backend: str = 'sasktran2_cpp', max_legendre_moments: int = 64, num_size_quadrature: int = 1000, num_threads=1, **kwargs)

Bases: CachedDatabase, OpticalDatabaseGenericScattererRust

A MieDatabase is a database that caches Mie scattering data on the local file system. The root directly can optionally be specified, otherwise the default folder is used.

Parameters:

• psize_distribution (ParticleSizeDistribution) – The particle size distribution

• refractive_index (RefractiveIndex) – The refractive index

• wavelengths_nm (np.array) – The wavelengths to calculate the Mie parameters at

• db_root (Path, optional) – The root directory to store the database, by default None

• backend (str, optional) – The backend to use, by default “sasktran2_cpp”. Currently supported options are [“sasktran_legacy”, “sasktran2”, “sasktran2_cpp”]. “sasktran_legacy” requires the module sasktran to be installed.

• num_threads (int, optional) – The number of threads to use for the calculation, by default 1. Only current works in the sasktran2_cpp backend

• kwargs – Additional arguments to pass to the particle size distribution, these should match the psize_distribution.args() method
