CIARecord

class pyarts.arts.CIARecord(*args, **kwargs)

Contains information to compute collision induced absorption for a pair of species

Holds an the record data in a gridded field with grids of temperature and frequency in units of m^5 molec^(-2)

Constructors

__init__(self) → None

__init__(self, arg: pyarts.arts.CIARecord) → None

__init__(self, arg0: pyarts.arts.ArrayOfGriddedField2, arg1: pyarts.arts.SpeciesEnum, arg2: pyarts.arts.SpeciesEnum, /) → None

Methods

compute_abs(self, T: float, P: float, X0: float, X1: float, f: pyarts.arts.Vector, T_extrapolfac: float = 0.0, robust: int = 1) → pyarts.arts.Vector

Computes the collision-induced absorption in 1/m

Parameters:

• T (Numeric) – Temperature [K]

• P (Numeric) – Pressure [Pa]

• X0 (Numeric) – VMR of species 1 [-]

• X1 (Numeric) – VMR of species 2 [-]

• f (Vector) – Frequency grid [Hz]

• T_extrapolfac (Numeric, optional) – Extrapolation in temperature. The default is 0

• robust (Index, optional) – Returns NaN instead of throwing if it evaluates true. The default is 1

Returns:

abs – Absorption profile [1/m]

Return type:

Vector

readxml(self, file: str) → None

Read variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read

savexml(self, file: str, type: str = 'ascii', clobber: bool = True) → None

Saves variable to file

Parameters:

• file (str) – The path to which the file is written. Note that several of the options might modify the name or write more files

• type (str) – Type of file to save. See FileType for options.

• clobber (bool) – Overwrite existing files or add new file with modified name?

On Error:

Throws RuntimeError for any failure to save

Static Methods

fromxml(file: str) → pyarts.arts.CIARecord

Create variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read
