Constructors

__init__(self) → None

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

Methods

compute_abs(self, T: float, P: float, VMR: float, f: pyarts.arts.Vector) → pyarts.arts.Vector

Computes the Hitran cross-section absorption in 1/m

Parameters:

• T (Numeric) – Temperature [K]

• P (Numeric) – Pressure [Pa]

• VMR (Numeric) – VMR of species [-]

• f (Vector) – Frequency grid [Hz]

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

to_dict(self) → dict

Convert object to dict.

to_netcdf(self, arg: object, /) → object

Save XsecRecord to NetCDF file.

to_xarray(self) → object

Convert XsecRecord to xarray.DataArray().

Static Methods

from_dict(arg: dict, /) → pyarts.arts.XsecRecord

from_netcdf(arg: object, /) → object

Create an XsecRecord from a NetCDF file.

from_xarray(arg: object, /) → object

Create XsecRecord from xarray.DataArray().

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

Create variable from file

Parameters:

file (str) – A file that can be read

On Error:

Throws RuntimeError for any failure to read
