## Introduction
The HITRAN Application Programming Interface (HAPI) [1] is a set of routines in Python which aims to provide remote access to functionality and data given by the HITRANonline. At the present time, the API can download, filter and process line-by-line transition data.
The main purpose of this API is to extend the functionality of the main site, in particular, in the calculation of spectra using several types of line shape, including the flexible HT (Hartmann-Tran) profile [2] and optionally accounting for instrumental functions. Each feature of the API is represented by a Python function taking a set of arguments which describe the parameters defining the task.
The current version is in the beta stage. All comments and suggestions are welcome: please email [[email protected]](mailto:[email protected]).
## Features
Features
Some of the prominent current features of HAPI are:
1) Downloading line-by-line data from the HITRANonline site to a local machine;
2) Filtering and processing the data in SQL-like fashion;
3) Conventional Python structures (lists, tuples, and dictionaries) for representing spectroscopic data;
4) Compatibility with a large set of third-party Python libraries to work with the data;
5) Python implementation of the HT profile [2,3,4,5] which can be used in spectral simulations. This line shape can also be reduced to a number of conventional line profiles such as Gaussian (Doppler), Lorentzian, Voigt, Rautian, Speed-dependent Voigt and speed-dependent Rautian;
6) Python implementation of the total internal partition sums algorithm, TIPS-2017[6] which is used in the calculation of the temperature dependence of HITRAN[7] transition intensities. The older software TIPS-2011[8] is also available;
7) High-resolution spectral simulation accounting for pressure, temperature and optical path length. The following spectral functions can be calculated:
a) absorption coefficient
b) absorption spectrum
c) transmittance spectrum
d) radiance spectrum
8) Spectral calculation using a number of instrumental functions to simulate experimental spectra;
9) Possibility to extend the user's functionality by adding custom line shapes, partition sums and apparatus functions.
