HAPI isa programming interface for the main data-searching capabilities of the new HI-TRANonline web service (www.hitran.org). It provides the possibility to query spec-troscopic data from the HITRAN [2] database in a flexible manner using either func-tions or query language. Some of the prominent current features of HAPI are: a)Downloading line-by-line data from HITRANonline b) Filtering and processing thedata in SQL-like fashion c) Using conventional Python data structures for represent-ing spectroscopic data d) Possibility to use a large set of third-party Python librariese) Python implementation of the Hartmann-Tran line profile [3] f) Python imple-mentation of total internal partition sums (TIPS-2011 [4]) for spectra simulations g)High-resolution spectra calculation accounting for pressure, temperature and opticalpath length h) Providing instrumental functions to simulate experimental spectra i)Possibility to extend the functionality by user’s custom code.Currently the API is a module written in Python and designed to deal with datain multiple formats such as ASCII, CSV, HDF5 and XSAMS.This work has been supported by NASAAura Science TeamGrant NNX14AI55Gand NASA Planetary Atmospheres Grant NNX13AI59G.References[1] www.hitran.org/hapi[2] L.
