Dear all,

I’m happy to announce the release of [HITRAN.jl](https://github.com/TacHawkes/HITRAN.jl), a package meant for calculating high-resolution molecular absorption spectra based on the HITRAN database.

The package takes a similar approach as the official HITRAN Application Programming Interface (HAPI) available for Python. This package provides a native Julia implementation of lineshape functions (Hartmann-Tran is the default) and a local database management (using SQLite.jl) by fetching subsets of the HITRANOnline database.

You can find out a lot more about the features and how to use it [here](https://tachawkes.github.io/HITRAN.jl/dev/).

Let me know if you find it useful, have a feature request or found a bug.
