Welcome to the documentation for Astroclimes!

Astroclimes is a synthetic telluric transmission algorithm that can be used to measure the abundance of greenhouse gases in the Earth’s atmosphere using astronomical observations or to remove telluric lines from stellar spectra.

Please cite Fetzner Keniger et al. (2025) and/or Fetzner Keniger et al. (2026) if you use Astroclimes in your research.

For instructions on how to install and use Astroclimes, check out the Getting started with Astroclimes section and references therein.
