nasapsg/psg repository overview

The Planetary Spectrum Generator (PSG) is an online tool for synthesizing planetary spectra (atmospheres and surfaces) for a broad range of wavelengths (0.1 μm to 100 mm, UV/Vis/near-IR/IR/far-IR/THz/sub-mm/Radio) from any observatory (e.g., JWST, ALMA, Keck, SOFIA), any orbiter (e.g., MRO, ExoMars, Cassini, New Horizons), or any lander (e.g., MSL). This is achieved by combining several state-of-the-art radiative transfer models, spectroscopic databases and planetary databases (i.e., climatological and orbital).

To visit the local site of PSG, open your browser and go to http://localhost:3000⁠, while to run the local version of the Application-Program-Interface (API), enter the following command:

curl --data-urlencode [email protected]⁠ http://localhost:3000/api.php⁠

By default, the personal suite of PSG comes with the PROGRAMS and BASE packages, yet the user can install many additional packages, expanding the capabilities of the local version. Specifically, the correlated-k tables for low/moderate spectral resolutions can be quite heavy, and should be installed only when strictly necessary. This site also keeps track of any updates of these packages with respect to the current PSG suite, and it will inform you if you are required to update the packages.
