Title: PSG: An online tool for synthesizing spectra of planets, exoplanets and small bodies from any telescope/mission
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. The tool includes a 1) 3D (three-dimensional) orbital calculator for any solar system body and all confirmed exoplanets; 2) The tool ingests billions of spectral lines and optical constants from almost 1,000 chemical species and ices/solids; 3) It contains realistic instrument/telescope models and noise/SNR calculators for coronographs, interferometers (e.g. ALMA), space orbiters, etc; 4) The code calculates terrestrial transmittances for a broad range of conditions (altitude and water vapor columns, SOFIA, balloons). A short introduction and a live-demo will be given.
