- Planetary Atmosphere Models - Models of planetary atmospheres, including 1D and 3D structure and dynamics models, chemistry, cloud models, etc.
- Planetary Interior Models - Models of planetary interiors, including mass/radius, interior thermochemistry, interior/surface evolution, etc.
- Radiative Transfer Tools - Tools used to produce simulated observations, including opacity information, spectral simulators, etc.
- Observatory/Instrument Models - Models of expected output for specific observatories or instruments, including observatory science yields, simulated data from specific instruments, etc. (occurrence rates)
- Model-Fitting Tools - Tools to fit models to data products, including light-curve fitting, spectral retrieval, etc.
- Data Reduction Tools - Tools to reduce primary data products (e.g. images) to secondary data products, including time series, photometry/spectra, etc.
- Orbital Dynamics Tools - Tools and models to determine the orbital architecture and behavior of planetary systems e.g. orbital integrators, astrometric/RV orbit determinations, transit-timing variations.

Welcome to the GSFC Exoplanet Modeling and Analysis Center (EMAC)

EMAC serves as a catalog, repository and integration platform for modeling and analysis resources focused on the study of exoplanet characteristics and environments. EMAC is a key project of the GSFC Sellers Exoplanet Environments Collaboration (SEEC).

If you make use of tools linked or hosted on EMAC, please use the following statement in your publication acknowledgements: “This research made use of the NASA Exoplanet Modeling and Analysis Center (EMAC), which is funded by the NASA Planetary Science Division’s Internal Scientist Funding Model.”

More Information on EMAC... >

EMAC is intended as a clearinghouse for the whole research community interested in exoplanets, where any software or model developer can submit their tool/model or their model output as a contribution for others to use.
EMAC provides a searchable and sortable database for available source code and data output files - both resources hosted locally by EMAC as well as existing external tools and repositories hosted elsewhere.
The EMAC team also helps develop new web interfaces for tools that can be run “on-demand” or model grids that can be interpolated for more individualized results.
If you would like to submit a new tool/model to EMAC, please visit Submit a Resource page.
If you have suggestions for tools we should recruit or improvements to the site, please visit Feedback page or email us at
Please help us determine the best tools for new web interfaces by voting on our Vote page.

The P.I. is Avi Mandell, and the Deputy P.I. is Eric Lopez; more information on EMAC staffing and organization will be posted shortly.

Planetary Spectrum Generator

Villanueva et al. Atm RT Obs

The Planetary Spectrum Generator (PSG) is an online tool for synthesizing planetary spectra (atmospheres and surfaces) for a broad range of wavelengths (100 nm to 100 mm, UV/Vis/near-IR/IR/far-IR/THz/sub-mm/Radio) from any observatory (e.g., JWST, ALMA, Keck, SOFIA).
