Global Emission Spectra

The GlobES application allows to ingest climatological data from a variety of General Circulation Models (GCM) and to accurately synthesize planetary spectra. The 3D and temporal atmospheric data is aggregated and mapped into a 2D projected observationally grid that is fed to the Planetary Spectrum Generator (PSG). More information here.

Parameters of the spectroscopic 3D synthesis

The parameters of the (exo)planet and its host star are as defined in the Target and Geometry section of PSG. This also includes the observational conditions (e.g., distance to the object, inclination, phase), while in this section, the user can also quickly define observational mode (i.e., transit, direct imaging and phase). However, it is important that the user verifies the parameters in the Target and Geometry section. The atmosphere and surface information will be as defined in the Atmosphere and Surface section, while the algorithm will use the 3D atmospheric data defined in this section to establish the vertical profiles at each location.
