These 'Fraunhofer' lines are due to the absorption of light of specific frequencies by the gases in the upper atmosphere of the sun. \(1\). Line spectra are produced when electrons move from one ...

basic research is carried out with the goal of developing procedures and methodologies for highly precise derivation of known atmospheric state variables as well as extending their application to ...

These studies indicate that as the molecular complexity of Criegee intermediates increases, their absorption spectra shift, which may enhance their removal from the atmosphere through solar ...

Differential Absorption Lidar (DIAL) is an advanced remote sensing technology used to measure atmospheric gases, particularly greenhouse gases like carbon dioxide (CO2) and methane (CH4).

So we know the exoplanet is there, and have a good idea of its size and mass, but since it doesn't transit its star we can't observe its atmospheric absorption spectrum. But a new study posted to ...

Since many of these gases are trace gases with extremely weak absorption/emission features in spectra ... when they might not be detected in the original spectral data. NASA’s Planetary Spectrum ...
