Visualization of GOLD orbiting Earth with image scanning. This version presents the singly-ionized oxygen density from the IRI model.

A basic view of the orbit for GOLD (Global-scale Observations of the Limb and Disk). This mission will conduct measurements of ionospheric composition and ionization better understand the connection between space weather and its terrestrial impacts.

In this visualization, we present GOLD in geostationary orbit around Earth. The colors over Earth represent model data from the IRI (International Reference Ionosphere) model of the density of the singly-ionized oxygen atom at an altitude of 350 kilometers. Red represents high density. The ion density is enhanced above and below the geomagnetic equator (not perfectly aligned with the geographic equator) on the dayside due to the ionizing effects of solar ultraviolet radiation combined with the effects of high-altitude winds and the geomagnetic field.

In the latter half of the visualization, the viewing fields of the GOLD instrument are displayed. GOLD has an imaging spectrometer (green) that periodically scans the disk of Earth with additional higher-resolution scans of the dayside limb.
