Seminar Abstract:

Our universe is illuminated by all kinds of light and by looking at the different colors in the electromagnetic spectrum we can investigate places near and far. The GOLD mission is a NASA mission of opportunity aboard the SES-14 satellite that views the Earth in the far ultraviolet wavelengths. It provides an unprecedented new data set for expanding our understanding of the upper atmosphere of Earth.

From these measurements we can determine the temperature and composition of the atmosphere near 160 km every half hour. These images allow us to explore the short-term “weather” and long-term “climate” of this region of our environment, a region that has critical impacts on communications and navigation, such as GPS.

This is also a region where atmospheric tides and waves from lower altitudes dissipate their energy and where the solar and geomagnetic changes can cause dramatic changes in the space environment.

Daily observations from GOLD began in October 2018, following commissioning of the instrument. In this presentation, GOLD research scientist, Katelynn Greer, will provide an overview of the GOLD mission science and examples of observations from early operations.
