Abstract:
|
The Global-scale Observations of the Limb and Disk (GOLD) FUV imager is designed to make full-disk observations of the Earth’s thermosphere and ionosphere from geo-synchronous orbit on a commercial communications satellite. Four scientific questions are addressed by the GOLD mission. Here we concentrate of the first of these questions, which relates to the response, in the low and middle latitudes, of neutral composition and temperature to geomagnetic forcing. For the first time GOLD will provide simultaneous measurements of temperature and composition changes over the disk, permitting an unambiguous understanding of the coincident storm time evolution of these fields both in relation to their longitudinal and local time variations. In addition, the real-time capability to download GOLD data with a latency of less than 15 minutes will provide the opportunity to use assimilative techniques to improve nowcast and forecast models of the low Earth orbital environment. |
