SEE

The Solar EUV Experiment (SEE) is one of the four scientific instruments aboard the TIMED spacecraft. The SEE instrument is determining the irradiance of the highly variable solar extreme ultraviolet (EUV) radiation, one of the major energy sources for the upper atmosphere. SEE measurements are fundamental for the TIMED mission’s investigation of the energetics in the tenuous but highly variable layers of the atmosphere above 60 km.
