Thermospheric science goal
This NIR summary image maps spectrum tangent points (top) and plots quicklook spectra as a function of wavelength and longitude (bottom).

RAIDS spectral data for the MUV, NUV, and NIR spectrometers have been processed into 90-minute (approximately single orbit) quick-look summary images. These summary images map the tangent point locations for daytime (yellow) and nighttime (blue) airglow spectra on the upper panel. The lower panel plots the calibrated spectra as wavelength (y-axis), longitude (x-axis), and intensity (color). Dramatic intensity differences can be seen between daytime and nighttime observations, Other features of the data may include noise from the SAA, auroral spectra (especially in the Southern Hemisphere), serendipitous stellar signatures, and occasional scattered light from the ISS near the terminator. Usually, groups of consecutive spectra represent a limb-scan sequence in the most common operating mode.
