GUVI measures FUV airglow in five spectral 
bands: HI(121.6nm), OI(130.4nm), 
OI(135.6nm), LBHS(141-152.8nm), and  
LBHL(167.2-181.2nm). The cross-track 
scanning spectrograph images a 
ground swath of 3000 km width 
providing a nearly contiguous 
global coverage duringone day 
(15 orbits).
 
The L1CDisk (Level 1C disk, V03) data 
provide the calibrated, geolocated,
and rectified intensities for the 5
wavelengths bands. 
DISPLAY OPTIONS:    
(1) Mapped images of the (lin or log) 
intensities by orbit using a transverse
Mercator projection.
(2) Mapped images of the (lin or log) 
intensities using a polar projection
of the North and South pole areas.
  Generating thumbnails for (1) or (2) 
  for one day takes about 1 minute.
(3) Movies of plot types (1),(2):
There are 15 orbits/frames per day,
max is 2 days, i.e. 30  frames. 
(4) Images of intensitiesas scanned
along the orbit.
(5) Line plots of intensities
at selected across-track positions.

Description of
CDAWeb TIMED/GUVI L1C_disk
Note: THE L1C FILES CURRENTLY AVAILABLE ARE BEING EVALUATED; It looks like the L1C LBH1 and LBH2 colors have too much background subtracted.
