Measurements and Applications
|
Detects aerosol layers and abundance of species such as O3, NO2, OClO, BrO and NO. Consists of spectrograph and IR imager.
|
|
|
Resolution Summary
|
Spectrograph 1 km at limb, Imager 1 km in vertical
|
|
Swath Summary
|
N/A, but measures in the altitude range 5 - 100 km
|
|
Accuracy Summary
|
Depends on species. Ozone meets requirements for trend analysis
|
