Instrument Characteristics

Observation modes

The main observation modes for OMI are the Global measurement mode, the Spatial zoom-in measurement mode and the Spectral zoom-in measurement mode. The Global Measurement mode is the default mode and samples the complete swath of 2600 km for the complete wavelength range.
The ground pixel size at nadir position in the Global mode is 13 × 24 km² (along × across track) for the UV-2 and VIS channels, and 13 × 48 km² for the UV-1 channel.
