Measurements and Applications
Measures natural and human-produced gases and aerosols in the atmosphere, including those that react in sunlight to form polluting low-level ozone.

[Best Resolution: 7000m]
Swath
typically uses 2D data array with 1-D north to south in space (7 km wide) and 1D for (oversampled) spectral intervals/bins. The spatial domain is mechanically scanned for east to west to cover a continental domain (either north or south America).
Accuracy
ozone precision: 1.3 x 10^16 cm^(-2); NO2 precision: 5 x 10^14 cm^(-2)
