Advanced Mission Concepts
CAMEO
CAMEO (Composition of the Atmosphere from Mid-Earth Orbit) is a future mission concept, being developed and led by the MLS team, that uses a new orbit for composition measurements
and advanced technology in three proven instrument types: (1) ultraviolet/visible/near and shortwave infrared, (2) thermal infrared, and (3) microwave limb. The three broad-swath CAMEO
instruments provide an unprecedented combination of temporal, horizontal and vertical resolution - and global coverage - in measurements needed for air quality, climate variability and
change, ozone layer stability, weather, and the global hydrological cycle.
CAMEO's microwave instrument, the Scanning Microwave Limb Sounder (SMLS) is a major improvement of Aura MLS by having (1) simultaneous horizontal and vertical scans of the limb to provide
much-needed improvement in horizontal resolution and coverage and (2) a programmable measurement suite to allow easy cost-effective response to atmospheric events and evolving measurement
priorities. Overlapping measurements on adjacent orbits give 6 or more measurements per day everywhere over most of the globe.
The image to the right shows CAMEO's overlapping coverage on successive orbits that gives an unprecedented combination of temporal, vertical, and horizontal resolution, and global coverage needed for progress in atmospheric science and applications. Orange shows the ARIES and TROPI instrument swaths; teal blue shows the SMLS instrument swath. Yellow numbers are universal times of successive measurements over Houston (blue dot) and Beijing (red dot) for this simulated ~24-hour measurement period. Note that the illustration switches from western hemisphere to eastern hemisphere views at 00:03 UT.
