Aura (Latin for breeze) was launched July 15, 2004. Aura is part of the Earth Science Projects Division.
A-SMLS (The Airborne Scanning Microwave Limb Sounder)
A-SMLS uses new submillimeter receiver and spectrometer technology to make wide-swath measurements of the composition of Earth's upper troposphere and lower stratosphere from a high altitude aircraft (e.g., NASA's WB-57 and ER-2).
CAMLS (The Compact Adaptable Microwave Limb Sounder)
CAMLS is an engineering model of a submillimeter receiver/spectrometer system that can form the core of a range of next generation space-based microwave limb sounders for atmospheric composition. CAMLS will be tested in the airborne A-SMLS instrument.
CloudSat is an experimental satellite that uses radar to study clouds and precipitation from space. CloudSat flys in orbital formation as part of the A-Train constellation of satellites (Aqua, CloudSat, CALIPSO, PARASOL, and Aura).
CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation)
The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellite provides new insight into the role that clouds and atmospheric aerosols (airborne particles) play in regulating Earth's weather, climate, and air quality.
NASA's Earth Science Program is dedicated to advancing Earth remote sensing and pioneering the scientific use of satellite measurements to improve human understanding of our home planet.
MLS - Microwave Limb Sounder
The Microwave Limb Sounder (MLS) experiments measure naturally-occurring microwave thermal emission from the limb (edge) of Earth's atmosphere to remotely sense vertical profiles of atmospheric gases, temperature, pressure, and cloud ice.
JIFRESSE is a scientific collaboration between UCLA and JPL to improve understanding and to develop future projections about global climate change.
Future generations will be in need of long-term data records of atmospheric composition to better understand the atmospheric variability and trends.
