The Multi-center Airborne Coherent Atmospheric Wind Sensor (MACAWS) is
an airborne, pulsed, scanning, coherent Doppler laser radar (lidar)
that remotely senses the distribution of wind velocity and aerosol
backscatter within three-dimensional volumes in the troposphere and
lower stratosphere. MACAWS, presently configured to fly on the NASA
DC-8 research aircraft, was developed jointly by the atmospheric lidar
remote sensing groups of NASA Global Hydrology and Climate Center,
NASA Marshall Space Flight Center (MSFC), NOAA Environmental
Technology Laboratory (ETL), and the Jet Propulsion Laboratory
(JPL). Nearly all of the MACAWS hardware components were developed for
previous atmospheric research programs. The re-use of these
field-tested components has resulted in considerable cost savings to
the Government. Interagency cooperation among the atmospheric lidar
remote sensing groups also ensures that research activities are both
scientifically synergistic and cost-effective. For example, the MACAWS
laser transmitter is that of the highly successful mobile ground-based
Doppler lidar ("Windvan") developed by NOAA ETL and deployed for a
number of experiments.
