| 内容記述 | Two focused coherent, continuous wave (CW) lidars have been developed by the Marshall Space Flight Center (MSFC) for airborne and ground-based measurement of aerosol backscatter coefficients. The first of these instruments uses a mixture of CO2 and other gases, and measures backscatter at 10.6 m. The second lidar uses an isotope of carbon dioxide, which enables lasing at 9.1 m. The 10.6 m backscatter measurement serves as a reference to allow variations in backscatter due to aerosol concentration to be distinguished from variations due to spectral variability. The 10.6 m lidar has been used in airborne field programs since 1981. Development of the 9.1 m lidar was completed in early 1989. Recently, both lidars were flown on the NASA/Ames Research Center DC-8 research aircraft in the remote Pacific Basin as part of the NASA GLObal Backscatter Experiment (GLOBE) survey missions. The GLOBE program, of which the survey missions are the centerpieces, supports design and simulation studies for NASA's prospective Laser Atmospheric Wind Sounder (LAWS). |
