Atmospheric Remote Aerosol Measurements |
||
|
Both aerosol measurements and measurement techniques are studied experimentally. Stratospheric aerosols have been monitored since 1974 at Mauna Loa Observatory by the Lidar (laser radar) method. El Chichon and Mount Pinatubo, the last two major eruptions having appreciable climate effects, were both observed. The current lidar measures aerosol scattering at two wavelengths as well as tropospheric water vapor, and stratospheric and mesospheric temperature. The lidar is part of the Network for the Detection of Stratospheric Change. A new technique is being developed for measuring boundary layer aerosols by imaging the laser beam from about 200 meters away with a wide angle lens and CCD camera. The technique, called CLidar, has the advantage over the standard lidar method of very high altitude resolution all the way to the ground. The method is also relatively simple and inexpensive when compared to the standard method. |
