ARB 48-inch LIDAR Data and Information

A ground-based 48-inch LIDAR system has been obtaining semi-regular measurements since May 1974. These high resolution vertical measurements have resulted in a valuable long-term record of the mid-latitude upper tropospheric and stratospheric aerosol. These data have been used in scientific studies such as in studies of volcanic eruptions and in comparisons with satellite data.
