“…Thus a profile can be obtained about every 10 min. Additional details of the operation of this system have been reported by Eberhard and McNice [1986]. The problems associated with the calibration of ruby lidar systems and the methodology of data analysis have been discussed by Russell et al [1979] and by Likura et al [1987].…”

Nearly simultaneous measurements of the physical and optical properties of mixed layer and free tropospheric aerosols near Boulder, Colorado, were made on several occasions using aircraft, balloon, and ground‐based sensors. This effort (Front Range Lidar, Aircraft, and Balloon experiment (FRLAB)) was conducted with the purpose of obtaining a diverse, self‐consistent data set that could be used for testing optical model calculations based on measured physical characteristics such as apparent size distribution, composition, and shape. It was found that even with the uncertainties involved, the model predictions are in good agreement with the measurements in the visible and near infrared wavelength regions. At CO2 lidar wavelengths there is considerably more uncertainty in both the calculated and measured values; however, within the estimated errors there appears to be satisfactory agreement except for the highest free tropospheric layer studied. The results also indicate that during FRLAB the aerosol in the boundary layer and free troposphere behaved as spherical particles for optical modeling purposes. The utility of the observations for determining the extinction‐to‐backscatter ratio relevant to aerosols in the boundary layer and free troposphere is described with typical measured values being in the 20 to 30 sr range.

“…Descriptions of the instruments are given by Eberhard and McNice [1986] and by Post and Cupp [1990], respectively. These instruments transmit pulses of light in narrow beams (the ruby lidar at ,X = 0.694/,m and the CO2 lidar at 10.59/,m) and they measure the amount of light that is scattered backward toward the lidar by particulates (and also by air molecules for the ruby lidar), as a function of range.…”

Analyses of a dense set of lidar observations of the volcanic clouds from Mount Pinatubo and El Chichon, primarily over Boulder, Colorado, and at a wavelength of 10.59 μm, reveal notable similarities and differences. The importance of tropopause folding events for purging stratospheric debris into the troposphere is confirmed, as well as the role of gravitational settling to bring debris into the grasp of the folding mechanism. Seasonal influences appear more important than time after eruption in both poleward transport and in purging stratospheric material downward. We discuss the lengthening of the decay process for the Mount Pinatubo clouds by either an equatorial reservoir of debris or by eruptions of Mount Spurr. Simultaneous observations at 0.69 and 10.59 μm help monitor aerosol effective radii versus altitude with good temporal and vertical resolution.
