Abstract:

Simultaneous observations of the lower atmosphere with lidar laser radar and microwave radar are summarized. The observations are restricted in space to the location of Stanford Research Institute, Menlo Park, California, and in time to June, August, and September 1966. Lidar echoes from the clear lower atmosphere are compared with the temperature and humidity data from the rawinsonde ascents made at Oakland, California. During clear skies, no radar or lidar echoes were observed above 20.00 m. Below this level the atmospheric structure that was analyzed from the lidar data showed a diurnal variation similar to that of the thermal stability of the atmosphere. Other time- dependent variations that were evident in the data are believed to be related to short period changes in the height of the top of the marine layer. No specific relationship was found between the lidar data and the rawinsonde data from Oakland. Radar echoes observed in the clear lower atmosphere were classified as meteorological angles.
