Table 7 lists the 48-inch lidar measurements at 0.69 µm taken with ruby laser in Hampton, Virginia (37.1°N, 76.3°W). An aerosol layer peak was located at 19.3-25.3 km during early October; lidar backscatter ratios were consistent at 1.11-1.16 (table 7).

Table 7. Lidar data from Virginia, USA, showing altitudes of aerosol layers. Backscattering ratios are for the ruby wavelength of 0.69 µm. Integrated values show total backscatter, expressed in steradians-1, integrated over 300-m intervals from the tropopause to 30 km.
