ATMOSPHERIC TEMPERATURE MEASUREMENTS USING RAMAN LIDAR

摘要

The Raman-shifted return of a lidar system has been used to make atmospheric temperature measurements. The measurements were made along a horizontal path at temperatures rang¬ing from -30 to 30° C and at ranges of about 100 meters. The temperature data were ac¬quired by recording the intensity ratio of two portions of the rotational Raman spectrum, which were simultaneously sampled from a preset range. These tests verified that the theo¬retical predictions formulated in the design of the system were adequate. Measurements were made to an accuracy of ±4 C with 1-minute temporal resolution.
