A 2.1 &mu;m &ldquo;eye-safe wavelength&rdquo;, 25mJ/pulse (A/O Q-switching), 90ns/pulse Ho lidar systemhas been developed to measure atmospheric extinction coefficients, &alpha;, and backscatter coefficients, &beta;. Range esolved values of &alpha; and &beta; were obtained at ranges covering up to 1.5km forsevera 124 hour periods. The average values of &alpha; were on the order of 10<SUP>-3</SUP> to 10<SUP>-4</SUP>m<SUP>-1</SUP> and &beta; values were estimated on the order of 10<SUP>-5</SUP> to 10<SUP>-6</SUP> m<SUP>-1</SUP> sr<SUP>-1</SUP>. The variation of &beta; as a function ofrange was small during the period from night to early morning, but increased significantly duringthe later daytime hours. The values of &beta; were somewhat higher from midnight to earlymorning than just after sunrise and then gradually decreased. &beta; values exhibited good correlation with the atmospheric humidity. From these observations it was confirmed that thelidar system developed is a powerful apparatus for remote sensing of the atmosphere.
