title: Near infrared atmospheric absorption over a 25-knm horizontal path at sea level.
abstract: Atmospheric absorption spectra obtained over a 25-km, horizontal, sea level path in the Cape Kennedy area are presented. Six 150-cm diam carbon are searchlights positioned from 11 m to 17 m above the ground were used as sources of continuous radiation. Solar spectra obtained from sea level are traced above the corresponding horizontal path spectra for comparison. The spectral region covered is 0.68 micro to 4.86 micro and the spectral resolution varies over this region from about 0.6 x 10(-4) micro to 60 x 10(-4) micro. The amount of water vapor in the path varied from 9 to 39 precipitable cm.
