Paper Abstract

From February to May 1977, extensive atmospheric transmission measurements were carried out over a 5.08 km, over-water path at Cape Canaveral Air Force Station using NRL's Infrared Mobil Optical Radiation Laboratory. This paper will report transmission measurements of 80 CO2 laser lines for three measurement periods. These periods were typified by high visibilities, (> 20 km), and 7.4, 15.7, and 18.4 torr atmospheric water vapor contents, respectively. The set of laser lines include the following transitions: 00°1 - 10°0 P4 to P44 and R4 to R42 00°1 - 02°0 P4 to P42 and R4 to R40 The Hitran calculations of atmospheric extinction were made using a computer code adapted by NRL for our DEC 11/40. The December 1975 AFCRL line compilation was augmented by a current H2O continuum model. A comparison points out possible problems with some H2O absorption lines as well as the shape of the water continuum absorption profile.
