June 1999 measurement of low-altitude infrared transmission approved for public release; distribution is unlimited. iiiThis report reviews the influence of these mechanisms on infrared transmission at low altitudes and then describes the design, operation, and limitations of a transmissometer suitable for measuring broadband atmospheric transmission and scintillation in coastal regions....
Comparison of modtran simulations and transmission measurements by path-integrated and in-situ techniques over a rural site in northwestern germany... Direct transmission measurements were made by a 7-wavelength transmissometer....
Transmissometer versus sun photometer measurements of the aerosol optical properties... The first is a standard 5-wavelength hand-held sun photometer yielding the vertical column extinction, the second a 7-wavelength transmissometer developed at TNO....
Comparison of lidar and transmissometer measurements through cloudsA lidar-transmissometer intercomparison was made during an international experiment held in the German Alps to characterize the vertical structure of aerosols and clouds....
