Worldwide Maritime Infrared Atmospheric Transmittance Data
Abstract
This report provides extinction coefficients which model infrared atmospheric transmittance. A pair of coefficients define a decaying exponential from a two-parameter curve fit to transmittance values for 10 and 20-km path lengths. Each location has approximately 700 individual sets of weather observations with a corresponding set of extinction coefficients. These coefficients are calculated from actual maritime meteorological conditions and the LOWTRAN 7 atmospheric transmittance model. There is a total of 9,833 sets of parameters worldwide. The meteorological conditions were measured over a 10-year period in the 1960s and early 1970s and are evenly distributed throughout the seasons. The weather parameters used as inputs to the LOWTRAN 7 model are relative humidity, air temperature and pressure, current and 24-hr average wind speed, and a calculated rain rate.
