Abstract:

An experiment was conducted to determine whether ducting phenomena gradients in refractivity occur close to the ocean surface at infrared wavelengths. A CO2 laser beam 10.6 microns was transmitted and received over an 8.5 km path in San Diego Bay. For the cases investigated sea warmer than the air, the results of the study indicate that for air temperature gradients less than 1 Cmeter, the distance to the infrared horizon was only 60 of the normal geometrical horizon.
