We report on propagation measurements performed during the MINOTAUROS (Maritime INvestigations On Targets and Atmosphere Under Reduction of Optical Signatures) experiment on Crete, Greece, in late summer of 2016. The field trial has been organized by NATO STO Task Group SET-211 on Naval Platform Protection in the EO/IR Domain with strong support of the Hellenic Navy. Besides meteorological measurements, the experiment included measurements of turbulence using a boundary layer scintillometer on a slant path (d = 8 km) across the entry of Souda Bay (Crete). These are compared to values obtained by a 3D sonic anemometer, which was deployed at one end of the propagation path. Refraction effects have been measured using a 17.5 km path from Drapanos to Gerani. Two meteorological buoys along the path were used to gather information about the atmospheric conditions. An overview and a first analysis of the results are presented. The refraction measurements are compared to simulations using MORTICIA (Model of Range and Transmission in Coastal Inland Atmospheres), a new software tool currently under development in a collaboration of Fraunhofer IOSB and TNO.
