Popis: A CUBI, a simple geometric metal test-object, is placed in an outdoor environment to monitor the infrared signature. The (daily) temperature evolution of the individual facets is monitored as function of environmental parameters, such as solar irradiance and ambient temperature. This provides insight in the parameters that have the strongest effects on the thermal signature of the CUBI. The CUBI is also imaged by infrared cameras and these recordings are used to estimate the temperature of the CUBI. The recorded images are also used to provide insight in the amount of air turbulence generated by the radiance of the hot CUBI facets. The amount of turbulence is compared with the ambient turbulence as calculated by standard bulk theories.
