Much work is being undertaken on the characterisation of the evaporation duct above warm tropical oceans in Australia. This work is being carried out jointly by the University of Canberra's Radio Systems Research Group (RSRG), The Defence Science and Technology Organisation (DSTO) and James Cook University.

Previous work has established the average height of the duct and diurnal changes in the duct in various climatic conditions and seasons. Propagation at 10.6 GHz over a 20-km path has also been measured. This paper describes an experiment over a very long path of 72.2 km using a very low transmit antenna height (4 metres) and a receiving array ranging from 3.6m AMSL to 11.7m AMSL.

Analysis of received signal strength along with weather conditions is presented along with an analysis of anomalous received signal strengths and suggestions for causal effects. This data is compared to the AREPS model produced by the US Navy SPAWAR Centre and conclusions are drawn for this path and for further work.
