Remote sensing progress overseas

Abstract

The Physics Department of the University of Newcastle has owned and operated a Daedalus (USA) airborne thermal infrared line scanner for the past 4 years. Most of the work, which has ranged over the eastern half of Australia, New Guinea and Bouganville, has utilised the 8?14 µm waveband. A 3?5 µm detector can be interchanged with the longer band width detector, but because the 3?5 band is likely to pick up some reflected solar radiation, whereas the 8?14 band gives almost pure earth radiated energy, the latter has been found more generally useful.
