Abstract
A series of infrared contrast measurements of heated buildings against snow background was carried out at DREV under a variety of winter weather conditions to obtain an indication of the usefulness of this type of equipment during inclement weather in the Arctic. Images were obtained on an 8-13 m AGA Thermovision which was calibrated using a portable AGA Source and a Barnes PRT-5 radiometer. In ordinary snowfall the infrared was no better than, and sometimes inferior to, visual performance. However, there was some indication of an advantage for the infrared in very fine blowing or falling snow as well as a distinct advantage in some fog conditions.
