[QUOTE="sophiecentaur, post: 6247463, member: 199289"] A thermal imager looks at the em radiation from a source. The air in between will have some input but the image would be dominated by the target and the actual [I]background. [/I]After a day of serious cooking by the Sun, some of the background surfaces would be 'warm to the touch' (cooling rapidly by radiation into space) but there could be low contrast in an image of a body in front of those surfaces. The shape of a target would also help to recognise it against a background, even if the background is relatively warm. [/QUOTE]
