Infared cameras.
by comparinig the xmit line to the recieve line and look for differences
If the smoke is not enough to be detected visually, it can be detected by infra-red (heat sensors).
Infrared radiation cannot be seen by the naked eye, but it can be detected as heat. It is emitted by all objects with a temperature above absolute zero and is commonly used in heat-sensing devices such as thermal cameras.
Breezes are created when there are specific heat differences between land and ocean.
Heat is a form of energy... noticeable only by the temperature differences

Hot stimuli are detected by heat-sensitive receptors called thermoreceptors, while cold stimuli are detected by cold-sensitive receptors in the skin known as cold thermoreceptors. These receptors are specialized nerve endings that are able to detect changes in temperature and transmit this information to the brain to generate the sensation of heat or cold.
No, heat is not visible to the human eye. We can only see objects that emit or reflect light, but heat itself is a form of energy that is detected by our skin or other instruments.
Heat that can be measured or felt is called sensible heat. Sensible heat refers to the heat exchange that causes a change in temperature and can be detected by the human senses or measured using a thermometer.
Heat waves are detected through a combination of monitoring temperature anomalies over a period of time and comparing them to historical data. Weather stations and satellites are used to collect temperature readings, which are analyzed to identify extended periods of abnormally high temperatures. Meteorologists also consider factors such as humidity and heat index to determine the severity and duration of a heat wave.
In some people who have sensitive joints, such as with arthritis, subtle differences in pressure can be detected. Differences in pressure precede changes in weather, but that is the extent to which they could actually "forecast" the weather.
