Remote-sensing devices that scientists use to observe the atmosphere come in two varieties: passive sensors and active sensors. A passive sensor detects light or heat of certain wavelengths that enters its field of view. An active sensor probes the environment by sending out a pulse of energy and measuring how long it takes the signal to return and how its frequency, wavelength, or intensity has changed. The energy pulse can be microwaves or radio waves (radar) or light (lidar). The images...
