personal favorite, this system transmits microwave pulses that reflect off of cloud particles in the atmosphere.\u00a0 Their returned signal tells us about the cloud mass, the speed of the cloud droplets, and other cloud properties.\u00a0 It operates with a motion compensating platform that does a great job of keeping the radar pointing vertical in the face of ship motions.<\/span><\/li>\n<li><span style=\"color: #000000\">Microwave Radiometer:\u00a0 This system operates at a similar frequency to the cloud radar, but passively measures downwelling microwave radiation from the atmosphere that contains information on the amount of liquid water and water vapor, and some information on the temperature profile.<\/span><\/li>\n<li><span style=\"color: #000000\">Ceilometer:\u00a0 This is a fancy laser that operates in the near-IR (so we can\u2019t see it), telling us about the distance to the cloud base.<\/span><\/li>\n<li><span style=\"color: #000000\">Wind Profiling Radar:\u00a0 Similar concept to the cloud radar, except with a much longer wavelength such that the returned energy reflects from refractive index gradients in the atmosphere.\u00a0 Measurements in multiple directions can be interpreted together to give a horizontal wind profile.\u00a0 Birds have enjoyed perching on the antenna backplane, and we may see them in the data at times.<\/span><\/li>\n<li><span style=\"color: #000000\">Sea Snake:\u00a0 This resembles a hose simply thrown over the side of the ship.\u00a0 It floats along the top of the ocean measuring temperature.<\/span><\/li>\n<\/ul>\n<div id=\"attachment_180\" style=\"width: 260px\" class=\"wp-caption alignleft\"><img loading=\"lazy\" decoding=\"async\"
