Peering Into the Heart of Clouds: NASA’s CloudSat Wraps a Revolutionary Journey

A thousand times more delicate than typical ground-based weather condition radars, it yielded a brand-new vision of clouds– not as flat images on a screen however as 3D pieces of environment bristling with ice and rain.For the very first time, researchers could observe clouds and rainfall together, said Graeme Stephens, the missions primary investigator at NASAs Jet Propulsion Laboratory in Southern California. Considering that its launch, weve likewise come a long method in understanding how clouds are able to cool and heat up the atmosphere and surface, as well as how they can cause airplane icing.CloudSat information has informed thousands of research publications and continues to assist scientists make key discoveries, including how much ice and water clouds include worldwide and how, by trapping heat in the atmosphere, clouds speed up the melting of ice in Greenland and at the poles.Weathering the StormOver the years, CloudSat flew over powerful storm systems with names like Maria, Harvey, and Sandy, glancing underneath their swirling canopies of cirrus clouds. Its Cloud Profiling Radar stood out at permeating cloud layers to help scientists explore how and why tropical cyclones intensify.Across the life of CloudSat, numerous potentially mission-ending issues happened associated to the spacecrafts battery and to the response wheels used to control the satellites orientation. The two spacecraft signed up with an international constellation of weather condition- and climate-tracking satellites in Earth orbit.Radar and lidar are considered “active” sensing units due to the fact that they direct beams of energy at Earth– radio waves in the case of CloudSat and laser light in the case of CALIPSO– and determine how the beams reflect off the clouds and great particles (aerosols) in the atmosphere. Their overlapping radar-lidar footprint cut through the vertical structure of the environment to study thin and thick clouds, as well as the layers of airborne particles such as dust, sea salt, ash, and soot that can influence cloud formation.The impact of aerosols on clouds stays a key question for global warming forecasts.
