Multiple Views of Hurricane Dorian from Different NASA Satellites

Three photos of Hurricane Dorian, as seen by a trio of NASA’s Earth-observing satellites Aug. 27-29, 2019. The information despatched by the spacecraft revealed in-depth views of the storm, together with detailed heavy rain, cloud top and wind. Credit score: NASA/JPL-Caltech

A number of devices and spacecraft from NASA’s Jet Propulsion Laboratory in Pasadena, California, have eyes on Hurricane Dorian, capturing differing types of knowledge from the storm.

An infrared picture of Hurricane Dorian, as seen by the AIRS instrument aboard NASA’s Aqua satellite tv for pc at 1:30 p.m. EDT (10:30 a.m. PDT) on Aug. 29, 2019. The big purple areas are chilly clouds, carried excessive into the environment by deep thunderstorms. Blue and inexperienced present hotter areas with much less rain clouds, whereas orange and crimson symbolize principally cloud-free air. Credit score: NASA/JPL-Caltech

NASA’s Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite tv for pc, senses emitted infrared and microwave radiation from Earth. The knowledge is used to map such atmospheric phenomena as temperature, humidity, and cloud quantities and heights. Within the AIRS imagery of Dorian, captured throughout the afternoon (native time) of Aug. 29, 2019, the massive purple space signifies very chilly clouds carried excessive into the environment by deep thunderstorms. These clouds are additionally related to heavy rainfall. Blue and inexperienced point out hotter areas with shallower rain clouds, whereas the orange and crimson areas symbolize principally cloud-free air.

Hurricane Dorian off the coast of Puerto Rico, as seen by the small satellite tv for pc TEMPEST-D on Aug 28, 2019 (native time). The colours within the picture reveal the heavy rain and moisture contained in the storm. The least intense areas of rainfall are proven in inexperienced and most intense are yellow and pink.

Within the second picture, TEMPEST-D – a weather-observing satellite tv for pc the dimensions of a cereal field – captured imagery of Hurricane Dorian off the coast of Puerto Rico within the early morning hours (native time) of Aug. 28, 2019. At a vantage level 250 miles (400 kilometers) above the storm, the CubeSat used its miniaturized radio-wave-based instrument to see by the clouds, revealing areas with heavy rain and moisture being pulled into the storm. The inexperienced colours present moisture spiraling into the storm’s heart, and the yellow to pink colours correspond to essentially the most intense rainfall. TEMPEST-D – brief for Temporal Experiment for Storms and Tropical Programs Demonstration – is an experiment in shrinking climate satellites to a measurement that makes them cheap sufficient to be produced in multiples. The objective is eventual real-time storm protection with many small satellites that may monitor storms world wide.

On, August 27, 2019, NASA’s CloudSat satellite tv for pc handed over Dorian, nonetheless a tropical storm on the time, close to Puerto Rico. CloudSat makes use of a sophisticated cloud-profiling radar that “slices” by clouds giving us the power to see how tall they’re, the place the totally different cloud layers are, and the place the heavier bands of rain are discovered inside the storm system. The 3D animation reveals Dorian when it had most sustained winds of 52 mph (84 kph) with some of its cloud tops extending about 9 miles (15 kilometers) into the environment. The colours symbolize the dimensions of water or ice droplets contained in the storm — deep crimson and pink point out bigger droplets with areas of average and heavy rainfall.

NASA collects knowledge from house, air, land, and sea to extend our understanding of our house planet, enhance lives and safeguard our future.

AIRS, together with the Superior Microwave Sounding Unit (AMSU), offers a 3D take a look at Earth’s climate and local weather. Launched into Earth orbit in 2002, the AIRS and AMSU devices are managed by JPL beneath contract to NASA. TEMPEST-D is a technology-demonstration mission led by Colorado State College and managed by JPL in partnership with Blue Canyon Applied sciences and Wallops Flight Facility in Virginia. The mission is sponsored by NASA’s Earth Ventures program and managed by the Earth Science Expertise Workplace. The radiometer instrument was constructed by JPL and employs high-frequency microwave amplifier expertise developed by Northrop Grumman. CloudSat can be managed by JPL, which developed the radar instrument, with {hardware} contributions from the Canadian House Company. Colorado State College offers scientific management and science knowledge processing and distribution.
