Several NASA views of Hurricane Dorian from space



Several instruments and spacecraft from NASA's Jet Propulsion Laboratory in Pasadena, California, keep track of Hurricane Dorian and capture various types of data from the storm.

  AIRS image

An infrared image of Hurricane Dorian, seen from the AIRS instrument aboard the NASA's Aqua satellite at 13:30. EDT (10:30 am PDT) on August 29, 2019. The large violet areas are cold clouds that are carried high into the atmosphere by deep thunderstorms. Blue and green show warmer areas with less rain clouds, while orange and red are mostly cloudless air. Picture credits: NASA / JPL-Caltech

NASA's Atmospheric Infrared Sounder (AIRS), on board the Aqua satellite, records the infrared and microwave radiation emitted by Earth. The information is used to map atmospheric phenomena such as temperature, humidity and cloud levels and heights. In Dorian's AIRS images, taken in the afternoon (local time) of August 29, 201

9, the large purple area indicates very cold clouds that are carried high into the atmosphere by deep thunderstorms. These clouds are also associated with heavy rainfall. Blue and green indicate warmer areas with shallower rain clouds, while the orange and red areas are mostly cloudless.

  TEMPEST image

Hurricane Dorian off the coast of Puerto Rico, seen from the small satellite TEMPEST-D on August 28, 2019 (local time). The colors in the picture show the heavy rain and humidity inside the storm. The least intense rainfall areas are green and the most intense yellow and pink. Picture credits: NASA / JPL-Caltech

In the second image, TEMPEST-D – a meteorology-sized weather observation satellite – took pictures of Hurricane Dorian off the coast of Puerto Rico in the early morning hours (local time) of August 28, 2019 at a vantage point 400 kilometers above the storm The CubeSat was able to see through the clouds with its miniaturized radio wave instrument and recognize areas with heavy rain and humidity, which were drawn into the storm. The green colors show moisture that winds into the middle of the storm, and the yellow to pink colors correspond to the most intense rainfall. TEMPEST-D – Abbreviation for Temporal Experiment for Storms and Tropical Systems Demonstration – is an experiment in which weather satellites are shrunk to a size that makes them cost-effective enough to be mass-produced. The goal is a real-time storm cover with many small satellites that can track storms around the world.

NASA's CloudSat satellite delivered a 3D animation after driving through Dorian, a tropical storm at that time, near Puerto Rico. CloudSat uses an advanced cloud-profile radar that "cuts" through clouds, allowing us to see their elevation, their different layers, and the areas in which the stronger rainbands are inside the storm system. The animation shows Dorian in maximum wind of 84 km / h with some cloud cover, which extend about 15 km into the atmosphere. The colors represent the size of the water or ice droplets inside the storm: Deep red and pink indicate larger droplets with areas of moderate and heavy precipitation.

NASA collects data from space, air, land and sea to improve our understanding of our home planet, improve life, and secure our future.

AIRS offers 3D technology in conjunction with the Advanced Microwave Sounding Unit (AMSU) View the weather and climate on Earth. The AIRS and AMSU instruments, which were launched in 2002, are managed by JPL on behalf of NASA. TEMPEST-D is a technology demonstration mission led by Colorado State University and managed by JPL in partnership with Blue Canyon Technologies and Wallops Flight Facility in Virginia. The mission is sponsored by NASA's Earth Ventures program and managed by the Earth Science Technology Office. The Radiometer instrument was built by JPL and uses the high-frequency microwave amplifier technology developed by Northrop Grumman. CloudSat is also managed by JPL, which developed the radar instrument with hardware contributions from the Canadian Space Agency. Colorado State University provides scientific leadership and scientific data processing and distribution.

JPL is managed by Caltech in Pasadena for NASA.
