MISR Imagery of Hurricane Michael
NASA's Terra spacecraft shows a three dimensional view of Hurricane Michael and combines two of MISR's nine camera angles. MISR's stereo anaglyph shows a three-dimensional view of Michael and combines two of MISR's nine camera angles. Using 3D red-blue glasses, you can see the 3D effect. Apparent in the 3D stereo anaglyph as well as the height field are a number of bright "clumps." These are groups of strong thunderstorms embedded within the larger circulation of the hurricane. Known as "vortical hot towers," the presence of these features indicates rapid transport of heat energy from the ocean surface into the storm, typically indicative of rapid intensification of the hurricane. In fact, between 11 a.m. and 2 p.m. EDT, while MISR imaged the hurricane, the estimated central pressure dropped 8 hPa and the maximum sustained winds increased about 12 mph (19 kph) and over the next 24 hours Hurricane Michael intensified from a Category 2 to a Category 4 storm.

MISR Imagery Hurricane Michael 
MISR (a NASA instrument that flies aboard the Terra satellite) carries nine cameras fixed at different angles, each of which viewed Michael over the course of approximately seven minutes when it was just off Florida's west coast on Tuesday October 9, 2018. This composite image shows the view from the central, downward-pointing camera (left), the calculated cloud-top heights (middle), and wind velocity vectors (right) superimposed on the image. The length of the arrows is proportional to wind speed and the colors show the altitude of the cloud tops in kilometers. Images from the nine views are used to calculate the height of the cloud tops, and the motion of the clouds between the views provides information on wind speed and direction.

ISS Imagery Hurricane Michael
These visible-wavelength (RGB) handheld digital camera images of the Hurricane Michael eyewall were taken by astronauts onboard the International Space Station on October 10, 2018 as they passed over the storm. Once the storm has passed and cloud cover lessens, requests to document flooding, changes to the land surface, etc. can be sent to the ISS crew. Imagery of this type is then georeferenced by the Earth Science and Remote Sensing Unit at JSC.

NASA MISR Image
NASA MISR Image  NASA’s MISR (Multi-angle Imaging SpectroRadiometer) instrument on-board the Terra satellite captured Hurricane Michael with the eye in mid swath on October 9, 2018. This MISR image was captured during Terra orbit 100049. MISR carries nine cameras to view the earth at nine widely-spaced angles and provides calibrated images in four spectral bands at each of the angles.

NASA's ARIA Along-Track Deformation Map
NASA's ARIA Along-Track Deformation Map Scientists with the Advanced Rapid Imaging and Analysis project (ARIA), a collaboration between NASA’s Jet Propulsion Laboratory in Pasadena, California, and Caltech, also in Pasadena, using synthetic aperture radar (SAR) data from the Japanese Aerospace Exploration Agency (JAXA) Advanced Land Observing Satellite-2 (ALOS-2) PALSAR-2, generated maps of the deformation of Earth’s surface caused by the Sept. 28, 2018 magnitude 7.5 earthquake under Sulawesi island, Indonesia, near the city of Palu. The along-track deformation map measures horizontal deformation in the satellite-track direction, roughly south.  The false-color maps show the amount of permanent surface movement that occurred almost entirely due to the quake, as viewed by the satellite, during a 42-day interval between two ALOS-2 wide-swath images acquired on August 20 and October 1, 2018 (both UTC).

GPM IMERG precip measurements from Hurricane Michael
Video of GPM Rainfall Data From Michael This animation shows the NASA Integrated Multi-satellitE Retrievals for GPM (IMERG) rainfall accumulation estimates from Hurricane Michael October 1- 5, 2018 when rainfall was getting more concentrated over the western Caribbean. The Global Precipitation Measurement mission or GPM's constellation of satellites provides rainfall data to make rainfall estimates. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA. IMERG indicated that rainfall accumulation totals of over 12 inches fell in the Caribbean Sea east of Honduras during this period.

GPM overpass of hurricane michael on 10/8/18
The GPM Microwave Imager (GMI) has 13 channels that view different aspects of the hurricane in different ways. This overpass of Hurricane Michael on Oct. 8th, 2018 shows the combined low, mid, and high-frequency GMI channels along with the retrieved rain rate for the same overpass developed by combining all channels to understand the precipitation structure.
