Hurricane Dorian off the coast of Florida, as seen by the small satellite TEMPEST-D at 2 a.m. EDT on Sep. 3, 2019 (11 p.m PDT on Sept. 2, 2019). The layers in the animation reveal slices of the hurricane from four depths, taken at different radio wavelengths. The vertical view of Dorian highlights where the storm is strongest in the atmosphere. The colors in the animation show the heavy rainfall and moisture inside the storm. The least-intense areas of rainfall are shown in green, while the most intense are yellow, red and pink.
