In addition to looking outward, NASA constantly monitors our own planet using a suite of satellites. In this video, they visualize data taken by the Global Precipitation Measurement Core Observatory of Hurricane Maria two days before it hit Puerto Rico. Instruments on board the satellite measure both liquid and frozen precipitation, giving scientists – and now the public – a glimpse into the heart of a developing hurricane. Be sure to take a look around; it’s a 360-degree video, and I bet it’s even more spectacular in VR. Having a trove of data like this helps researchers better understand the processes that influence a strengthening hurricane, which ultimately allows them to make better predictions about hurricane behavior in order to save lives.

3D Printing Fluids
Most flows vary in three spatial dimensions and time. In experimental fluid dynamics, the challenge is measuring as much of this information as possible. For those who use computational fluid dynamics to study flows, their simulations provide massive amounts of data and the challenge comes in visualizing and processing that data in a useful way. Unless you can find and analyze the important aspects of the simulation results, they’re just a bunch of numbers. As computers have advanced, the size and complexity of simulation results has increased, too, making the task even more difficult. Using technologies like virtual reality projections (above) or 3D printing (below) allow researchers to interact with flow information in completely new but intuitive ways, hopefully leading to new insights into the data.

** The 3D-printed vortices are an image I took of a poster at the APS DFD Gallery of Fluid Motion in 2013, but I’m missing the researchers’ names. If you know whose poster these were from, please let me know (fyfluids [at] gmail [dot] com) so that I can update the credits accordingly. Thanks to Shervin for helping me find the right lab to credit!
