NASA Scientists Find “Faces” in Earth’s Atmosphere
One of my favorite parts of being a human is my sighted human ability to find a face in pretty much anything. I’m hoping NASA scientists Lawrence Coy and Steven Pawson feel the same way, given this story from Earth Observatory about their hobby of finding faces in their data:
They spotted all of these “faces” while examining visualizations of wind and temperature data from a reanalysis called the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2). The reanalysis incorporates weather data from satellites and several other sources to simulate atmospheric conditions on a global scale.
“The best time to find faces is in the winter in the polar regions of the northern hemisphere,” Pawson said. “That’s when the dark conditions of the ‘polar night’ lead to a ring of westerly winds in the stratosphere that atmospheric scientists have long called the stratospheric polar vortex or circumpolar vortex.”
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
