Learn more about how NASAs modeling and data assimilation systems produce estimates of Earth’s atmospheric state. NASA Goddard shared this video on Youtube!
Better and faster computers have improved how we model and study Earth. More information is the other piece of the puzzle improving how we model and forecast our planet’s atmosphere.
Since 1980, the 10th anniversary of Earth Day, the number of observing systems, which include satellites, weather balloons, and even instruments flown on commercial airlines, have dramatically increased — from 175,000 observations gathered over a six-hour period in 1980 to around 5 million observations in 2018.
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.
