Leveraging publicly available social media posts could help disaster response agencies quickly identify impacted areas in need of assistance, according to a Penn State-led team of researchers.

D is the image C after it has been classified for water pixels. E is a close-up of C, showing the stranded truck. F is the same truck in a Flickr post.  Image: Guido Cervone / Penn State

Astronomers have made a significant step toward confirming a proposed explanation for how solar flares accelerate charged particles to speeds nearly that of light.

January 26, 2016 | Weather forecasts have become increasingly more reliable thanks to improvements over the past several decades in computer modeling and observational equipment. However, when it comes to severe weather, that reliability typically begins to deteriorate beyond a two-day forecast.

December 21, 2015 | Here's a look at 10 of the most popular stories from 2015, as measured by traffic to our website. This year, we've also added a bonus category: Visualization of the Year. 1. Invisible waves visualized For the first time, an NCAR-led team of scientists has found a way to simulate the propagation of gravity waves toward space.

November 6, 2015 | Three hundred years ago, the Sun began to wake up. For 70 years—from about 1645 to 1715—the Sun had been eerily quiet, with very few sunspots erupting on its surface. This prolonged period of muted activity, known as the Maunder Minimum, is the most dramatic so-called "grand minimum" ever recorded by humans.

October 21, 2015 | NCAR scientists have demonstrated how new types of satellite data could improve how agencies monitor and forecast air quality, both globally and by region. The scientists used computer simulations to test a method that combines analysis of chemistry-climate model output with the kind of data that could be obtained from a planned fleet of geostationary satellites, each of which would view a large area of Earth on a continuous basis from high orbit.
