The eruption of a volcano under the Eyjafjallajokull glacier of Iceland on Wednesday, April 14, sent ripple effects around the globe as it halted international flights to and from Northern Europe. Airborne volcanic ash posed a threat to jet engines, and to prevent disaster, air traffic controllers grounded planes. From the earliest moments of the eruption, a global network of Volcanic Ash Advisory Centers began monitoring the ash plume and the appropriate centers issued advisories about flow of the ash through the atmosphere. There are nine such centers, each responsible for a defined geographic region. (More) (Video clip) (Image of ash cloud)

Fifty years ago today, the world’s first weather satellite lifted off from Cape Canaveral, Fla., and opened a new and exciting dimension in weather forecasting. Top leaders from Commerce’s NOAA and NASA hailed the milestone as an example of their agencies’ strong partnership and commitment to flying the best satellites today and beyond. The first image from the satellite, known as TIROS-1, was a fuzzy picture of thick bands and clusters of clouds over the United States. An image captured a few days later revealed a typhoon about 1,000 miles east of Australia. TIROS-1, a polar-orbiting satellite, weighed 270 pounds and carried two cameras and two video recorders.

By combining the best of two different distance measurement approaches with a super-accurate technology called an optical frequency comb, researchers at Commerce’s National Institute of Standards and Technology (NIST) have built a laser ranging system that can pinpoint multiple objects with nanometer precision over distances up to 100 kilometers. The novel LIDAR (“light detection and ranging”) system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant space-based platform to search for new planets.
