Mark Vaughan is a mathematician at NASA’s Langley Research Center in Hampton, Va. He uses math to improve the lidar, or pulsating laser, instrument measurements on NASA’s CALIPSO (Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations) satellite, which collects information on the distribution and movement of clouds and particles, called aerosols, in Earth’s atmosphere. CALIPSO’s lidar instrument works by pulsing laser light through the atmosphere. The way the laser reflects off of things in the atmosphere tells scientists what’s there, like clouds and particles.

Know Your Earth 3.0 Local Connections

“Know Your Earth 3.0, Local Connections” is a partnership among 22 of NASA’s Earth-observing missions. This educational project focuses on educating students, teachers and the public about cutting-edge NASA Earth science research. Each mission has selected a scientist or engineer to be featured on NASA websites throughout April 2013, and many will be speaking about their work at NASA to schools, youth groups and other organizations in their hometowns. One of Know Your Earth 3.0’s main objectives is to provide a local hometown connection to students and the general public and to inspire them into the next generation of science, technology, engineering and mathematics (STEM) careers.
