Peter Chylek is the remote-sensing team leader for Los Alamos National Laboratory's (LANL) International, Space, and Response Division. Chylek’s work builds on Los Alamos’ history of using satellites to detect the illicit production of weapons of mass destruction. One of those satellites, the Multispectral Thermal Imager (MTI), has circled the planet since March 2000, collecting images of the Earth with instruments that see changes in light and heat that the human eye cannot. While looking for the telltale gases, dusts, and heat produced by chemical or nuclear activity, the MTI has produced mountains of environmental data.
