Record of largest meteorite to strike earth this decade detected during LIDAR calibration. The LIDAR is able to remotely measure the temperature, wind velocity and aerosol concentration as a function of altitude from the lower stratosphere (10 km altitude) to the upper mesosphere (90 km altitude). The information is obtained by sending pulses of green laser light into the sky and measuring the extremely small spectral changes that take place when the light is scattered by atmospheric gases and aerosols. The information collected will be used to assess long-term climate trends and to better understand atmospheric motions. Information gathered by the LIDAR will contribute to several international programs.
