Biography

Dr. Welton has specialized in aerosol related research since 1994, particularly characterization of the optical and physical properties of various aerosol species. In addition, he is an expert in the use of lidar and radiometry to retrieve aerosol and cloud properties. Dr. Welton has been active in lidar research since 1996, and is the Principal Investigator for the NASA Micro Pulse Lidar Network (MPLNET) – a federated network of lidar sites around the world. Dr. Welton was an atmospheric team member on NASA’s Geoscience Laser Altimeter System (GLAS), and is a science team member for the agency’s current lidar mission, CALIPSO. Dr. Welton is also the Deputy Project Scientist for NASA's Glory mission. Glory, scheduled to launch in November 2010, is a climate mission that will obtain detailed information on aerosol properties from space and continue NASA's long term series of solar irradiance measurements. Finally, Dr. Welton is also a member of the science working group formulating the Aerosols, Clouds, and Ecosystems (ACE) mission recommended in the 2007 NRC Earth Sciences Decadal report for NASA.
