Measurements of Radiation in the Atmosphere

The recent summit meeting held in Kyoto, Japan, has brought world-wide attention to the issue of global climate change. For the past 5 years, the Department of Energy's Atmospheric Radiation Measurement - Unmanned Aerospace Vehicle (ARM-UAV) Program has been investigating the largest source of uncertainty in global warming; the interaction of solar radiant energy with clouds. As the program name implies, ARM-UAV is fostering the development of UAVs and developing specialized instruments for measurements related to climate research.
