The ARM Program—the Department of Energy's largest global change research program—was created to help resolve scientific uncertainties related to global climate change. Its specific focus is on the crucial role of clouds and their influence on radiative feedback processes in the atmosphere.

The U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Program invites news media to observe a team of 25 climate researchers from the United States, Australia, and the United Kingdom as they prepare to launch simultaneous ground, sea, and sky operations during the Tropical Warm Pool International Cloud Experiment this coming winter. Sandia National Laboratories, home to ARM's Unmanned Aerospace Vehicle (ARM-UAV) program, is hosting the three-day simulation, where researchers will conduct weather briefings and mission planning to reflect actual field operations and flight scenarios during the complex experiment. News media are invited to observe the simulation exercises on Thursday, September 8, between 10 am and 4 pm, and talk with scientists leading the experiment.

The experiment, organized jointly by the ARM Program and the Australian Bureau of Meteorology, begins in January 2006, in the region around Darwin, Australia. It will involve the use of atmospheric sensing equipment located at multiple ground stations, on a ship operating off the coast, and on an instrumented fleet of aircraft. Data collected during the month-long experiment will be used to validate and improve cloud and global models for climate change research and for assessing the environmental impacts of tropical monsoons.
