The following news release is being issued today by the U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Climate Research Facility. It describes a new phase of a research program taking place in Steamboat Springs, Colorado, to gather data that will improve modeling of Earth’s climate system. Scientists from DOE’s Brookhaven National Laboratory designed and installed the suite of instruments located near Christie Peak, and will continue to play various roles both on location in Colorado and remotely as data are collected and analyzed. For more information about Brookhaven’s role in this research or to interview some of the scientists involved, contact: Karen McNulty Walsh, 631 344-8350,

Scientists Begin 5-month Study of Cloud Life Cycles

Instruments at four mountain sites will gather data to improve climate models

Steamboat Springs, Colorado — Ski season is snow season, and snow season means clouds — exactly what a team of atmospheric scientists in “Ski Town USA” are anticipating. For the next five months, a dense collection of remote-sensing instruments will gather data from the clouds at four different elevations on Mount Werner in the Steamboat Springs ski area. Scientists will use these data to study how clouds — especially those that produce rain and snow — evolve in mountainous terrain. They will use the data to verify the accuracy of measurements used in computer models of the Earth’s climate system.
