NNSA PRESS RELEASE
The Los Alamos Field Office (DOE/NNSA) of the Department of Energy’s National Nuclear Security Administration has issued a categorical exclusion for Home Atmospheric Radiation Measurement Campaigns – Aerosol Precipitation Experiment in Eastern Pacific Clouds (EPCAPE).
The DOE, Office of Science, in conjunction with Los Alamos National Laboratory (LANL), conducts atmospheric and environmental research and monitoring activities by deploying mobile facilities and equipment (including weather balloons) for 1-2 years at sites across the United States. The DOE and Triad National Security, LLC, LANL’s operating contractor, are offering to deploy equipment and launch weather balloons in support of EPCAPE.
This project will characterize the extent, radiative properties, aerosol interactions, and precipitation characteristics of stratocumulus clouds in the eastern Pacific throughout the year at two coastal sites owned and managed by the Scripps Institute of Oceanography of the United States. ‘University of California, San Diego: The Scripps Pier and the Scripps Pier Sites of Mount Soledad in La Jolla, California. To facilitate data collection, the project plans to launch weather balloons at a rate of two per day, plus 360 additional balloons in spring and summer. About six other weather balloon launches are planned during the establishment of the project. In total, the project proposes to launch approximately 1,100 weather balloons over the one-year duration of the EPCAPE campaign. Activities would be designed in accordance with applicable regulatory requirements and using best management practices. After the data collection period, each site would be restored to pre-project conditions.
