SAIL radiometers (IMAGE) DOE/Lawrence Berkeley National Laboratory Caption On July 1, 2021, Heath Powers, site manager for the second ARM Mobile Facility, helps set up radiometers for ARM’s Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign in Gothic, Colorado. To his right is site technician Wessley King. The SAIL campaign, which will run from September 2021 to June 2023, will provide insights into mountainous water-cycle processes. Data from the radiometers will be used to help determine the site’s surface energy balance.
