News & Events

The Atmospheric Radiation Measurement (ARM) User Facility produces news and features, data announcements, event announcements, and highlights about its activities to keep users informed.

This ARM Mobile Facility—a series of containers outfitted with sophisticated atmospheric and meteorological sampling equipment—will operate from December 2024 to November 2025 in Baltimore, Maryland as part of the Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE). The CoURAGE main site will be located here, on this former high school athletic field at Morgan State University’s Clifton Park location.

Data Announcements

This sample plot shows droplet number concentration from the EPCAPE ARM Mobile Facility site in La Jolla, California. The plot shows calculated droplet number concentration for two different periods. The droplet number concentration is generally seen between 0.0 and 0.4 m-3. Image is provided by Chitra Sivaraman, Pacific Northwest National Laboratory.

New and Updated Cloud Droplet Number Concentration Data Available

The Droplet Number Concentration (NDROP) value-added product has been processed for the 2023–2024 Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE). In addition, the VAP has been updated to use reprocessed multifilter rotating shadowband radiometer data from the Eastern North Atlantic observatory.
