In and around Baltimore, Maryland, scientists, technicians, and students are poised for a year of measuring an urban atmosphere during the Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE).

Scientists share their accomplishments with ARM data during their five-year U.S. Department of Energy Early Career Research Program projects.

Papers pour in from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition, revealing new findings about the data-sparse and vulnerable region.

The Retrieved Number concentration of Cloud Condensation Nuclei (RNCCN) value-added product is now available for evaluation for the Eastern North Atlantic (ENA) atmospheric observatory.

ARM has installed a set of three instruments at a NOAA site in Utqiaġvik (formerly Barrow), Alaska, to help give scientists a richer picture of atmospheric particles in the Arctic.

This product, currently available for three ARM field campaigns, allows users to quickly access key measurements from nearly two dozen ARM Aerial Facility products.

Studies that explore aerosol–cloud–precipitation interactions must account for the different environments in which these processes occur. This effort demonstrates an objective approach based on self-organizing maps (SOMs) to classify the synoptic state (meteorological environment) that is sufficiently general to be applied to any geographical area.

Why does the equilibrated global precipitation rate increase at roughly 2% per K in all global climate models?  Despite the ubiquity of this result, we have not yet had an explanation for it.

Different regimes of aerosol indirect effects and the active regions over the global ocean are studied and identified by analyzing long-term satellite measurements of aerosol and cloud properties.
