Featured Field Campaign Presentations

Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE)

The Coast-Urban-Rural Atmospheric Gradient Experiment (CoURAGE) is expected to start in December 2024 and run through November 2025 in Baltimore, Maryland. The campaign will study surface-atmosphere interactions around Baltimore to see how they influence the city’s climate. With data provided from multiple sites in and around the city, CoURAGE will be able to document the degree to which different surface conditions around the region can change Baltimore’s atmospheric environment.

CoURAGE will contribute to the Baltimore Social-Environmental Collaborative (BSEC), one of four recently funded DOE Urban Integrated Field Laboratories.

Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE)

The Eastern Pacific Cloud Aerosol Precipitation Experiment (EPCAPE), which kicked off in La Jolla, California, in February 2023 and is set to close operations in February 2024, will explore aerosol indirect effects on stratocumulus clouds to help improve their representation in earth system models. EPCAPE includes the deployment of the first ARM Mobile Facility on the Ellen Browning Scripps Memorial Pier and a scanning cloud radar on Mount Soledad less than a mile inland.

As part of EPCAPE, researchers will also investigate how pollution from the nearby Los Angeles metropolitan area affects marine aerosols and, by extension, the clouds near San Diego.

Surface Atmosphere Integrated Field Laboratory (SAIL)

The Surface Atmosphere Integrated Field Laboratory (SAIL) field campaign, which operated from September 2021 to June 2023, took place in the 300-square-kilometer (116-square-mile) East River Watershed near Crested Butte, Colorado. As part of SAIL, a portable ARM observatory provided valuable atmospheric data that researchers can use to develop detailed measurements of mountainous water-cycle processes pertaining to the Colorado River, which supplies water for 40 million people in the Western United States.

By using data from SAIL and co-located fieldwork, researchers from national laboratories, universities, research centers, and agencies are gaining an atmosphere-through-bedrock understanding of mountainous water cycles.

TRacking Aerosol Convection interactions ExpeRiment (TRACER)

The TRacking Aerosol Convection interactions ExpeRiment (TRACER), which ran from October 2021 through September 2022, provided convective cloud observations with high space and time resolution over a broad range of environmental and aerosol conditions in the Houston, Texas, region.

As part of TRACER, ARM deployed a portable observatory southeast of downtown Houston, a scanning precipitation radar south of downtown, and an ancillary site southwest of the city, where tethered balloon systems were launched. Together, these ARM measurements are helping researchers better understand the variability of aerosols and meteorology between the urban Houston area and surrounding rural environments.
