Argonne’s collaborations in Hawaii and across the United States have led to groundbreaking discoveries and development of new technologies that help meet the nation’s needs for reliable energy, economic prosperity, and security.
Argonne researchers use AI-enabled sensors to gather climate and pollutant data that will aid in wildfire recovery
The August 2023 wildfire that devastated Lahaina, Hawaii, was spurred by dry conditions, high temperatures and strong winds. Researchers are monitoring the area to better understand the community’s recovery process and provide new air quality and weather data. This is part of a National Science Foundation project. The team includes researchers from Northwestern University and the University of Hawaii using a specialized artificial intelligence-enabled sensor designed at the U.S. Department of Energy’s (DOE) Argonne National Laboratory.
The research team has deployed an instrument featuring ten sensors, called a Sage node, near Volcanoes National Park on Hawaii Island. It is part of a multi-hazard monitoring and detection station for natural disasters. The project is in collaboration with professors at University of Hawai‘i at Mānoa. Overall, the project will gather climate and pollutant data to aid clean-up activities in Lahaina and will provide data to guide recovery planning.
Argonne deploys HEADOUT, a hurricane impact simulator for Hawaii’s long-term grid planning
Armed with HEADOUT, a hurricane damage assessment tool developed by scientists at the Argonne, government officials and power suppliers in Hawaii were able to collect data and prepare for two historic storms that hit the islands in 2018.
Initially categorized as a Category 4 hurricane, Olivia was downgraded to a tropical storm before making landfall and causing severe flooding and wind damage. It was the first tropical cyclone to hit the islands of Maui and Lanai in recorded history. With torrential rainfall and strong winds, Category 5 Hurricane Lane was the wettest storm on record, at one point dropping 58 inches of rain along the slopes of Mauna Loa, one of Hawaii’s active volcanoes.
Argonne originally developed HEADOUT as a quick turnaround tool to estimate a storm’s impact on the power grid, but now it offers much more. Besides providing real-time support for government officials and power suppliers, HEADOUT offers training and exercise support as well as long-term grid planning for DOE as part of a resilience modeling effort for North America.
Argonne’s mobile climate observatory gathers data on Honolulu-to-Los Angeles research campaign
Making accurate climate-relevant observations where such data is scarce or difficult to capture is the mission of the Atmospheric Radiation Measurement (ARM) mobile facility. Developed in 2010 and maintained and operated by Argonne, this climate research facility’s suite of atmospheric sensing instruments records the properties of clouds, precipitation, aerosol particles and radiation in a variety of environments.
In its first marine-based campaign, ARM deployed this mobile facility aboard a cargo container ship in the Pacific Ocean, collecting data for a year while the ship pursued its scheduled route between Honolulu and Los Angeles. Led by principal investigator Ernie Lewis of the DOE’s Brookhaven National Laboratory in Upton, New York, the campaign provided the first observations of the elusive cloud transitions that happen over the North Pacific. The rich data from this research enabled scientists to study the transition from low, drizzly stratocumulus clouds near California to puffy cumulus clouds closer to Hawaii. To support ocean-based deployments, ARM incorporated wireless communication technology as well as platforms that could withstand ship motion and instruments to observe the properties of the ocean surface.
Scientists say low marine boundary layer clouds significantly influence Earth’s climate by reflecting sunlight, thereby cooling the Earth’s surface. Findings from this work were published in 2019 by the Quarterly Journal of the Royal Meteorological Society.
