Student teams from three U.S. universities became the first to measure what scientists have long predicted: eclipses can generate ripples in Earth\u2019s atmosphere called atmospheric gravity waves. The waves\u2019 telltale signature emerged in data captured during the North American annular solar eclipse on Oct. 14, 2023, as part of the Nationwide Eclipse Ballooning Project (NEBP) sponsored by NASA.<\/p>\n

Through NEBP, high school and university student teams were stationed along the eclipse path through multiple U.S. states, where they released weather balloons carrying instrument packages designed to conduct engineering studies or atmospheric science experiments. A cluster of science teams located in New Mexico collected the data definitively linking the eclipse to the formation of atmospheric gravity waves, a finding that could lead to improved weather forecasting.<\/p>\n

\u201cClimate models are complicated, and they make some assumptions about what atmospheric factors to take into account.\u201d <\/span><\/h2>\n<\/p><\/div>\n

\u201cUnderstanding how the atmosphere reacts in the special case of eclipses helps us better understand the atmosphere, which in turn helps us make more accurate weather predictions and, ultimately, better understand climate change.\u201d<\/p>\n

Catching Waves in New Mexico<\/strong><\/h3>\n

Previous ballooning teams also had hunted atmospheric gravity waves during earlier eclipses, research that was supported by NASA and the National Science Foundation. In 2019, an NEBP team stationed in Chile collected promising data, but hourly balloon releases didn\u2019t provide quite enough detail. Attempts to repeat the experiment in 2020 were foiled by COVID-19 travel restrictions in Argentina and a heavy rainstorm that impeded data collection in Chile.<\/p>\n

Project leaders factored in these lessons learned when planning for 2023, scheduling balloon releases every 15 minutes and carefully weighing locations with the best potential for success.<\/p>\n

\u201cNew Mexico looked especially promising,\u201d said Jie Gong, a researcher in the NASA Climate and Radiation Lab at the agency\u2019s Goddard Space Flight Center in Greenbelt, Maryland, and co-investigator of the research on atmospheric gravity waves. \u201cThe majority of atmospheric gravity sources are convection, weather systems, and mountains. We wanted to eliminate all those possible sources.\u201d<\/p>\n

The project created a New Mexico \u201csupersite\u201d in the town of Moriarty where four atmospheric science teams were clustered: two from Plymouth State University in Plymouth, New Hampshire, and one each from the State University of New York (SUNY) Albany and SUNY Oswego.<\/p>\n

Students began launching balloons at 10 a.m. the day before the eclipse.<\/p>\n

\u201cThey worked in shifts through the day and night, and then everyone was on site for the eclipse,\u201d said Eric Kelsey, research associate professor at Plymouth State and the NEBP northeast regional lead.<\/p>\n

Each balloon released by the science teams carried a radiosonde, an instrument package that measured temperature, location, humidity, wind direction, and wind speed during every second of its climb through the atmosphere. Radiosondes transmitted this stream of raw data to the team on the ground. Students uploaded the data to a shared server, where Gong and two graduate students spent months processing and analyzing it.<\/p>\n

Confirmation that the eclipse had generated atmospheric gravity waves in the skies above New Mexico came in spring 2024.<\/p>\n

\u201cWe put all the data together according to time, and when we plotted that time series, I could already see the stripes in the signal,\u201d Gong said. \u201cI bombarded everybody\u2019s email. We were quite excited.\u201d<\/p>\n

For Students, Learning Curves Bring Opportunity<\/strong><\/h3>\n

The program offered many students their first experience in collecting data. But the benefits go beyond technical and scientific skill.<\/p>\n

\u201cThe students learned a ton through practicing launching weather balloons,\u201d Kelsey said. \u201cIt was a huge learning curve. They had to work together to figure out all the logistics and troubleshoot. It\u2019s good practice of teamwork skills.\u201d<\/p>\n

\u201cAll of this is technically complicated,\u201d Des Jardins said. \u201cWhile the focus now is on the science result, the most important part is that it was students who made this happen.\u201d<\/p>\n
