In Aug. 2024, a team of NASA researchers and partners gathered in Missoula, to test new drone-based technology for localized forecasting, or micrometeorology. Researchers attached wind sensors to a drone, NASA\u2019s Alta X quadcopter, aiming to provide precise and sustainable meteorological data to help predict fire behavior.<\/p>\n<\/p>\n

Wildfires are increasing in number and severity<\/a> around the world, including the United States, and wind is a major factor. It leads to unexpected and unpredictable fire growth, public threats, and fire fatalities, making micrometeorology a very effective tool to combat fire.<\/p>\n<\/p>\n

Mounted on top of the drone is a unique infrastructure designed at NASA\u2019s Langley Research Center in Hampton,Virginia, to carry sensors that measure wind speed and direction into the sky. On the ground, UAS pilot in command Brayden Chamberlain performs final pre-flight checks. <\/div>\n

The campaign was run by NASA\u2019s FireSense<\/a> project, focused on addressing challenges in wildland fire management by putting NASA science and technology in the hands of operational agencies.<\/p>\n<\/p>\n

\u201cEnsuring that the new technology will be easily adoptable by operational agencies such as the U.S. Forest Service and the National Weather Service was another primary goal of the campaign,\u201d said Jacquelyn Shuman, FireSense project scientist at NASA\u2019s Ames Research Center in California\u2019s Silicon Valley.<\/p>\n<\/p>\n

The FireSense team chose the Alta X drone because the U.S. Forest Service already has a fleet of the quadcopters and trained drone pilots, which could make integrating the needed sensors \u2013 and the accompanying infrastructure \u2013 much easier and more cost-effective for the agency.<\/p>\n<\/p>\n

Behind Chamberlain, the custom structure attached to the quadcopter holds a radiosonde (small white box) and an anemometer (hidden from view), which will collect data on wind speed and direction, humidity, temperature, and pressure.<\/div>\n

The choice of the two sensors for the drone\u2019s payload was also driven by their adoptability.<\/p>\n<\/p>\n

The first, called a radiosonde, measures wind direction and speed, humidity, temperature, and pressure, and is used daily by the National Weather Service. The other sensor, an anemometer, measures wind speed and direction, and is used at weather stations and airports around the world.<\/p>\n<\/p>\n

\u201cAnemometers are everywhere, but are usually stationary,\u201d said Robert McSwain, the FireSense uncrewed aerial system (UAS) lead, based at NASA\u2019s Langley Research Center in Hampton, Virginia. \u201cWe are taking a sensor type that is already used all over the world, and giving it wings.\u201d<\/p>\n

Both sensors create datasets that are already familiar to meteorologists worldwide, which opens up the potential applications of the platform.<\/p>\n<\/p>\n

Current Forecasting Methods: Weather Balloons<\/h2>\n<\/p>\n

Traditionally, global weather forecasting data is gathered by attaching a radiosonde to a weather balloon and releasing it into the air. This system works well for regional weather forecasts. But the rapidly changing environment of wildland fire requires more recurrent, pinpointed forecasts to accurately predict fire behavior. It\u2019s the perfect niche for a drone.<\/p>\n<\/p>\n

\u201cThese drones are not meant to replace the weather balloons,\u201d said Jennifer Fowler, FireSense\u2019s project manager at Langley. \u201cThe goal is to create a drop-in solution to get more frequent, localized data for wildfires \u2013 not to replace all weather forecasting.\u201d<\/p>\n<\/p>\n

Drones Provide Control, Repeat Testing, Sustainability<\/h2>\n<\/p>\n

Drones can be piloted to keep making measurements over a precise location \u2013 an on-site forecaster could fly one every couple of hours as conditions change \u2013 and gather timely data to help determine how weather will impact the direction and speed of a fire. <\/p>\n<\/p>\n

Fire crews on the ground may need this information to make quick decisions about where to deploy firefighters and resources, draw fire lines, and protect nearby communities.<\/p>\n<\/p>\n

A reusable platform, like a drone, also reduces the financial and environmental impact of forecasting flights.\u00a0<\/p>\n<\/p>\n

\u201cA weather balloon is going to be a one-off, and the attached sensor won\u2019t be recovered,\u201d Fowler said. \u201cThe instrumented drone, on the other hand, can be flown repeatedly.\u201d<\/p>\n<\/p>\n

The Missoula Campaign<\/strong><\/h2>\n<\/p>\n

Before such technology can be sent out to a fire, it needs to be tested. That\u2019s what the FireSense team did this summer.<\/p>\n<\/p>\n

\n
\n
\n
\"Smoke<\/a><\/figure>
\n
Smoke from the nearby Miller Peak Fire drifts by the air control tower at Missoula Airport on August 29, 2024. Miller Peak was one of several fires burning in and around Missoula that month, creating a smokey environment which, combined with the mountainous terrain, made the area an ideal location to test FireSense\u2019s new micrometeorology technology.<\/div>\n
NASA\/Milan Loiacono<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n

McSwain described the conditions in Missoula as an \u201calignment of stars\u201d for the research: the complex mountain terrain produces erratic, historically unpredictable winds, and the sparsity of monitoring instruments on the ground makes weather forecasting very difficult. During the three-day campaign, several fires burned nearby, which allowed researchers to test how the drones performed in smokey conditions.<\/p>\n<\/p>\n

A drone team out of NASA Langley conducted eight data-collection flights in Missoula. Before each drone flight, student teams from the University of Idaho in Moscow, Idaho, and Salish Kootenai College in Pablo, Montana, launched a weather balloon carrying the same type of radiometer.<\/p>\n<\/p>\n

Once those data sets were created, they needed to be transformed into a usable format. Meteorologists are used to the numbers, but incident commanders on an active fire need to see the data in a form that allows them to quickly understand which conditions are changing, and how. That\u2019s where data visualization partners come in. For the Missoula campaign, teams from MITRE, NVIDIA, and Esri joined NASA in the field.<\/p>\n<\/p>\n

Measurements from both the balloon and the drone platforms were immediately sent to the on-site data teams. The MITRE team, together with NVIDIA, tested high-resolution artificial intelligence meteorological models, while the Esri team created comprehensive visualizations of flight paths, temperatures, and wind speed and direction. These visual representations of the data make conclusions more immediately apparent to non-meteorologists.<\/p>\n<\/p>\n

What\u2019s Next?<\/strong><\/h2>\n<\/p>\n

Development of drone capabilities for fire monitoring didn\u2019t begin in Missoula, and it won\u2019t end there.<\/p>\n<\/p>\n

\u201cThis campaign leveraged almost a decade of research, development, engineering, and testing,\u201d said McSwain. \u201cWe have built up a UAS flight capability that can now be used across NASA.\u201d<\/p>\n

The FireSense project is led by NASA Headquarters in Washington and sits within the Wildland Fires program, with the project office based at NASA Ames. The goal of FireSense is to transition Earth science and technological capabilities\u00a0to operational wildland fire management agencies, to\u00a0address challenges\u00a0in U.S. wildland fire management before, during, and after a fire.\u00a0<\/em><\/p>\n
