Revolutionary Heat Data Collection from Polar Regions
NASA’s latest climate mission, PREFIRE, has started to gather crucial data on far-infrared radiation emitted by the Arctic and Antarctic. This breakthrough is set to reshape our understanding of how climate change influences these regions, enhancing our capability to anticipate future climate impacts.
The PREFIRE mission employs two CubeSats, launched in May and June respectively, to collect this essential data. The first satellite began transmitting data in early July, with its twin following suit later that month. Data release is pending resolution of a GPS issue on the second CubeSat.
By focusing on far-infrared radiation, PREFIRE aims to uncover how atmospheric water vapor and clouds impact heat escape from Earth. These elements are key contributors to the greenhouse effect, trapping heat and escalating global temperatures.
“We are continually seeking innovative methods to observe our planet,” said Karen St. Germain from NASA. PREFIRE exemplifies how collaboration with universities and industry can drive cutting-edge science.
The Role of Polar Regions in Earth’s Heat Balance
The Sun’s energy is primarily absorbed in the tropics, with weather and ocean currents redistributing this heat toward the poles. Polar environments then emit much of this energy as far-infrared radiation. PREFIRE’s mission is to provide the first systematic measurements of these emissions.
Tristan L’Ecuyer, PREFIRE’s principal investigator, expressed excitement over the incoming data. “With PREFIRE, we’re seeing the full energy spectrum Earth radiates into space for the first time, which is crucial for understanding climate change,” he remarked.
This visualization of PREFIRE data showcases brightness temperatures, indicating the intensity of radiation emitted from Earth. The color spectrum from yellow to blue presents varying emission levels, correlating to surface temperatures and atmospheric conditions.
Key features of the PREFIRE mission include:
- Systematic measurements of far-infrared emissions
- Enhanced understanding of the greenhouse effect
- Collaboration between NASA, universities, and industry partners
Visualizing Far-Infrared Emissions
A recent visualization highlights mid-infrared emissions captured in early July by the first PREFIRE CubeSat. It zooms in on Greenland, revealing how far-infrared emissions fluctuate through the atmosphere. This detailed observation is significant for climate research.
The CubeSats operate in asynchronous orbits, passing over the same polar regions within hours. This allows for a time series of measurements, vital for studying short-lived phenomena like ice sheet melting or cloud formation and their effects on far-infrared emissions.
Such data is invaluable for scientists aiming to understand how transient events in the polar regions influence global climate. The time-series data offers a novel perspective on these rapid changes.
The PREFIRE mission, managed by NASA’s Jet Propulsion Laboratory, involves multiple partners. Blue Canyon Technologies built the CubeSats, while the University of Wisconsin-Madison handles data processing and analysis, ensuring comprehensive study of the gathered information.
Collaborative Efforts Behind PREFIRE
The PREFIRE mission is a joint endeavor between NASA and the University of Wisconsin-Madison. This collaboration underscores the importance of uniting academic and industry expertise to tackle climate challenges.
Managed by NASA’s Jet Propulsion Laboratory, the mission leverages advanced spectrometers to capture detailed far-infrared radiation data. This technology is critical for understanding how our planet’s polar regions are responding to climate change.
Blue Canyon Technologies played a pivotal role in constructing and operating the CubeSats, enabling the PREFIRE mission to achieve its ambitious goals. The seamless integration of these advanced technologies is a testament to innovative engineering.
The University of Wisconsin-Madison is at the forefront of processing and analyzing the data collected by PREFIRE. Their expertise ensures that this mission not only gathers data but also translates it into actionable insights for climate science.

Why does it always have to be CubeSats? Aren’t there better alternatives?
