      Designers at NASA’s Scientific Visualization Studio work alongside researchers and scientists to create high-quality, engaging animations and visualizations of data. This animation shows global carbon dioxide emissions forming and circling the planet.Credit: NASA's Scientific Visualization Studio Captivating images and videos can bring data to life. NASA’s Scientific Visualization Studio (SVS) produces visualizations, animations, and images to help scientists tell stories of their research and make science more approachable and engaging.
      Using the Discover supercomputer at the Center for Climate Simulation at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, visualizers use datasets generated by supercomputer models to create highly detailed, accurate, and stunning visualizations with Hollywood filmmaking tools like 3D modeling and animation.
      Using supercomputing models, SVS visualizers created this data-driven animation of carbon dioxide emissions moving around the planet. The visualization is driven by massive climate data sets and highly detailed emissions maps created by NASA researchers and external partners. The resulting visualization shows the impact of power plants, fires, and cities, and how their emissions are spread across the planet by weather patterns and airflow.
      “Both policymakers and scientists try to account for where carbon comes from and how that impacts the planet,” said NASA Goddard climate scientist Lesley Ott, whose research was used to generate the final visualization. “You see here how everything is interconnected by the different weather patterns.”
      By combining visual storytelling with supercomputing power, the SVS team continues their work to captivate and connect with audiences while educating them on NASA’s scientific research and efforts.
      The NASA Center for Climate Simulation is part of the NASA High-End Computing Program, which also includes the NASA Advanced Supercomputing Facility at Ames Research Center in California’s Silicon Valley.

      The Aerostar Thunderhead balloon carries the STRATO payload into the sky to reach the stratosphere for flight testing. The balloon appears deflated because it will expand as it rises to higher altitudes where pressures are lower.Credit: Colorado Division of Fire Prevention and Control Center of Excellence for Advanced Technology Aerial Firefighting/Austin Buttlar NASA is participating in a collaborative effort to use high-altitude balloons to improve real-time communications among firefighters battling wildland fires.  
      The rugged and often remote locations where wildland fires burn mean cell phone service is often limited, making communication between firefighters and command posts difficult.  
      The flight testing of the Strategic Tactical Radio and Tactical Overwatch (STRATO) technology brought together experts from NASA’s Ames Research Center in California’s Silicon Valley, the U.S. Forest Service, high-altitude balloon company Aerostar, and Motorola to provide cell service from above. The effort was funded by the NASA Science Mission Directorate’s Earth Science Division Airborne Science Program and the agency’s Space Technology Mission Directorate Flight Opportunities program.  
      “This project leverages NASA expertise to address real problems,” said Don Sullivan, principal investigator for STRATO at NASA Ames. “We do a lot of experimental, forward-thinking work, but this is something that is operational and can make an immediate impact.” 
      Flying High Above Wildland Fires 
      Soaring above Earth at altitudes of 50,000 feet or more, Aerostar’s Thunderhead high-altitude balloon systems can stay in operation for several months and can be directed to “station keep,” staying within a radius of few miles. Because wildland fires often burn in remote, rugged areas, firefighting takes place in areas where cell service is not ideal. Providing cellular communication from above, from a vehicle that can move as the fire changes, would improve firefighter safety and firefighting efficiency. 
      The STRATO project’s first test flight took place over the West Mountain Complex fires in Idaho in August and demonstrated significant opportunities to support future firefighting efforts. The balloon was fitted with a cellular LTE transmitter and visual and infrared cameras. To transmit between the balloon’s cell equipment and the wildland fire incident command post, the team used a SpaceX Starlink internet satellite device and Silvus broadband wireless system. 
      When tested, the onboard instruments provided cell coverage for a 20-mile radius. By placing the transmitter on a gimbal, that cell service coverage could be adjusted as ground crews moved through the region. 
      The onboard cameras gave fire managers and firefighters on the ground a bird’s-eye view of the fires as they spread and moved, opening the door to increased situational awareness and advanced tracking of firefighting crews. On the ground, teams use an app called Tactical Awareness Kit (TAK) to identify the locations of crew and equipment. Connecting the STRATO equipment to TAK provides real-time location information that can help crews pinpoint how the fire moves and where to direct resources while staying in constant communication. 
      Soaring Into the Future 
      The next steps for the STRATO team are to use the August flight test results to prepare for future fire seasons. The team plans to optimize balloon locations as a constellation to maximize coverage and anticipate airflow changes in the stratosphere where the balloons fly. By placing balloons in strategic locations along the airflow path, they can act as replacements to one another as they are carried by airflow streams. The team may also adapt the scientific equipment aboard the balloons to support other wildland fire initiatives at NASA. 
      As the team prepares for further testing next year, the goal is to keep firefighters informed and in constant communication with each other and their command posts to improve the safety and efficiency of fighting wildland fires. 
      “Firefighters work incredibly hard saving lives and property over long days of work,” said Sullivan. “I feel honored to be able to do what we can to make their jobs safer and better.”

      Coastal locations, such as Drakes Bay on the Point Reyes peninsula in Northern California, are increasingly vulnerable to sea level rise.NOAA/NMFS/WCR/CCO The information will help people who live in coastal areas prepare for impacts caused by rising sea levels.
      Earth’s ocean is rising, disrupting livelihoods and infrastructure in coastal communities around the world. Agencies and organizations are working to prepare people as their world changes around them, and NASA information is helping these efforts.
      The agency’s global data is now available in the sea level section of the Earth Information Center. NASA developed the global sea level change website in collaboration with the U.S. Department of Defense, the World Bank, the U.S. Department of State, and the United Nations Development Programme.  
      The site includes information on projected sea level rise through the year 2150 for coastlines around the world, as well as estimates of how much flooding a coastal community or region can expect to see in the next 30 years. The projections come from data collected by NASA and its partners and from computer models of ice sheets and the ocean, as well as the latest sea level assessment from the Intergovernmental Panel on Climate Change, and other sources.
      “NASA innovates for the benefit of humanity. Our cutting-edge instruments and data-driven information tools help communities and organizations respond to natural hazards and extreme weather, and inform critical coastal infrastructure planning decisions,” said Karen St. Germain, director of the Earth science division at NASA Headquarters in Washington.
      Information to Action
      International organizations such as the World Bank will use the data from the global sea level change site for tasks including the creation of Climate Risk Profiles for countries especially vulnerable to sea level rise.
      The Defense Department will continue to incorporate sea level rise data into its plans to anticipate and respond to hazards posed to its facilities by the effects of rising oceans. Similarly, the State Department uses the information for activities ranging from disaster preparedness to long-term adaptation planning to supporting partners around the world in related efforts.
      “We are at a moment of truth in our fight against the climate crisis. The science is unequivocal and must serve as the bedrock upon which decision-making is built. With many communities around the world already facing severe impacts from sea-level rise, this new resource provides a vital tool to help them protect lives and livelihoods. It also illustrates what is at stake between a 1.5-degree-Celsius world and a current-policies trajectory for all coastal communities worldwide,” said Assistant Secretary-General Selwin Hart, special adviser to the United Nations secretary-general on climate action and just transition.
      Rising Faster
      NASA-led data analyses have revealed that between 1970 and 2023, 96% of countries with coastlines have experienced sea level rise. The rate of that global rise has also accelerated, more than doubling from 0.08 inches (0.21 centimeters) per year in 1993 to about 0.18 inches (0.45 centimeters) per year in 2023.
      As the rate of sea level rise increases, millions of people could face the related effects sooner than previously projected, including larger storm surges, more saltwater intrusion into groundwater, and additional high-tide flood days — also known as nuisance floods or sunny day floods.
      “This new platform shows the timing of future floods and the magnitude of rising waters in all coastal countries worldwide, connecting science and physics to impacts on people’s livelihoods and safety,” said Nadya Vinogradova Shiffer, director of the ocean physics program at NASA Headquarters in Washington.
      Data released earlier this year found that Pacific Island nations will experience at least 6 inches (15 centimeters) of sea level rise in the next 30 years. The number of high-tide flood days will increase by an order of magnitude for nearly all Pacific Island nations by the 2050s.
      “The data is clear: Sea levels are rising around the world, and they’re rising faster and faster,” said Ben Hamlington, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and head of the agency’s sea level change science team. “Having the best information to make decisions about how to plan for rising seas is more crucial than ever.”
