What happens in the Arctic doesn’t stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth’s rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost part of Earth have a large impact on the entire planet. That’s because the Arctic region acts like Earth’s air conditioner.  

Much of the Sun’s energy is transported from tropical regions of our planet by winds and weather systems into the Arctic where it is then lost to space. This process helps cool the planet.  

The NASA-sponsored Arctic Radiation Cloud Aerosol Surface Interaction Experiment (ARCSIX) mission is flying three aircraft over the Arctic Ocean north of Greenland to study these processes. The aircraft are equipped with instruments to gather observations of surface sea ice, clouds, and aerosol particles, which affect the Arctic energy budget and cloud properties. The energy budget is the balance between the energy that Earth receives from the Sun and the energy the Earth loses to outer space.

“More sea ice makes that air conditioning effect more efficient. Less sea ice lessens the Arctic’s cooling effect,” says Patrick Taylor, a climate scientist at NASA’s Langley Research Center in Hampton, Virginia. “Over the last 40 years, The Arctic has lost a significant amount of sea ice making the Arctic warm faster. As the Arctic warms and sea ice melts, it can cause ripple effects that impact weather conditions thousands of miles away, how fast our seas are rising, and how much flooding we get in our neighborhoods.”

The first series of flights took place in May and June as the seasonal melting of ice started. Flights began again on July 24 during the summer season, when sea ice melting is at its most intense. 

“We can’t do this kind of Arctic science without having two campaigns,” said Taylor, the deputy science lead for ARCSIX. “The sea ice surface in the spring was very bright white and snow covered. We saw some breaks in the ice. What we will see in the second campaign is less sea ice and sea ice that is bare, with no snow. It will be covered with all kinds of melt ponds – pooling water on top of the ice – that changes the way the ice interacts with sunlight and potentially changes how the ice interacts with the atmosphere and clouds above.” 

Sea ice and the snow on top of the ice insulate the ocean from the atmosphere, reflecting the Sun’s radiation back towards space, and helping to cool the planet. Less sea ice and darker surfaces result in more of the Sun’s radiation being absorbed at the surface or trapped between the surface and the clouds.

Understanding this relationship, and the role clouds play in the system, will help scientists improve satellite data and better predict future changes in the Arctic climate.  

“This unique team of pilots, engineers, scientists, and aircraft can only be done by leveraging expertise from multiple NASA centers and our partners,” said Linette Boisvert, cryosphere lead for the mission from NASA’s Space Flight Center in Greenbelt, Maryland. “We gathered great data of the snow and ice pre-melt and at the onset of melt. I can’t wait to see the changes at the height of melt as we measure the same areas covered with melt ponds.” 

NASA partnered with the University of Colorado Boulder for the ARCSIX mission, and the research team found some surprises in their early data analysis from the spring campaign. One potential discovery is something Taylor is calling a “sea ice sandwich”, when a younger layer of sea ice is caught in between two layers of older sea ice. Scientists also found more drizzle within the clouds than expected. Both observations will need further investigating once the data is fully processed.

“A volcano erupted in Iceland, and we believe the volcanic aerosol plume was indicated by our models four days later,” Taylor said. “Common scientific knowledge tells us volcanic particles, like ash and sulfate, would have already been removed from the atmosphere. More work needs to be done, but our initial results suggest these particles might live in the atmosphere much longer than previously thought.” 

Previous studies suggest that aerosol particles in clouds can influence sea ice melt. Data collected during ARCSIX’s spring flights showed the Arctic atmosphere had several aerosol particle layers, including wildfire smoke, pollution, and dust transported from Asia and North America. 

“We got everything we hoped for and more in the first campaign,” Taylor added. “The data from this summer will help us better understand how clouds and sea ice behave. We’ll be able to use these results to improve predictive models. In the coming years, scientists will be able to better predict how to mitigate and adapt to the rapid changes in climate we’re seeing in the Arctic.”

      Using data from ESA’s SMOS satellite, scientists have revealed a surprising shift in the Southern Ocean – surface waters around Antarctica are growing saltier, even as sea ice is diminishing rapidly. This finding defies the norm because melting ice typically freshens ocean surface water.
      The implications are far-reaching as changes in this remote region can disrupt global ocean currents, affect climate patterns, and alter ecosystems far beyond the Antarctic.

      What’s Up for July? Mars shines in the evening sky, sixty years after its first close-up,
      July Planet Viewing
      Venus brightens your mornings, and the eagle soars overhead.
      First up, Mercury is visible for a brief time following sunset for the first week of July. Look for it very low in the west 30 to 45 minutes after sundown. It sets within the hour after that, so be on the ball if you want to catch it!
      Mars is visible for the first hour or two after it gets dark. You’ll find it sinking lower in the sky each day and looking a bit dimmer over the course of the month, as our two planets’ orbits carry them farther apart. The crescent Moon appears right next to Mars on the 28th.
      Sky chart showing Mercury and Mars in the western sky following sunset in early July. NASA/JPL-Caltech July is the 60th anniversary of the first successful flyby of Mars, by NASA’s Mariner 4 spacecraft in 1965. Mariner 4 sent back the first photos of another planet from deep space, along with the discovery that the Red Planet has only a very thin, cold atmosphere.
      Next, Saturn is rising late in the evening, and by dawn it’s high overhead to the south.
      Looking to the morning sky, Venus shines brightly all month. You’ll find it in the east during the couple of hours before sunrise, with the Pleiades and bright stars Aldebaran and Capella. And as the month goes on, Jupiter makes its morning sky debut,

      By the end of the month, early risers will have the two brightest planets there greeting them each morning. They’re headed for a super-close meetup in mid-August, and the pair will be a fixture of the a.m. sky through late this year. Look for them together with the crescent moon on the 21st and 22nd.
      Aquila, The Eagle
      From July and into August, is a great time to observe the constellation Aquila, the eagle.
      Sky chart showing the shape and orientation of the constellation Aquila in the July evening sky. Aquila’s brightest star, Altair, is part of the Summer Triangle star pattern. NASA/JPL-Caltech This time of year, it soars high into the sky in the first half of the night. Aquila represents the mythical eagle that was a powerful servant and messenger of the Greek god Zeus. The eagle carried his lightning bolts and was a symbol of his power as king of the gods.
      To find Aquila in the sky, start by locating its brightest star, Altair. It’s one the three bright stars in the Summer Triangle, which is super easy to pick out during summer months in the Northern Hemisphere. Altair is the second brightest of the three, and sits at the southernmost corner of the triangle.
      The other stars in Aquila aren’t as bright as Altair, which can make observing the constellation challenging if you live in an area with a lot of light pollution. It’s easier, though, if you know how the eagle is oriented on the sky. Imagine it’s flying toward the north with its wings spread wide, its right wing pointed toward Vega. If you can find Altair, and Aquila’s next brightest star, you can usually trace out the rest of the spread-eagle shape from there. ​​The second half of July is the best time of the month to observe Aquila, as the Moon doesn’t rise until later then, making it easier to pick out the constellation’s fainter stars.
      Observing the constellation Aquila makes for a worthy challenge in the July night sky. And once you’re familiar with its shape, it’s hard not to see the mythical eagle soaring overhead among the summertime stars.
      Here are the phases of the Moon for July.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA Ames research scientist Kristina Pistone monitors instrument data while onboard the Twin Otter aircraft, flying over Monterey Bay during the October 2024 deployment of the AirSHARP campaign. NASA/Samuel Leblanc In autumn 2024, California’s Monterey Bay experienced an outsized phytoplankton bloom that attracted fish, dolphins, whales, seabirds, and – for a few weeks in October – scientists. A team from NASA’s Ames Research Center in Silicon Valley, with partners at the University of California, Santa Cruz (UCSC), and the Naval Postgraduate School, spent two weeks on the California coast gathering data on the atmosphere and the ocean to verify what satellites see from above. In spring 2025, the team returned to gather data under different environmental conditions.

      Scientists call this process validation.

      Setting up the Campaign

      The PACE mission, which stands for Plankton, Aerosol, Cloud, ocean Ecosystem, was launched in February  2024 and designed to transform our understanding of ocean and atmospheric environments. Specifically, the satellite will give scientists a finely detailed look at life near the ocean surface and the composition and abundance of aerosol particles in the atmosphere.

      Whenever NASA launches a new satellite, it sends validation science teams around the world to confirm that the data from instruments in space match what traditional instruments can see at the surface. AirSHARP (Airborne aSsessment of Hyperspectral Aerosol optical depth and water-leaving Reflectance Product Performance for PACE) is one of these teams, specifically deployed to validate products from the satellite’s Ocean Color Instrument (OCI).

      The OCI spectrometer works by measuring reflected sunlight. As sunlight bounces off of the ocean’s surface, it creates specific shades of color that researchers use to determine what is in the water column below. To validate the OCI data, research teams need to confirm that measurements directly at the surface match those from the satellite. They also need to understand how the atmosphere is changing the color of the ocean as the reflected light is traveling back to the satellite.

      In October 2024 and May 2025, the AirSHARP team ran simultaneous airborne and seaborne campaigns. Going into the field during different seasons allows the team to collect data under different environmental conditions, validating as much of the instrument’s range as possible.

      Over 13 days of flights on a Twin Otter aircraft, the NASA-led team used instruments called 4STAR-B (Spectrometer for sky-scanning sun Tracking Atmospheric Research B), and the C-AIR (Coastal Airborne In-situ Radiometer) to gather data from the air. At the same time, partners from UCSC used a host of matching instruments onboard the research vessel R/V Shana Rae to gather data from the water’s surface.

      Ocean Color and Water Leaving Reflectance

      The Ocean Color Instrument measures something called water leaving reflectance, which provides information on the microscopic composition of the water column, including water molecules, phytoplankton, and particulates like sand, inorganic materials, and even bubbles. Ocean color varies based on how these materials absorb and scatter sunlight. This is especially useful for determining the abundance and types of phytoplankton.

      Photographs taken out the window of the Twin Otter aircraft during the October 2024 AirSHARP deployment showcase the variation in ocean color, which indicates different molecular composition of the water column beneath. The red color in several of these photos is due to a phytoplankton bloom – in this case a growth of red algae. NASA/Samuel Leblanc
      The AirSHARP team used radiometers with matching technology – C-AIR from the air and C-OPS (Compact Optical Profiling System) from the water – to gather water leaving reflectance data.

      “The C-AIR instrument is modified from an instrument that goes on research vessels and takes measurements of the water’s surface from very close range,” said NASA Ames research scientist Samuel LeBlanc. “The issue there is that you’re very local to one area at a time. What our team has done successfully is put it on an aircraft, which enables us to span the entire Monterey Bay.”

      The larger PACE validation team will compare OCI measurements with observations made by the sensors much closer to the ocean to ensure that they match, and make adjustments when they don’t. 

      Aerosol Interference

      One factor that can impact OCI data is the presence of manmade and natural aerosols, which interact with sunlight as it moves through the atmosphere. An aerosol refers to any solid or liquid suspended in the air, such as smoke from fires, salt from sea spray, particulates from fossil fuel emissions, desert dust, and pollen.

      Imagine a 420 mile-long tube, with the PACE satellite at one end and the ocean at the other. Everything inside the tube is what scientists refer to as the atmospheric column, and it is full of tiny particulates that interact with sunlight. Scientists quantify this aerosol interaction with a measurement called aerosol optical depth.

      “During AirSHARP, we were essentially measuring, at different wavelengths, how light is changed by the particles present in the atmosphere,” said NASA Ames research scientist Kristina Pistone. “The aerosol optical depth is a measure of light extinction, or how much light is either scattered away or absorbed by aerosol particulates.” 

      The team measured aerosol optical depth using the 4STAR-B spectrometer, which was engineered at NASA Ames and  enables scientists to identify which aerosols are present and how they interact with sunlight.

      Twin Otter Aircraft

      AirSHARP principal investigator Liane Guild walks towards a Twin Otter aircraft owned and operated by the Naval Postgraduate School. The aircraft’s ability to perform complex, low-altitude flights made it the ideal platform to fly multiple instruments over Monterey Bay during the AirSHARP campaign. NASA/Samuel Leblanc
      Flying these instruments required use of a Twin Otter plane, operated by the Naval Postgraduate School (NPS). The Twin Otter is unique for its ability to perform extremely low-altitude flights, making passes down to 100 feet above the water in clear conditions.

      “It’s an intense way to fly. At that low height, the pilots continually watch for and avoid birds, tall ships, and even wildlife like breaching whales,” said Anthony Bucholtz, director of the Airborne Research Facility at NPS.

      With the phytoplankton bloom attracting so much wildlife in a bay already full of ships, this is no small feat. “The pilots keep a close eye on the radar, and fly by hand,” Bucholtz said, “all while following careful flight plans crisscrossing Monterey Bay and performing tight spirals over the Research Vessel Shana Rae.”

      Campaign Data

      Data gathered from the 2024 phase of this campaign is available on two data archive systems. Data from the 4STAR instrument is available in the PACE data archive  and data from C-AIR is housed in the SeaBASS data archive.

      Other data from the NASA PACE Validation Science Team is available through the PACE website: https://pace.oceansciences.org/pvstdoi.htm#
      Samuel LeBlanc and Kristina Pistone are funded via the Bay Area Environmental Research Institute (BAERI), which  is a scientist-founded nonprofit focused on supporting Earth and space sciences.
