Climate Change

JPSS satellites also take the temperature of our lower and upper atmosphere. By contributing to a long-term archive of these temperature measurements, they show us how our planet’s atmosphere has changed over time.

And they collect data on ozone that continues five decades of records. These measurements are used by ozone-assessment researchers and policy makers to create global climate models and monitor global ozone concentrations.

Image of wildfires over the westcoast in California.

California Wildfires

The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument captures natural-color images of fires, like the massive Dixie fire seen here, the second largest in the state’s history. Scientists also use VIIRS data to detect and map fires in remote places like Alaska, where remote-sensing airplanes don’t fly.  

VIIRS also contributes measurements to a model called HRRR-Smoke, which simulates the behavior of wildfire smoke–its thickness and movement, both high above the clouds and on the ground. At the surface, fine smoke particles can penetrate deep into the lungs and aggravate a range of health problems, such as asthma and heart and lung disease. Smoke high in the atmosphere can also affect visibility for pilots and block incoming sunlight.

Image of Hurricane Ida

Hurricane Ida

On August 29, 2021, Hurricane Ida made landfall near Port Fourchon, Louisiana, as a strong Category-4 storm–exactly 16 years after Hurricane Katrina struck the area. Ida brought with it torrential rainfall, flooding and sustained winds as high as 150 mph that tore off roofs, downed trees, damaged whole neighborhoods and snuffed out power to more than a million homes. As it approached landfall. Ida’s wind speed, fueled by unusually warm ocean temperatures, atmospheric moisture, and low wind shear, increased by 65 mph in 24 hours. Its remnants then swept northeast, where it caused devastating flooding in New Jersey, New York, Pennsylvania and Connecticut and led to nearly four dozen confirmed deaths. 

The Advanced Technology Microwave Sounding (ATMS) instrument took measurements that provided early warning of this storm. By measuring atmospheric temperature and moisture, as well as sea surface temperatures, ATMS gives forecasters data they need to predict how a hurricane will track, along with its intensity. These data are combined with ground-based observations and weather models, and they help people make important decisions on whether they need to take shelter or evacuate.

Drought And Heat Waves In The American West

The drought that has gripped the American West since 2000 is the worst the region has seen in at least 1,200 years, according to a recent study in the journal Nature Climate Change. 

A product from the VIIRS instrument called the Vegetation Health Index shows vegetation and crop health, represented in color coded maps, like the one seen here. Green and blue indicates lush, healthy growth; red means parched and dry.   

This product informs the U.S. Drought Monitor map, which plays an important role in decision-making involving agricultural reimbursements and other government assistance. It is also used regularly by meteorologists at the U.S. Department of Agriculture to monitor global crop growth.

Image of the Hunga Tonga-Hunga volcanic eruption.

Hunga Tonga-Hunga Ha-Apai Volcanic Eruption

When the Hunga Tonga-Hunga Ha’apai volcano massively erupted on Jan. 11, 2o22, it unleashed a plume of ash and smoke that spewed more than 20 miles into the atmosphere, sent a shockwave around the world and triggered a tsunami that devastated parts of the Pacific island nation of Tonga. 

As JPSS satellites passed over the volcano, their Ozone Mapping and Profiler Suite (OMPS) instruments measured sulfur dioxide emissions in the plume spewing from the eruption. The volcanic plume contains particles made of glassy silicate ash and sulfuric acid droplets, as well as gases, both of which are health hazards in high concentrations. 

Volcanic clouds can pose threats to aircraft by affecting cabin air quality, damaging the airframe and engines, and reducing visibility.

This map shows a stratospheric sulfur dioxide cloud over the Pacific Ocean from January 15, 2022 eruption of Hunga Tonga – Hunga Ha’apai underwater volcano (triangle) near the Pacific Island Nation of Tonga. These measurements were collected on January 17, 2022 by the OMPS instrument on the Suomi-NPP satellite.

Climate Change

The ATMS instrument on JPSS takes measurements of the Earth’s atmosphere and contributes this data to an archive that shows us how the atmosphere has changed over time. 

Temperature measurements captured by ATMS and other microwave sounders show us that the troposphere, the lowest layer of the Earth’s atmosphere is warming by .15 degrees Celsius per decade, and .62 degrees over the past 42 years since the first sounder was launched, according to data from NOAA’s Center for Satellite Applications and Research. And that rate is increasing. From August 2002 to December 2020, the warming rate had climbed to an average of .23 degrees Celsius per decade. The warming is caused by greenhouse gases, which act as a blanket, trapping heat in the troposphere.  

Meanwhile, in the stratosphere, temperatures are cooling. This is because increasing carbon dioxide in the stratosphere emits more radiation to outer space, causing net energy loss there. Both the warming in the troposphere and the cooling in the stratosphere are indicators of climate change.

Giant Iceberg Breaks Off Antarctica 

Western Side Of Ronne Ice Shelf

In May 2021, an iceberg nearly the size of Delaware sheared off from the edge of Antarctica and floated into the Weddell Sea, where it fractured into pieces. The iceberg, named A-76 by the U.S. National Ice Center, measured 1,668 square miles before breaking up. 

The VIIRS instrument on the JPSS satellites observed A-76 splitting from the Ronne Ice Shelf on May 15 and 16 during multiple flyovers.

VIIRS can see ice sheets, ice shelves and icebergs, such as A-76, at a high spatial resolution of 375 meters, and the instrument's wide swath and frequent overpasses at the poles resulted in good coverage of this calving event. 

VIIRS also plays an important role in mapping and monitoring glaciers, along with measuring the surface albedo and temperature of ice sheets and the ice concentration, thickness, surface temperature and motion of sea ice.

Phytoplankton Bloom

Barents Sea

The JPSS satellite’s VIIRS instrument captures vibrant blue and turquoise swirls, indicating a phytoplankton bloom north of Finland. Phytoplanktons are tiny, microscopic plants that form at the base of food webs in marine ecosystems and thrive in Arctic waters. They are common in this location in late July and August, thanks to a combination of 24-hour sunlight, minimal ice cover and relatively warm surface waters. This image is from the Suomi-NPP satellite.

Saharan Dust Storm

Northwest Africa

For several days in February and March 2022, strong winds from the Sahara Desert carried sand and dust east off the coast of Africa, over the Atlantic Ocean and north toward Europe. The Saharan Air Layer, a mass of dry, dusty air that forms over the desert and extends as high as 20,000 feet into the atmosphere, can travel several thousand miles, grounding flights, turning the sky orange and suppressing cyclone development during hurricane season, but also bringing minerals that replenish soil nutrients as far away as the Amazon Rainforest. 

The JPSS satellites’ OMPS instruments measure aerosols from the dust plumes, monitoring air quality and visibility for aircraft. 

Image of clouds

Cloud Formations  

Guadalupe Island

The JPSS satellite’s VIIRS instrument captures interesting cloud formations, like these von Karman vortices over Guadalupe Island, off the west coast of Mexico’s Baja California. These are caused by mountaintops, volcanoes or islands that disrupt the flow of wind, causing air and clouds to rotate into a spiral, similar to the way boulders create downstream eddies in rivers. Windspeed determines the shape of the clouds.

Image of Hurricane Ian

Hurricane Ian 

Cayo Costa, Florida 

Hurricane Ian, one of the most powerful storms ever recorded in the United States, made landfall to the west of Ft. Myers, Fla., on Sept. 28 as a Category 4 hurricane after causing widespread damage in western Cuba. In Florida, the storm destroyed entire coastal communities and unleashed a dangerous storm surge before moving up the coast, where it made a second landfall in South Carolina on Sept. 30. The storm was responsible for more than 120 deaths, according to state and county officials. 

This image, captured by the NOAA-20 satellite on Sept. 27, shows the massive, well-organized storm approaching Florida’s coast.

More Data, More Often

Satellites travel fast, but the amount of time it takes to circle the planet is too long to wait to get important weather data into people’s hands. 

That’s why there are two primary ground stations that collect data from JPSS satellites. One is located near the North Pole, on Norway’s remote Svalbard Islands. The other is at the McMurdo Station in Antarctica. Secondary sites that serve as backups are located in Fairbanks, Alaska; White Sands, New Mexico; and Troll, Antarctica.

Who Uses The Data?

These people all rely on JPSS data to tackle weather and climate concerns:

Meteorologists
Meteorologists use ATMS and CrIS data to forecast weather and extreme storms. In fact, sounding data makes up the largest data source in these models. These data have improved the accuracy of weather forecasts and hurricane tracking since Suomi-NPP began flying in 2011.
First Responders
Emergency responders use JPSS images that show power outages after hurricanes, earthquakes and other weather disasters from the VIIRS instrument’s Day Night Band. They also use data on fires, floods and general weather forecasts when planning a response.
Pilots
In some clouds, supercooled droplets turn to ice and accumulate on the windshield, nose, propeller and wings of planes, changing the weight of the aircraft. Pilots use a VIIRS cloud product to detect these icy cloud conditions on flight routes and determine flight safety.
Volcano Scientists
Volcano scientists use OMPS data to map volcanic clouds and measure sulfur dioxide emissions. Volcanic Ash Advisory centers use these maps to predict the cloud’s movement and to reroute aircraft, if necessary.
Fire Crews
The first moments after a fire ignites are critical to containing it, and VIIRS can detect and monitor day and nighttime fires. This is especially useful in remote areas like the Alaskan wilderness where remote sensing airplanes don’t fly.
Climate Scientists
Climate scientists use ATMS and other microwave sounding data to track and model atmospheric temperature changes over time. This data also adds to a record that dates back 40 years.
Football Coaches
Football coaches have used JPSS data to monitor the effect of wildfire smoke on outdoor air quality and have canceled Friday night football games based on these measurements.
Ship Commanders
Ship commanders and captains use weather models fed by JPSS data to track thunderstorms, squalls and other tropical storms and hurricanes, and will often make decisions to divert or suspend operations based on these data.

How JPSS Fits Into The Fleet

JPSS-2 launched from the Vandenberg Space Force Base in Lompoc, California on November 10, 2022. 

JPSS-2 is part of a long history of NOAA and NASA satellites that date back to 1960, when the first weather satellite, TIROS-1 launched from Cape Canaveral in Florida.  And it will be followed by two more nearly identical satellites, JPSS-3 and JPSS-4.  This means we’ll likely have data from these satellites until the late 2030s.
