This #NOAA21 satellite view from Oct. 9, 2024 shows Hurricane Milton near Cuba. Twenty years after Hurricane Katrina, JPSS instruments represent significant advancements, providing forecasters with critical data to track and predict storms. More in this #EarthFromOrbit video:…
Twenty years ago, @NOAA satellites helped monitor and track one of the deadliest hurricanes in U.S. history—#HurricaneKatrina—as it devastated New Orleans and the Mississippi coast. Today, NOAA's latest generation of satellites provide faster and more accurate forecasts and…
Numerous wildfires in the western US continued burning on 26 Aug, observed by @JPSSProgram VIIRS on @NOAASatellites NOAA-20. Fire radiative power (FRP, Left) shows the fires' location & intensity, and aerosol detection (Right) indicates the fires released thick smoke (purple).
It's #WhereInTheWorld Wednesday! On August 11, 2025, #NOAA21 captured this sapphire of a freshwater lake, known as the "Caribbean of the Rockies" due to its unique color caused by limestone deposits. It's over 250,000 years old and formed by tectonic activity.
Aerosol optical depth (AOD) from @JPSSProgram VIIRS on @NOAASatellites NOAA-21 observed thick smoke (dark red shading, AOD ≥1) across the Western US on 23 Aug from numerous wildfires, particularly in Idaho, Montana & Wyoming. @Weather_West

On August 17, 2025, the #NOAA21 satellite’s VIIRS instrument observed Hurricane #Erin swirling over the Caribbean, capturing information that helps forecasters track the storm’s development. Check out the latest #EarthFromOrbit video for more: nesdis.noaa.gov/news/category-…
#hurricaneErin became the Atlantic’s first #hurricane of the season and strengthened into a Category 5 storm just one day later—one of the fastest intensifications on record. Learn how @NOAA satellites monitored and tracked #Erin in this week's #EarthFromOrbit video:…
Smoke from the Island Creek wildfire in Idaho degraded daily PM2.5 air quality yesterday 21 Aug, with Unhealthy (Code Red) near the fire & Moderate (Code Yellow) further downwind; observed by @AIRNow regulatory monitors (dots) & estimated from @JPSSProgram VIIRS (shading).
Hurricane Erin, the first Atlantic hurricane in the 2025 season, rapidly intensified from a Category 1 to a Category 5 storm in just over 24 hours. These Suomi NPP satellite images show Erin’s path from August 14-19. go.nasa.gov/4mTq0uO
This #BackToSchool season, get creative with a hands-on project by making your own mini booklet, or zine, to explore the water cycle, and learn how JPSS satellites monitor the movement of Earth’s water from space. 💧 For more: nesdis.noaa.gov/about/k-12-edu…
Aerosol optical depth from @JPSSProgram VIIRS on @NOAASatellites NOAA-21 observed smoke (red/orange/yellow/teal shading, AOD ≥0.5) across the Iberian Peninsula today 21 Aug from the ongoing wildfires in Portugal & Spain.
Low Earth Orbit (LEO) satellites like JPSS satellites equipped with #VIIRS, provide steady coverage of Alaska’s high-latitude regions, vital for monitoring remote Arctic waters and supporting the communities that depend on them. For more: nesdis.noaa.gov/news/space-sea…
It's #WhereInTheWorld Wednesday! On August 2, 2025, #NOAA20 captured this freshwater lake, which means "big water" in the Seminole Indian language. The bright color of the lake in this image is caused by a phenomenon called “sun glint”—sunlight reflecting off water at the same…
Transported smoke from Canadian wildfires caused Code Red (Unhealthy) and Orange (USG) daily PM2.5 air quality in MN, ND & SD yesterday 11 Aug. @JPSSProgram satellite-estimated PM2.5 (shading) fills gaps in the @AIRNow regulatory monitor network (dots). @MnPCA @NOAASatellites
It's #WhereInTheWorld Wednesday! 🥳 On August 1, 2025, #NOAA21 captured this bay in Alaska that is fed by 2 rivers. At low tide, extensive intertidal habitat is exposed, which supports thousands of shorebirds. The birds use the peninsula’s lagoons to replenish energy reserves…
Aerosol detection from VIIRS on @JPSSProgram NOAA-20 highlights the enormous extent of wildfire smoke (lavender/pink shading) over central Canada & eastern US on 5 Aug, as well as smaller plumes from wildfires in the western US, e.g. Colorado. @NOAASatellites
It's #WhereInTheWorld Wednesday! 🥳 On July 21, 2025, #NOAA21 captured a clear view of this national park, known for its rugged terrain, striking geological formations, and rich fossil beds. It also boasts the largest expanse of mixed-grass prairie in the United States.
Hurricane Iona and Tropical Storm Keli travel westward in the central Pacific. Seen by multiple polar-orbiting satellites during the past 24-hours.
