Smoke from ongoing wildfires in the Pacific NW pushed daily-average PM2.5 air quality above the US health standard on 28 Sep in northern ID, southwestern OR & central-northern WA, per @AIRNow regulatory monitors & estimated by VIIRS on @JPSSProgram satellites. @NOAASatellites
Thick smoke (purple shading) from wildfires in Washington State blew northward into British Columbia, Canada yesterday 23 Sep, observed by the @JPSSProgram VIIRS sensor on @NOAASatellites NOAA-21.
Yesterday marked the #AutumnEquinox. See how greenery across the United States changed from June through mid-September 2025, as the seasons shift from summer to fall. 🌳🍂
Wildfire smoke from British Columbia, Canada, is seen in this observation from the #VIIRS instrument onboard the #NOAA20 satellite on Sept. 17, 2025. Several fires are highlighted as red dots, with smoke drifting northeast across the northwestern U.S. and southwestern Canada.
Wildfires in northwestern Washington State and southern British Columbia emitted thick smoke (purple shading) that reached into western Alberta yesterday 17 Sep, detected by the @JPSSProgram VIIRS sensor on @NOAASatellites NOAA-20. @Karma_lobsang12
As they passed over North America, @NOAA's @JPSSProgram satellites captured the brilliance of the #NorthernLights on Sept. 14-15. Learn more: bit.ly/46sWZQd #AuroraBorealis
The @JPSSProgram VIIRS sensor on @NOAASatellites NOAA-21 detected a plume of thick Saharan dust (brown shading) blowing off the coast of West Africa & over the Atlantic Ocean yesterday 16 Sep. @Karma_lobsang12
It's #WhereInTheWorld Wednesday! 🎉 Yesterday, the #NOAA21 🛰️ captured a clear view of a broad, tan-colored river basin in the Pacific Northwest.
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).
