Thick wildfire smoke swirls around a low over the Pacific Northwest.

Congratulations to CIRES/@NOAAGSL's Jeffrey Duda for winning a 2025 Andy Schwarz Editor's Award! Duda will receive his award at the 105th AMS Annual Meeting in January. ametsoc.org/index.cfm/ams/…

Tomorrow, Sept 4, at 12 pm AKDT, join Sealaska Heritage Institute for lecture on archaeology, & role of Indigenous knowledge & advanced robotic tech in exploring Southeast Alaska’s submerged caves. Watch live: youtube.com/@SealaskaHerit… About the project: oceanexplorer.noaa.gov/explorations/2…

A new study finds wildfire smoke significantly raised fine particulate matter and ozone levels, leading to numerous days when air pollution exceeded health standards. climate.gov/news-features/…

ICESat-2 is the third in a series of NASA missions designed to provide continuous polar observations over time. Previous missions include the ICESat/GLAS mission followed by Operation IceBridge. The NSIDC DAAC provides data from all 3 missions. Get data: nsidc.org/data/icesat-2

Arctic sea ice extent for August 2024 averaged 5.21 million square kilometers (2.01 million square miles), the 4th lowest in the 46-year passive microwave satellite record. Learn more in our latest Sea Ice Today analysis: nsidc.org/sea-ice-today/…

.NOAA's #GOESEast 🛰️ captured #GeoColor imagery of thick #wildfire #smoke over South America today. In another view, aerosol optical depth (AOD) imagery shows how the smoke can block sunlight, with maroon indicating very hazy conditions.

On this day in 1877, CU Boulder 🦬 opened its door to students for the first time. Learn more about CU Boulder's history: colorado.edu/about/history/…

A new study finds that combining data from both the ocean and atmosphere can lead to more accurate forecasts, even in complex environments like the Red Sea. climate.gov/news-features/…
