Here are the corresponding 1-minute #GOESEast Infrared images. cimss.ssec.wisc.edu/satellite-bl...
Deerocrat and Rabbpublican actually agreeing on something in our front yard this evening.
1-minute #GOESWest GeoColor RGB images with an overlay of Next Generation Fire System polygons showed the rapid spread of the #OldTrailsFire, which was forcing evacuations in parts of the Spokane area. More on the CIMSS Satellite Blog: cimss.ssec.wisc.edu/satellite-bl... #WAwx
In a before/after (13 July vs 29 July) comparison of Landsat-8 "Natural Color RGB" images, a faint signature of the EF3-rated tornado damage path could be seen in the Menasha WI area (a transition from green shades to tan shades, due to tree/vegetation damage). #WIwx
Update: feels like 114.3 F in my back yard. Might wear shorts today.
1-minute @noaa.gov #GOESEast (GOES-19) Visible images revealed mesovortices within the eye of #Genevieve as it was rapidly intensifying to a Category 4 hurricane in the East Pacific. GLM Flash Points showed intermittent lightning activity within the eyewall.
Here are the corresponding 1-minute Visible images leading up to sunset.
1-minute GOES-18 True Color RGB images showing the hazy plume of resuspended volcanic ash (from the 1912 eruption of Novarupta-Katmai) that was being lofted from the surface by strong NW winds and carried toward Kodiak Island. #AKwx
"Rapid scan" satellite imagery from this event was available every 5-10 minutes -- which isn't quite as impressive as the 1-minute (or 30-second) GOES imagery often available today. cimss.ssec.wisc.edu/satellite-bl...
The best part about GOES-19 not sending data all morning is that I didn't have to see how bad the wildfire smoke looks -- but now that data is flowing again, omFUg...
2.5-minute Himawari-9 Visible and Infrared images showing the eyewall of Super Typhoon #Bavi affecting the island of Rota. Animation will periodically update at cimss.ssec.wisc.edu/satellite-bl...
Nighttime NOAA-20 (mislabeled as NPP) VIIRS Day/Night Band image valid at 1525 UTC on 05 July, showing the large eye of Super Typhoon #Bavi as it was approaching the island of Rota. "Side-lighting" by the Moon was brightly illuminating the western eyewall.
2.5-minute Himawari-9 Infrared images show that the eye of 155-knot Category 5 Super Typhoon #Bavi is on track to pass very near the island of Rota, between Saipan and Guam.
