It’s officially autumn in the Northern Hemisphere—the season when days get shorter as that half of the world heads toward winter. Meanwhile in the Southern Hemisphere, spring has begun!
On Sept. 15, 2020, the VIIRS instrument onboard the NOAA-20 satellite captured this Day/Night Band image of the Gulf Coast at 3:43 a.m. EDT. This type of imagery shows us nighttime views of clouds as well as various types of nocturnal lights, which allow us to study geophysical and socio-economic activities. This panchromatic channel covers wavelengths from 0.5 to 0.9 μm, and is capable of observing the Earth in the visible/near-infrared spectral range.
On September 1, 2020, the Himawari-8 satellite, which is operated by Japan Meteorological Agency, viewed Typhoon Maysak spinning near the southern islands of Japan.
The Advanced Baseline Imager (ABI) onboard NOAA’s GOES-R series of geostationary satellites utilizes 16 different wavelengths (or spectral bands) to monitor the Earth in different ways. These satellites also stay more than 22,000 miles above specific areas of the planet as it rotates, so they can see how weather patterns change over time.
On August 10, 2020, NOAA’s GOES-East satellite tracked severe thunderstorms as they raced across much of the Midwest and caused a widespread, fast-moving windstorm called a derecho. According to the National Weather Service's Storm Prediction Center, the derecho traveled from far southeastern South Dakota into Ohio—a distance of about 770 miles—in a span of 14 hours.
As NOAA’s satellites focused in on South America on Aug. 7, 2020, they could see smoke plumes from various fires across the continent, spanning from the Amazon rainforest to the central and southern lowland regions.
A lot is happening in this dynamic shot of the Atlantic, which was captured by the GOES-East satellite today, July 31, 2020. This imagery utilizes the satellite’s Dust RGB product to show the dust (light pink) that is continuing to blow westward over the Atlantic Ocean from the Sahara Desert. We can also see Hurricane Isaias swirling over the Caribbean Sea.
On July 23, 2020, NOAA’s GOES-West satellite captured this impressive view of the eye of Hurricane Douglas as it spun over the Pacific Ocean. The first hurricane of the 2020 eastern Pacific season, the storm rapidly intensified on Thursday and had a maximum sustained wind speed of 120 mph at the last report, making it a major Category-3 storm on the Saffir-Simpson Hurricane Wind Scale.
