The after-effects of one other winter storm are seen on this NOAA-20 satellite picture. It exhibits a swath of snowfall left by the storm throughout the midwestern United States.
Though the black and white rendering might not be as instantly charming as a colourful, art-like, remote-sensing picture, for me it is simply as dazzling. That is as a result of the satellite was in a position to see the swath of snow at night time, with simply the faint illumination of moonlight to disclose its presence — from 22,000 miles (35,000 km) away.
Seeing within the night time from space is made potential by a special sensor aboard the NOAA-20 satellite known as the “Day/Night time Band.” It is designed to seize comparatively faint gentle from pure and synthetic sources, comparable to metropolis lights, ships, fires, flaring from power operations, and lightning — in addition to options illuminated by moonlight.
Within the picture, the winter storm monitor, as revealed by the swath of snow, culminates within the glowing metropolitan space of Chicago alongside Lake Michigan. Lights from different cities, and roads linking them, additionally stand out, as do lake-effect clouds over the Nice Lakes.
This picture was initially revealed by the CIMSS Satellite tv for pc Weblog, as a part of their very own 2022 highlights submit. Click on here to see all of these marvelous photos. Over time, they’ve graciously let me use a lot of their satellite photos and animations, and I am very grateful for that.
Within the subsequent installment of this two-part collection, I will embrace one other instance of dramatic nighttime imagery made potential by the Day/Night time Band sensor, together with extra “eARTh,” and imagery that includes an erupting volcano, wildfire, and proof of drought within the southwestern United States.
