Scientists believe that the new NOAA-21 satellite will provide important information about our planet's oceans, land and atmosphere.

NASA's new space satellite, called NOAA-21, was launched last November. This spacecraft is the second of four such meteorological satellites, which are united by the Joint Polar Satellite System project. It was the cameras of this satellite that made a stunning global image of the Earth, which, in particular, shows the waters of the Caribbean Sea and smog in northern India, writes the Daily Mail.

The new NOAA-21 satellite has already begun active work in near-Earth orbit, and scientists have high hopes for it, because it will provide important information about the oceans, land and atmosphere of our planet. Now, thanks to his pictures, you can see what the whole Earth looks like from space.
But besides the fact that the spacecraft will continue to show all the features of our planet from space, it will monitor the ecology of the ocean, and will also be able to track forest fires, droughts and floods on land.
Back in early December last year, NOAA-21, using its main instrument called VIIRS, began taking detailed images of the planet, from which scientists compiled a complete picture of the processes taking place on Earth. This satellite can take images in both visible and infrared light spectra, allowing scientists to see all the details on the Earth's surface.
For example, NASA showed how the snow-covered Himalayas and the Tibetan plateau look, as well as in the frame hit the smog that hangs in the air over northern India, which is caused by burning crops.
Among the brightest satellite images, the scientists also highlighted a stunning view of the waters of the Caribbean Sea, and Cuba and the Bahamas are visible in this image.
The VIIRS instrument measures sea surface temperature, an indicator that is important to monitor the formation of hurricanes, and ocean color monitoring helps monitor phytoplankton activity, which is a key indicator of ocean ecology and the health of the marine environment.
On land, the VIIRS can detect and measure the severity of wildfires, droughts and floods, and its data can be used to track the thickness and movement of smoke from wildfires. The instrument also provides accurate analysis of snow and ice cover, clouds, fog, aerosols and dust in the air. Also, the satellite can see in detail the appearance of lightning and auroras.
