This satellite picture of Lapland integrates 3 radar acquisitions from the Copernicus Sentinel-1 objective to reveal modifications in land conditions with time. The very first image from February 28, 2019, is connected with green, the 2nd from March 11, 2019, is connected to red, and the 3rd from April 4, 2019, portrays modifications in blue.

The Copernicus Sentinel-1 objective takes us over Lapland, the biggest and northern most area of Finland, in the nick of time for Christmas.
Located within the Arctic Circle, Lapland, likewise called Sápmi by the Sami individuals, extends throughout northern Norway, Sweden and Finland, and into the Kola Peninsula of Russia. It is bound by the Norwegian Sea on the west, the Barents Sea on the north, and the White Sea to the east.
Lapland throughout the cold weather suggests snowfall, temperature levels well listed below no degrees and the Northern Lights, or the Aurora Borealis, lighting up the dark, night skies. Rovaniemi, the capital of Lapland, lies at the top of the image, and is thought about the main home town of Santa Claus.
In Rovaniemi, the Arctic Circle goes through Santa Claus Village, situated 8 kilometers north of the town hall. The Arctic Circle marks the southernmost latitude where the sun can remain constantly listed below or above the horizon for 24 hours – these phenomena are called the Midnight Sun in the summertime and the Polar Night in the winter season.
This image integrates 3 radar acquisitions from the Copernicus Sentinel-1 objective to reveal modifications in land conditions with time. The very first image from February 28, 2019, is connected with green, the 2nd from March 11, 2019, is connected to red, and the 3rd from April 4, 2019, portrays modifications in blue.
The modifications that happened with time in this image are mostly seen in the bottom-left of the image, where sea ice in the Gulf of Bothnia has actually moved significantly along the coast. The Gulf of Bothnia, the northern most arm of the Baltic Sea, is located in between Finland’s west coast and Sweden’s east coast. As it gets the water of a lot of rivers, consisting of the Torne and Kemijoki rivers noticeable in the image, its salinity is incredibly low, and ice cover is kept for approximately 5 months throughout the winter season.
There are lots of little islands, making navigation in the gulf hard. For this factor, vessels taking a trip in the gulf get icebreaker support on their journey in the ice-covered waters, and follow the straight lines relieving their navigation. Straight lines can be seen originating from the Port of Röyttä and the Port of Ajos.
As an innovative radar objective, Copernicus Sentinel-1 can image the surface area of Earth through cloud and rain and despite whether it is day or night – making it a perfect objective to keep an eye on locations frequently shrouded in darkness like the polar areas.
