The colors of this weeks image come from the mix of 2 polarisations from the Copernicus Sentinel-1 objective which have been converted into a single image. These distinctions are noticeable in tones of blue in the image, such as the choppy Norwegian Sea, wetlands and mires such as those on the northern suggestion of Andøya and damp snow on hilltops and in mountains (bottom-right corner of the image).
Sentinel-1 is a radar mission and unlike optical video cameras, the images are white and normally black when they are gotten. By using a technology that aligns the radar beams sent and received by the instrument in one orientation– either vertically or horizontally– the resulting data can be processed in a method that produces coloured images such as the one featured here.
Although lying completely within the Arctic Circle, Lofoten experiences one of the worlds biggest elevated temperature abnormalities relative to its high latitude. Due to a convergence of the Gulf Stream with two underwater currents, the North Atlantic Current and the Norwegian Current, the weather condition in Lofoten stays anomalously warm.
The colors of this weeks image come from the mix of two polarisations from the Copernicus Sentinel-1 mission which have been transformed into a single image. This remote noticing strategy allows us to discover where differences in between the polarisations are higher. These differences show up in tones of blue in the image, such as the choppy Norwegian Sea, wetlands and mires such as those on the northern idea of Andøya and damp snow on hills and in mountains (bottom-right corner of the image).
What appears in yellow shows what has less differences between polarisations, such as forests and other vegetated land, in addition to built-up locations.
Sentinel-1 is a radar mission and unlike optical cams, the images are typically black and white when they are gotten. By using a technology that lines up the radar beams sent out and gotten by the instrument in one orientation– either vertically or horizontally– the resulting information can be processed in a method that produces coloured images such as the one featured here.
This image, acquired on November 24, 2020, is likewise included on the Earth from Space video program embedded above.
The island chain of Lofoten in northern Norway captured by the Copernicus Sentinel-1 mission on November 24, 2020. (Image is cropped.
The Copernicus Sentinel-1 mission takes us over the island chain of Lofoten in northern Norway.
Extending around 175 km from north to south, the island chain makes up five primary islands (Austvågøya, Gimsøya, Vestvågøya, Flakstadøya, and Moskenesøya), as well as lots of small islands and skerries (rocky islets and reefs). Lofoten is understood for its unique surroundings, with significant mountains and peaks, sweeping beaches, deep blue fjords and sheltered bays.
Svolvær, the primary town and port of the Lofoten island group, lies on the southern coast of Austvågøya, the easternmost island of the island chain. The economy mainly depends on cod fisheries, with the towns population swelling during the generating season as anglers flock in. The fjord of Vestfjorden lies in between the island chain and the mainland.
