Tromsø, [b] officially the Tromsø Municipality, [c] is a municipality in Troms county, Norway. The administrative centre of the municipality is the city of Tromsø.Other notable settlements in the municipality include the villages of Bjerkaker, Ersfjordbotn, Jøvika, Kaldfjord, Kjosen, Kroken, Kvaløysletta, Lakselvbukt, Melvika, Movik, Oldervik, Sandneshamn, Sjursnes, Sommarøy, and Tromsdalen.
The nights shorten quickly. By 21 February the sun is above the horizon from 7:45 am to 4:10 pm, and by 1 April it is above the horizon from 5:50 am to 7:50 pm (daylight saving time). If we include astronomical twilight as "not night", then Tromso only has 14 hours of night on the winter solstice.
The sheltered valleys in the interior of Troms have the highest tree line (summer warmth and length is the limiting factor), with downy birch reaching an elevation of 700 m (2,300 ft) on the southern slope of Njunis; all over Troms county birch trees forms the tree lines, often 200 metres (660 ft) above other trees.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
Length of one degree (black), minute (blue) and second (red) of latitude and longitude in metric (upper half) and imperial units (lower half) at a given latitude (vertical axis) in WGS84. For example, the green arrows show that Donetsk (green circle) at 48°N has a Δ long of 74.63 km/° (1.244 km/min, 20.73 m/sec etc) and a Δ lat of 111.2 km ...
Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Arctic Circle is the southernmost latitude in the Northern Hemisphere at which the centre of the Sun can remain continuously above or below the horizon for twenty-four hours; as a result, at least once each year at any location within the Arctic Circle the centre of the Sun is visible at local midnight, and at least ...
The definition of geodetic latitude (ϕ) and geocentric latitude (θ) The geocentric latitude is the angle between the equatorial plane and the radius from the centre to a point of interest. When the point is on the surface of the ellipsoid, the relation between the geocentric latitude (θ) and the geodetic latitude (ϕ) is:
The geocentric altitude is a type of altitude defined as the difference between the two aforementioned quantities: h ′ = R − R 0; [3] it is not to be confused for the geodetic altitude. Conversions between ECEF and geodetic coordinates (latitude and longitude) are discussed at geographic coordinate conversion .
