The circumference of the Arctic Circle at the 2019 Northern Hemisphere summer solstice UT 15:54 on 21 June is predicted to be 66° 33’ 51.083” N, calculated in the WGS84 ellipsoid is predicted to to be 15,983.793942075604 km or 9,931.869098263394 international miles or 8,630.558284058102 international nautical miles. Calculated in the WGS84 ellipsoid the area of the Arctic as defined by the Arctic Circle at the 2018 Northern Hemisphere summer solstice is predicted to be 21,204,911.158404 square km or 8,187,261.9699607 square international miles.
Circumference calculated, using Charles Karney's Online rhumb line calculations using the RhumbSolve utility: "RhumbSolve is accurate to about 15 nanometers (for the WGS84 ellipsoid)" or 0.000015 of a millimetre/millimeter or 0.00000059 of an inch. In emails to me from Charles Karney: "The accuracy of 15 nanometers that I quote is for paths up to half-way round the earth." "The accuracy for the Airy" [1830] "ellipsoid will be (very nearly) the same as for the WGS84 ellipsoid because the parameters are roughly the same." On RhumbSolve online: "RhumbSolve performs rhumb line calculations". "The path with a constant heading between two points on the ellipsoid at (lat1, lon1) and (lat2, lon2) is called the rhumb line (or loxodrome)". "NOTE: the rhumb line is not the shortest path between two points; that is the geodesic and it is calculated by GeodSolve. Area personally calculated in the WGS84 ellipsoid using Charles Karney's geodesic polygon calculations using the Planimeter utility. "The result for the area is accurate to about 0.1 m² per vertex."
