For the purposes of this report, the geographical coordinates of Greenland are 35.994 deg latitude, -94.175 deg longitude, and 1,391 ft elevation.
The topography within 2 miles of Greenland contains only modest variations in elevation, with a maximum elevation change of 482 feet and an average elevation above sea level of 1,363 feet. Within 10 miles contains only modest variations in elevation (1,168 feet). Within 50 miles contains very significant variations in elevation (2,238 feet).
The area within 2 miles of Greenland is covered by cropland (57%) and trees (37%), within 10 miles by trees (46%) and cropland (44%), and within 50 miles by trees (59%) and cropland (36%).
This report illustrates the typical weather in Greenland year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.
Temperature and Dew Point
There are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Greenland.
For each station, the records are corrected for the elevation difference between that station and Greenland according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at Greenland is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Greenland and a given station.
The stations contributing to this reconstruction are: Drake Field (97%, 1.8 kilometers, north); Fort Smith Municipal Airport (1.3%, 76 kilometers, south); Sallisaw Municipal Airport (1.2%, 84 kilometers, southwest); and Russellville Municipal Airport (0.7%, 128 kilometers, southeast).
All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid.
