Rainfall

To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Andøya Andenes Airport experiences some seasonal variation in monthly rainfall.

Rain falls throughout the year at Andøya Andenes Airport. The most rain falls during the 31 days centered around October 14, with an average total accumulation of 3.2 inches.

The least rain falls around May 13, with an average total accumulation of 1.4 inches.

Snowfall

We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Andøya Andenes Airport experiences some seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 6.3 months, from October 20 to April 30, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around January 31, with an average total liquid-equivalent accumulation of 0.9 inches.

The snowless period of the year lasts for 5.7 months, from April 30 to October 20. The least snow falls around July 16, with an average total liquid-equivalent accumulation of 0.0 inches.

Due to its extreme latitude, Andøya Andenes Airport experiences polar day (also known as the midnight Sun) during the summer and polar night during the winter. These are periods of time in which the sun is continuously above or below the horizon for more than one day. The precise start and end dates of polar day and night vary from year to year and depend on the precise location and elevation of the observer, and the local topography.

In the summer at Andøya Andenes Airport during 2017, the Sun is continuously above the horizon for 2.1 months, rising at 1:16 AM on May 19, and not setting again until 1:02 AM on July 24.

In the winter at Andøya Andenes Airport during 2017, the Sun is continuously below the horizon for 1.5 months, setting at 12:12 PM on November 28, and not rising again until 11:37 AM on January 13.

Daylight saving time (DST) is observed at Andøya Andenes Airport during 2017, starting in the spring on March 26, lasting 7.1 months, and ending in the fall on October 29.

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The perceived humidity level at Andøya Andenes Airport, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

Temperature and Dew Point

Andøya Andenes Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.

In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.

The stations on which we may fall back are Evenes; Bardufoss Airport; Tromsø Airport, Langnes; and Sørkjosen Airport.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

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.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
