VINDUR DATA FIELDS turns the wind blowing across Iceland into sound, live. Every ten minutes the automatic weather stations of the Icelandic Met Office report the wind's mean speed, its strongest gust and its direction: the map draws them, and the sound plays them as a slow ambient field that changes with the weather.
The sound has two layers. The bed is always on: five bands of air and aeolian harp from west to east, opening and rising as the wind strengthens and breathing with the gusts. The moments are notes: each time new readings arrive, a sweep crosses the island from west to east and every station with enough wind plays one note, higher for stronger wind, louder and longer for bigger gusts. The key follows the main wind direction around the circle of fifths.
Arrows show where the wind blows at each station. The colours and drifting streaks spread its strength between the stations; over the sea they come from a forecast model and are only drawn, not heard. Zoom with two fingers or the + and − buttons: what you see is what you hear.
Live follows the wind as it is now. Replay plays the last hours or days in a few minutes, one sweep per hour. Manual lets you move through the hours yourself. If the sound doesn't start by itself, press Start sound.
