The number of stations was as follows: 45 synoptic, 39 climatological and 37 precipitation
stations. At 6 of the stations agrometeorological observations were made, one summer stat-
ion was operated, 2 stations only for observations of wind, 2 for measurements of duration
of bright sunshine and 1 for agrometeorological observations.
Weather messages were sent from 58 Icelandic ships. Upper air observations were made
at Keflavík airport at 12 and 24 GMT. The total number of radiosonde observations
(RAOB) and wind observations (RAWIN) were 728. At the station írafoss samples were
collected for chemical analysis of some major pollutants in air and precipitation. Ozone
observations were made regularly at Reykjavík. Thirteen seismological stations were oper-
ated and 7 borehole strainmeter stations.
Weather reports and forecasts for Iceland and the surrounding sea banks were broadcast
9 times daily, and special voice broadcasts on short wave from coastal stations intended for
shipping 4 times daily. Forecasts for the deep sea banks were broadcast in Morse code in
Icelandic and English 4 times in 24 hours and forecasts for the banks were broadcast in
English 4 times daily. Forecasts with a 48 and 72 hours validity period were issued daily.
