Summary of the annual report
of the Icelandic Meteorolagical Office 1983.
Sixty personnel positions were occupied during 1983 in the following divisions
of the Icelandic Meteorological Office: administration, forecasting, telecommunications,
climatological, meteorological research, instrumental, geophysical, aviation observation
and sea ice research divisions. 2% provisional positions were occupied.
The number of stations was as follows: 43 synoptic, 40 climatological and 37 preci-
pitation stations. At 6 of the stations agrometeorological observations were made.
Two summer stations were operated, 2 stations only for observations of wind and 2 for
measurements of duration of bright sunshine.
Weather messages were sent from 61 Icelandic ships. Upper air observations were
made at Keflavík airport at 12 and 24 GMT. The total number of radiosonde observations
(RAOB) was 720 and wind observations RAWIN) were 714. At the station Irafoss
samples were collected for chemical analysis of some major pollutants in air and
precipitation. Ozone observations were made regularly at Reykjavík. Twelve seismo-
logical stations were operated 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 costal stations,
intended for shipping 4—5 times daily. Forecasts for the deep sea banks were
broadcast in Morse code in Icelandic and English 4 times in 24 hours. Forecasts with a
48 hours validity period were issued once a day, and in addition 72 hours forecasts start-
ing Sept. 29. Fascimilic synoptic weather maps were transmitted. Weather charts were
presented by a meteorologist in the Icelandic Television every operational day.
The monthly issues of Veðráttan were published for the months January—December
1982 and annual summary for 1981.
Preliminary Seismogram Readings were issued weekly and send to subscribers.
