Ice analyses and forecasts for the Arctic, Antarctic, and Great Lakes from the NAVY/NOAA Joint Ice CenterEntry ID: NAVY_NOAA_JIC
Abstract: The NAVY/NOAA Joint Ice Center (JIC) produces a global sea ice analysis each
week. The Arctic analysis is divided into West and East parts. The West
Arctic analysis chart extends from the Canadian Archipelago west to the Laptev
Sea; the East Arctic covers the remaining area. The Antarctic analysis is
presented on one chart. Ice analyses are primarily prepared from satellite
imagery (NOAA's ... Polar Orbiting Satellites, AVHRR in the visual and infrared
bands, and the Defense Meterological Satellite Program's SSM/I, passive
microwave sensor), ice reconnaissance flight data (radar and visual) and some
ship and shore station reports. The JIC regularly exchanges data with other
ice centers around the world.
Seven-day sea ice forecasts are produced weekly for the Arctic. Thirty-day
forecast charts for the Arctic are produced and updated every two weeks.
Antarctic forecasts are limited to the shipping season to periods of seven
days or less.
The JIC produces larger scale analyses of the Alaskan and Great Lakes regions
in support of the National Weather Service (NWS) offices in Anchorage and
Seasonal Outlooks are prepared about 90 days in advance of the shipping season
for the Alaskan North Slope, Baffin Bay/David Strait and Western Ross
Sea/McMurdo Sound regions. The two northern hemisphere outlooks are issued in
May and the southern hemisphere outlook is issued in October.
A bound volume containing all the weekly Arctic analyses is produced every year
(usually available in for the preceeding calendar year) and every other year
for the Antarctic (also usually available in June).
Also, though JIC is not a data archiving unit (the National Snow and Ice Center
Data Center (NSIDC) and National Climatic Data Center (NCDC) archive some JIC
products), JIC has a large holding of TIROS N data for the preceeding decade.
The JIC currently telefaxes weekly sea ice analyses and 30-day forecast
products to several hundred subscribers. 7-day and shorter range forecasts are
normally sent directly to users in the field via AUTODIN message or INMARSAT.
Outlooks are mailed except for a summary posted to the POLAR and ARCTIC.LOGISTS
bulletin boards maintained by OMNET, initiated in 1990.
All JIC products are available free of charge, except users are expected to bear
the cost of extraordinary means of communication, such as INMARSAT calls.
