International Antarctic Analysis Centre (continued)

1. a daily analysis of constant pressure charts for 1000, 700, 500 and 300 mb levels over Antarctica and the area extending north to 30°S


2. the daily issue of facsimile and coded statements of the 700, 500 and 300 mb analyses for 00 GMT issued nine hours after map time;


3. subsequent reanalysis of these charts following the entry of delayed data; and


4. microfilms made of these charts seven days after the close of each month airmailed to each member country of SCAR and three other interested organisations.

The IAAC was an ambitious project which made a useful contribution to the knowledge of the meteorology of the Antarctic and the Southern Ocean and is a tribute to the dedication of Henry Phillpot and the Australian and international meteorologists who worked so diligently. Argentina, France, Japan and the US and USSR continued to provide meteorologists to support Henry Phillpot in carrying out this important work. In 1965 Australia accepted the invitation of WMO to operate one of the three World Meteorological Centres of the World Weather Watch, the Australian centre being located in Melbourne and the other two in Moscow and Washington. This relieved the IAAC of the responsibility of preparing and issuing synoptic analyses for the Antarctic and the Southern Ocean but the work that Henry Phillpot and his colleagues had pioneered was a useful precedent for later efforts. It was ironic that at that stage meteorological and telecommunication satellites were beginning to remedy the observational and telecommunications difficulties which had made the work of the IAAC so difficult.
