The
concept of the International Polar Year is of an international programme of
coordinated, interdisciplinary scientific research and observations in the
Earth’s polar regions to explore new scientific frontiers, to deepen our
understanding of polar processes and their global linkages, to increase our
ability to detect changes, to attract and develop the next generation of polar
scientists, engineers and logistics experts, and to capture the interest of
schoolchildren, the public and decision-makers.
The official period of the IPY will be from March 2007 until March 2009
to allow observations during all seasons, and the possibility of two summer
field seasons, in each polar region. The
geographic focus will extend over latitudes from approximately 60 deg to the
pole, both north and south. The IPY will
include a broad range of activities organized around a select number of
scientific themes.
Near-earth space, the domain of space weather, is an integral part of
the Earth system, providing one of several links between the Sun and
Earth. Many of the complex processes
permeating space link directly back to the high latitudes, making studies of
the high latitude ionosphere fundamentally important and its ongoing
variability intrinsically interesting.
During the
International Geophysical Year (IGY), 1957 – 58, two major tasks were
undertaken by IPS:
·
maps
of the F-region of the Antarctic ionosphere were produced for the IGY period,
·
and a short-term warning centre was established
to provide forecasts of solar and geomagnetic activity for the forthcoming 24
hours. The Australian Space Forecast
Centre (ASFC) arose from this early venture.
In part, the International Polar Year (IPY)
will commemorate the resounding successes of the IGY, which took place fifty
years ago. Many of today’s scientists
can remember the IGY launching their careers, or maybe more important
stimulating their imaginations while they were still at school. IPS has joined with other international
groups under the umbrella of ICESTAR (Interhemispheric Conjugacy Effects in Solar-Terrestrial and Aeronomy Research) to collect, archive and distribute
observations and reports on the Antarctic ionosphere.
