International Ozone Commission (IO₃C) of the International Association for Meteorology and Atmospheric Sciences (IAMAS) announces that the next International Quadrennial Ozone Symposium -- Sapporo 2000 -- will be held at the Hokkaido University, Sapporo, Hokkaido, Japan, from Monday 3 July through Saturday 8 July 2000. This Symposium will cover all aspects of the atmospheric ozone sciences.

First announcement (May 1999)

Location:

The Symposium will be held at Hokkaido University in the city of Sapporo. You are familiar to the name of Sapporo as the ozone station of Japan Meteorological Agency and as the place of 1972 winter Olympic Games. Sapporo is located at (lat. 43.1°N, long. 141.3°E; alt. 17 m) and is the capital of Hokkaido, the northernmost island of Japan. The average temperature of Sapporo in early July is 23.4°C in diurnal maximum and 14.5°C in diurnal minimum. It is accessed by domestic flights from Haneda Airport in Tokyo (taking 90 min., more than 30 flights available per day), from New Tokyo International Airport at Narita (taking 95 min., a few flights available per day), or from Kansai International Airport (taking 130 min., 10 flights available per day). Sapporo is a modern city with its history of only about 100 years since the settlement by the modern Japanese government.

Scientific topics:

The Symposium will solicit scientific papers on all aspects of atmospheric ozone such as:

• observations and analyses of total and vertical ozone distributions
• observation techniques and inter-comparisons
• tropospheric ozone, in particular past and future budgets and trends
• observations and budgets of trace constituents related to atmospheric ozone
• ozone chemistry
• model calculations: dynamics and chemistry coupling
• ozone-climate interaction
• ozone and ultraviolet radiation

The scientific program committee which will be set up subsequently will review the submitted papers before the acceptance for presentation. The presentation of a paper should be oral or on a poster. The detailed information on paper submission will be publicized in the second announcement to be issued in summer 1999.
