概要

From 5 to 14 March, 2002, the Arctic Airborne Measurement Program 2002(AAMP02) was conducted on a round-trip flight between Nagoya, Japan, and Longyearbyen, Svalbard, via Anchorage and Barrow, U.S.A. and the North Pole using a chartered twin-jet aircraft, the Gulfstream-II(G-II). On board the G-II, in-situ measurements of the ozone concentration were carried out every 12s in order to obtain information on air mass differences and advection. Vertical profiles of the ozone concentration observed over Longyearbyen agreed well with those observed by ozone sonde launched around the same time from Ny-Ålesund, about 100km north of Longyearbyen. The ozone variations observed in the upper troposphere and lower stratosphere showed negative correlation with the CO_2 concentration, suggesting vertical displacements of air masses. However, it was also observed that the ozone concentration fluctuated considerably with little consistency with the meteorological field.
