During the summer of 2001, the Swedish ice-breaker Oden sailed for the high Arctic on a research mission. During three weeks, an atmospheric program was carried out on a 1.5 x 3 km ice floe, starting out at 89°N, 0°E and drifting with the winds and the current.
The atmospheric measurements include a remote sensing program, with a 915MHz wind profiler, a Sodar and a scanning infra-red radiometer, a surface layer program, with profile and turbulence instrumentation on a 18-m mast, a micro-barograph array and two remote PAM-station, 5 and 8 km away on separate floes. A tethered sounding program with kite/balloon borne met-sensors, an aerosol package and a turbulence-flux package, was also in place and regular radiosoundings were also made every six hours. A large number of atmospheric chemistry and aerosol measurements were also part of the program.
This presentation will present this experiment and provide glimpses of boundary layer data taken in the very northern Arctic.
