October 1998 Tokyo, Japan Turbulent transfer and energy balance over high-density urban surface with minimal greenspace. Innovative experimental design uses 35 m industrial crane for positioning of instruments. Manabu Kanda (PI) and Jamie Voogt
Fall 1995 - Spring 1996 Fukuoka, Japan Wind tunnel study of controlled roughness effects on neutral flow. Use of Laser Doppler anemometry to study flow characteristics within and above model canopy. Hiromasa Ueda
Summer 1989 Vancouver, Canada Turbulent transfer and energy balance over medium-density suburban surface with considerable amount of greenspace. Most detailed and comprehensive study of turbulence transfer characteristics in the urban environment at the time. First closure of urban energy balance using direct measurements of all turbulent fluxes. Tim Oke
Summer 1986 Vancouver, Canada Pilot study of turbulent transfer over suburban surface. First measurements of urban heat flux cospectra. Tim Oke and Douw Steyn
Summer 1984 Swiss plateau ('Mittelland'), Switzerland Regional albedo measurements of various surface covers. Albedo measurements using a motor glider as instrument platform for radiation sensors. Atsumu Ohmura and Koni Steffen
