JapanFlux2024 JP-Fmt Field Museum Tama Hills

CO2 and H2O flux observation is conducted from 2013 at Field Museum Tamakyuryo (FM Tama) of the Tokyo University of Agriculture and Technology, which is located in a western suburb of Tokyo. FM Tama has a forest on hilly terrain that is near a residential area. For flux measurements, a 30-m-high walk-up tower was established on the floor (168 m asl) of a forest with a canopy height of about 20 m. The top of the tower was the highest position in the immediate area. Immediately south of the tower, the surface of the forest canopy was relatively uniform, with a slope of approximately 8 degree; however, the surface was complex in other directions. Deciduous trees (Quercus) were dominant around the tower, and Japanese cedar (Cryptomeria) was lightly distributed.
