Abstract
This study investigated a ensemble mean characteristics of urban environment within a pedestrian level based on a mobile observation. The mobile observation was conducted using globe anemometer thermometer, developed by Nakayoshi et al. (2015), which measure three type of globe temperature and air temperature to obtain the net shortwave radiation and longwave radiation, and wind speed. The observation was taken place for 20 days, and three times per day. The route is set to be in a residential area of Tokyo, exnteded to 3.4 km along the way.
The ensemble average revealed that the wind speed is enhanced due to the topography effect if the obstraction of the surface obstactles are less effective, i.e. in a street parallel to the synoptic wind direction. Air temperature distribution within a urban canopy also depend on the topography as the temperature becomes high in a slope directed to the solar angle in addition to the sky view factor.
