The geographical distribution of the intensity of solar radiation on the horizontal surface of Tokyo was measured during a day period, between March 8th and March 24th, 1958. Both stationary and mobile technique of measurement were used. Stationary observation was by means of four Eppley-type and one Gorczinski-type pyrheliometers, installed at five locations in Tokyo, pre-selected according to the type of urban land use (central admini-strative, central and western residential, eastern industrial and blaneda International Air Port in the south), with the results of successive observations of the solar radiation intensity (measured every 15 seconds) being recorded on electric self-recording gauges. The ultimate goal was to ascertain typical patterns of diurnal change in the intensity of radiation in different parts of the city. In addition, a mobile technique of measurement was developed to observe the intensity of radiation at from 30 to 40 other locations. Observations were made on March 8th, 13th, 17th, 19th, and 24th, with two or three groups participating in each case. Each group carried a Gorczinski-type pyrheliometer and observed the radiation intensity at different places, moving by car and/or suburban electric train from one place to the next, following a scheduled route. A day of observation began at 0930 and ended at 1600, with each group being able to make measurements in from 15 to 17 places. The results obtained were all converted into relative intensities, expressed as percentages of like observations, recorded at corresponding times on the roof of a building of Tokyo University of Education, located near the center of the city. These are shown in Figs. 1 to 10. Marked regional differences in the intensity of solar radiation were recognized, even within the Tokyo urban area. Differences of as much as 50 percent in relative intensity were noted. Maximum intensities were recorded in the northwest sectors of the city and suburbs, where the figures were over 110 percent of the established standard. Lowest intensities were seen in the western lowlands and along the bay-the figures being only 40 to 50 percent of "normal". The entire report is to be published later.
