We first analyzed aerial, satellite and surface photographs of Hiroshima taken in 1939, 1945, 1947, 1972, 1980 and 1982, in time sequence. It is rather difficult to recognize traces of damage caused by the atomic bombing from surface level with the few exceptions such as the Atomic Bomb Memorial Dome. However, the ground surface pattern of central Hiroshima analyzed by LANDSAT MSS data shows similarities to damage caused by the atomic bombing and the distribution of residual radioactivities. 相似文献

Observations of satellite images have shown that the snow melting in mountainous area proceeds more repidly in the east-facing slope of the valley than in the west-facing one. The energy for melting snow consists of the total from the atmosphere and from the solar rays. The diurnal variation of the solar energy into the snow in the east-facing slope differs from that in the west-facing slope. This causes the heighest value of the instantaneous energy for melting snow to occur in the west-facing surface. As one of the reasons for the above tendency, the difference of the heighest value to melt snow may be taken into account. 相似文献
