4. Enhancement of the value of human life
The truly great contributions of Elachi, Fugono and Okamoto have helped make it possible to record precise Earth environment data with good accuracy and homogeneities on land, over oceans and polar regions, together with tropical rainfall which is considered to greatly affect global climate. Their work has enabled a practical earth environment observation system using radars. This system has improved the quantitative and logical understanding of the present state of the Earth's environment and the changing trends.
The data obtained from this radar system have good synergetic effects with other data from conventional systems, such as optical sensors or passive microwave sensors. Data gathered from these systems have been important and essential datasets that are available freely to be accessed on Internet web sites by peoples all over the world.
Many scientists and engineers are analyzing the complicated changes in the global environment, and they are steadily clarifying the causes of global environmental issues. These huge amounts of data are also contributing to the developments of simulation technologies such as the Earth Simulator that predict changes of climate, water circulation, ecological systems and other environmental systems. Major advances in scientific knowledge and progress in simulation have the potential to contribute concretely to our life by helping preserve the Earth's environment, manage water resources, and contribute to diverse applications in agriculture, forestry, fishery, and industry. This achievement has taken a great step toward improving the quality of life for humanity.
