Present and Future of Earth Environmental Monitoring System in Japan Korehiro Maeda and Osamu Ryuguji Earth Observation Center(EOC), National Space Development agency of Japan (NASDA) 1401 Ohashi, Hatoyama-machi,Hiki-gun,Saitama-ken 350-03 Japan ABSTRACT Earth environment is one of the most important items for human-beings.Japan is also interested in earth environment problem. In order to resolve such problem, it is necessary to observe the whole earth from space. NASDA developed both space segment and ground segments for MOS-1 (Marine Observation Satellite-1) and MOS-lb. NASDA is also developing space and ground segments for JERS-1 (Japanese Earth Resources Satellite-1) in collaboration with MITI (Ministry of International Trade and Industry) and developing ground segment for ERS-1(European Remote Sensing satellite-1). NASDA is developing ADEOS (ADvanced Earth Observing Satellite) which has two core sensors and 6 AO sensors. Concerning domestic AO sensors, two equipments were proposed by the Environment Agency and one equipment was proposed by MITI.Concerning foreign AO sensors, two equipments were proposed by NASA and one equipment was proposed by CNES. TRMM (Tropical Rainfall Measuring Mission) is a joint project between NASA and NASDA and NASDA will develop precipitation radar in collaboration with CRL (Communications Research Laboratory). NASDA will participate in international polar platform program and develop JPOP (Japanese Polar Platform). In this paper,the outline of earth environmental monitoring by MOS-1 data is presented and the present and future earth environmental monitoring system is also presented. KEY WORDS:MOS-1,M0S-lb,JERS-1,ERS-1,ADEOS,TRMM,JPOP,Earth Environment 1 INTRODUCTION Global change problem is increasingly important for human-beings.Earth environment can be monitored from space. Earth observation satellite is one of most important means to monitor global change of the earth environment. NASDA launched the first earth observation satellite named Marine Observation Satellite-1 (MOS-1) on Feb.19,1987 and launched MOS-lb on Feb.7,1990. MOS-1 and MOS-lb data are received by 11 MOS-1 receiving stations in the world. Since there is no tape recorder mounted on MOS-1 .monitored area is limited to the area covered by these stations. On the other hand,future Japanese observation satellites will have on-board data recorders and some satellites will use data relay satellite. By these satélites, not only global data but also regional/local data can be obtained under the limitations of capacity of data recorders and data transmission line. In order to contribute to the earth environment problem, only development and operation of space and ground segments are not sufficient. For that local, regional and global data set should be continuously constructed and provided to those who is involved in earth environment. In this paper, present status of earth environment monitoring system by MOS-1 and future system are described and evaluated. 2.PROBLEM OF EARTH ENVIRONMENTAL MONITORING We have many environmental problems in the world. Examples of such problems are deforestation, expansion of desert, polution of ocean, increase of sea surface temperature, change of marine current, abnormal weather, acid rain, increase of carbon dioxide, decrease of ozone and others. In order to resolve such problems, it is necessary to .first of all, understand the whole earth as a earth system and to take countermeasures. The former is problem of earth science and the latter is problem of technology, economy and politics. Concerning earth science, local, regional and global data concerning earth system should be gathered continously. Concerning the countermeasures, new technology should be developed and some space technology can be applied. In Japan, there are several environmental problems and more people are interested in these problems. Japanese old prime minister Mr.Uno stressed in Arche summit held in Paris in July,1989 that environmental monitoring from space should be promoted. Many Japanese agencies and universities are studying and developing for global environmental problems. Most important means for global environmental monitoring is earth observation satellite system consisting of space and ground segments. Global change can be monitored continously for the first time by using earth observation satellite. In order to establish earth environmental monitoring system, the following requirements should be met. (1) Space segment - To observe the whole earth continously - To observe various targets in the required precission in the required repetition by using combination of sensors - To record and process sensor data onboard (2) Ground segment - To receive, record, process and distribute - To develop useful data sets and distribute - To have access to directry of any data from anywhere To provide requested data through communication data network - To transfer sea, ground truth and other data via satellite
