3. PRESENT STATUS OF EARTH ENVIRONMENTAL MONITORING NASDA developed and launched MOS-1 by N-II rocket from Tanegashima Space Center, NASDA on Feb.19,1987. As a development, NASDA conducted field verification experiment during 1981 FY-1983 FY and MOS-1 airborne verification experiment during 1984 FY-1985 FY in collboration with participating organizations before the launch of MOS-1. After the launch of MOS-1, NASDA conducted MOS-1 Verification Program (MVP) during 1987 FY- 1989 FY in collaboration with 60 domestic organizations and 15 foreign organizations. Through these verification, performance of MOS-1 observation system and the utility of MOS-1 data in various fields of applications have been evaluated. During 1989 FY, NASDA continued evaluation of MOS-1 data in collaboration with 20 domestic organizations and 3 foreign organizations. As a result of evaluation, MOS-1 data can be utilized in various fields of applications including environment monitoring. MOS-lb was successfully launched by H-I rocket on Feb.7,1990 By using MOS-1 and MOS-lb, repetition of observation has been doubled and this will contribute to earth environment monitoring. Unfortunately, MOS-1 has no on-board tape recorder. However, there are 11 MOS-1 Table 1 Examples of Environmental Monitoring Results of MOS-1 Classification Earth Environmental Monitoring Items Sensor Data Band Number Example of Test Sites Ocean •River effluents, Coastal water MESSR Band 1,2 Sea around Japan, Yellow Sea • Water quality MESSR Band 1,2 Tokyo Bay, Malacca Straits (Chrolophyl, turbidity etc.) •Colored water from submarine volcano MESSR Band 1,2,3 Near South loh Jima • Sea surface temperature VTIR Band 3,4 Sea around Japan •Current interface VTIR Band 3,4 Off shore of Sanriku • Water region VTIR Band 3,4 Off shore of Sanriku, Kurosio current •Sea temperature, Sal inity, Wave height, DCS - Southern sea of Japan, Bering Sea Wave spctrum,Under water ambient noise • Sea ice distribution MSR/VTIR/MESSR Off shore of Monbetsu, Sea of Okhotsk, Ocean of Antarctica (Near Showa Base) Land • Land uti1ization MESSR Band 1,2,3,4 Tokyo,Hiratsuka, Singapore • Cultivation MESSR Band 1,2,3,4 Suphan Buri (Thailand) • Forest MESSR Band 1,2,3,4 Hokkaido, Cihu, Gunma, Thailand • Mineral deposits MESSR Band 1,2,3,4 Pusan (Korea) • Flood MESSR Band 1,2,3,4 Agano River • Volcano MESSR Band 1,2,3,4 Oshima, Miyakejima, Sakurajima • Land siide MESSR Band 1,2,3,4 Nagano, Mt.Ontake •Lake, Reservoir MESSR Band 1,2,3,4 Kasumigaura, Lake Biwa, Singapore • Snow distribution MSR/VTIR/MESSR Band 1,3 or 2,4 Hokkaido Atmosphere •Water vapor, Cloud liquid MSR Band 1,3 or 2,4 Hachizyojima, Chichijima, Minamidaitojima • Precipitation area MSR Band 1,3 or 2,4 Radar zone from Mt.Fuji •Jet atmospheric current,cirrus VTIR Band 2 (6-7 // m) Japan and its surroundings •Cloud, Typhoon, Flont etc. VT IR/MESSR/MSR Japan and its surroundings receiving stations in the world. So,most area is covered by these ground stations. MOS-1 has 4 mission instruments:MESSR (Multi- spectral Electronic Self-Scanning Radiometer), VTIR (Visible and Thermal Infra-red Radiometer), MSR (Microwave Scanning Radiometer) and DOST ( Data Collection System Transponder). Earth environmental monitoring results are shown in Table 1. Concerning ocean, sea surface temperature can be obtained by using VTIR Band 3 and 4. Turbidity can be monitored by MESSR. Deforestation can be also monitored by MESSR. Water vapor and cloud liquid can be obtained by using MSR 23 GHz and 31GHz. Moreover, sea ice distribution can be obtained under all weather condition by using MSR. Example of deforestation obtained by MOS-1 is shown in Fig.l. By using Landsat MSS data (Dec.31,1984) and MOS-1 MESSR (Jan.20,1989), deforestation in Kanohanaburi, Thailand were detected, where NVI (Normalized Vegetation Index) was obtained for the MSS data and maximum likelihood method was applied to MESSR data.Changes from grass,bush to bare soil,from forest to bare soil and from forest to grass,bush are shown in Fig.l.
