  • MESSR Data from JAXA/EOC Japan

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560221-JAXA.xml
    Description:

    A multi-spectral electronic self-scanning radiometer (MESSR) is an electronic-scan-type radiometer which detects reflected solar rays from the earth's surface in two visible bands and two near-infrared bands. It is equipped with two camera systems that are parallel with the direction of flight of the satellite. Each camera system is comprised of two optical units; one for the visible range and the other for the near-infrared range. Each camera system scans a width of 100 km of the earth surface at right angles to the direction of flight of the satellite. When the two systems are used at the same time, a width of 185 km can be scanned. Each has 2048 charge-coupled devices (CCDs) for detection purposes, thus achieving a resolution of 50 m for the earth's surface. --------------------------------------------------------------------------- MESSR --------------------------------------------------------------------------- Wavelength/ micron Frequency 0.51 - 0.59 0.61 - 0.69 0.72 - 0.80 0.80 - 1.10 Resolution 50m Sensitivity/ 39dB SN Swath 100Km Application Fields Band 1 Land: Plant distribution, Snow cover distribution (0.51-0.59) Distribution of volcanic ash, Land usage Ocean: Water quality of coastal sea areas and lakes, Red tide, Geological shape at the bottom of the sea in coastal areas ( with high transmission factor) Band 2 Land: Land usage, Geological structure, Plant (0.61-0.69) distribution, Snow cover distribution, Distribution of volcanic ash Ocean: Water quality of coastal sea areas and lakes, Red tide, Water vortex Band 3 Land: Ground surface water, Moor, Water resources (0.72-0.80) Geological structure, Plant distribution Band 4 Land: Mapping of ground surface water and outer layer (0.80-1.1) composition, Flood areas, Lakes and Ponds, Plant distribution Ocean: Ice distribution, Water boundaries Channel

  • MSR Data from JAXA Japan

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560172-JAXA.xml
    Description:

    As a parabolic antenna revolves, the microwave scanning radiometer (MSR) continuously scans the earth surface conically for a width of 317 km. During this process, the MSR receives weak radio waves in the two frequency bands of 23.8 and 31.4 GHz. Its resolution in terms of earth area is 32 km in the 23.8 GHz band and 23 km in the 31.4 GHz band. --------------------------------------------------------------------------- MSR --------------------------------------------------------------------------- Wavelength/ GHz Frequency 23.8 31.4 Resolution 32Km 23Km Sensitivity/ 1K 1K SN Swath 320Km Application Fields 23.8GHz Water vapor content, rainfall area measurement and snowfall measurement 31.4GHz Ice measurement, measurement of water content in cloud and snowfall measurement

  • Sea Surface Temperature (SST) Around Japan from MOS-1/1b VTIR

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560116-JAXA.xml
    Description:

    This study have been done as a part of the activities in Japan for 1992 International Space Year(ISY). The object is to develop the algorithm to create SST dataset using satellite data. MOS-1/VTIR has the superior function in order to observe the sea near Japan area simultaneously. The Sea Surface Temperature dataset is processed with multiple VTIR data which is observed during 10 days period and reduced cloud effect for SST estimation. The dataset contains Sea Surface Temperature of seasonal change at the sea near Japan and change pattern of Kuroshio current in a long time since Jun. 1987. SST were analyzed by the processing of atmospheric correction using Split Window's formula. Coverage area is about 300 km South/North and East/West each way including Japan. Resolution is 2.7 km. Total 21 SST datasets have been created since Jun.1989 and it has been creating in a cycle of once a month or two months. This datasets can be distributed with free charge by CD-ROM.

  • VTIR Data from JAXA/EOC Japan

    https://cmr.earthdata.nasa.gov/search/concepts/C1214560210-JAXA.xml
    Description:

    A visible and thermal infrared radiometer (VTIR) covers one visible band and three thermal infrared bands to detect thermal radiation from the earth's surface. This radiometer is equipped with a rotating scanning mirror which mechanically scans the earth's surface from right to left, at right angles to the direction of flight of the satellite. When the mirror deviates from the direction of the earth surface, it looks at an internal black body unit and at deep space, and thus obtains thermal infrared calibration data. The VTIR's resolution in terms of the earth surface is some 900 m in the visible-ray band and about 2,700 m in the thermal infrared bands. The scanning width of the VTIR is so wide (1,500km) that a particular area on the earth surface can be observed continuously for ten-odd days by using its side-lap. -------------------------------------------------------------------------- VTIR -------------------------------------------------------------------------- Wavelength/ micron Frequency 0.5-0.7 6.0-7.0 10.5-11.5 11.5-12.5 Resolution 900m 2.7km Sensitivity/ 55dB 0.5k SN Swath 1500Km Application Fields Band 1 Snow cover distribution (0.5-0.7) Ice distribution Cloud distribution Band 2 Water vapor distribution in upper layer (6-7) (Temperature zone) Detection of thin cirrus cloud Band 3 Snow cover distribution (10.5-11.5) Ice distribution Monitoring of sea water flow Sea surface temperature Band 4 Snow cover distribution (11.5-12.5) Ice distribution Monitoring of sea water flow Cloud distribution Sea surface temperature
