DIAS_GRENE_Satellite_ALOS_DSM30 dataset

Three scale-types of datasets observed by new generation of remote sensing satellites (including TERRA, AQUA, ADEOS-II) in addition to TRMM and DMSP series, which were providing enhancement of observing capabilities to quantify critical atmospheric, surface, hydrologic and oceanographic data during CEOP time periods are available. 250 km square snapshots of the highest resolution raw radiances (with geographic location, i.e. level 1) remote sensing data at the 35-51 in situ reference sites are archived. ■Satellite ALOS： The Advanced Land Observing Satellite "DAICHI" (ALOS) has been developed to contribute to the fields of mapping, precise regional land coverage observation, disaster monitoring, and resource surveying. ALOS has three sensors: the Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM), which is comprised of three sets of optical systems to measure precise land elevation; the Advanced Visible and Near Infrared Radiometer type 2 (AVNIR-2), which observes what covers land surfaces; and the Phased Array type L-band Synthetic Aperture Radar (PALSAR), which enables day-and-night and all-weather land observation. ■Sensor Panchromatic Remote-sensing Instrument for Stereo Mapping (PRISM) ■Product level L2【DSM】(PRISM) ■Resolution 30m ■Product Area East Asia～Around Southeast Asia (longitude90～150、latitude10～55)

本数据集包含由新一代遥感卫星（含TERRA、AQUA、ADEOS-II）以及TRMM、DMSP系列卫星获取的三类尺度数据集；上述卫星在CEOP观测时段内，强化了对关键大气、地表、水文与海洋学数据的量化观测能力。现已归档35至51个原位参考站点处的最高分辨率原始辐射遥感数据快照（含地理坐标，即一级数据），每幅快照覆盖范围为250平方千米。
■卫星ALOS：
先进陆地观测卫星"大地"（ALOS，别名DAICHI）旨在为测绘、精准区域地表覆盖观测、灾害监测与资源勘查领域提供支撑。该卫星搭载三台传感器：其一为用于立体测绘的全色遥感仪器（Panchromatic Remote-sensing Instrument for Stereo Mapping，缩写PRISM），该仪器由三套光学系统组成，可精准获取陆地高程数据；其二为第二代先进可见近红外辐射计（Advanced Visible and Near Infrared Radiometer type 2，缩写AVNIR-2），用于对地表演盖物进行观测；其三为相控阵型L波段合成孔径雷达（Phased Array type L-band Synthetic Aperture Radar，缩写PALSAR），可实现全天时、全天候陆地观测。
