At the same time, cooperating with research\ninstitutions having a climate numerical model, it contributes to reduction of errors in\ntemperature rise prediction derived from the climate numerical model and improvement of accuracy\nof prediction of various environmental changes. SGLI mounted on GCOM-C is the succession sensor\nof the Global Imager (GLI) mounted on ADEOS-II (MIDORI II) and is the Imaging Radiometer which\nmeasures the radiation from near-ultraviolet to thermal infrared region (380 nm-12 um) in 19\nchannels. Global observation of once for approximately every two days is possible at\nmid-latitude near Japan by observation width at ground greater than 1,000 km. In addition, SGLI\nrealizes high resolution than the similar global sensor and has a polarized observation function\nand a multi-angle observation function.\n\nBands\n\n\n**Pixel Size**\n\n4638.3 meters\n\n**Bands**\n\n| Name | Units | Min | Max | Pixel Size | Description |\n|---------------|-------|-----|---------|------------|------------------------------|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|\n| `LST_AVE` | K | 0\\* | 65531\\* | meters | Temperature of land surface. |\n| `LST_QA_flag` | | | | meters | LST QA |\n| Bitmask for LST_QA_flag - Bits 0-1: Terrain type - 0: water (land fraction = 0%) - 1: mostly water (0% \\\u003c land fraction \\\u003c 50%) - 2: mostly coastal (50% \\\u003c land fraction \\\u003c 100%) - 3: land (land fraction = 100%) ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||\n\n\\* estimated min or max value\n\nImage Properties\n\n**Image Properties**\n\n| Name | Type | Description |\n|---------------------|--------|-----------------------------------------------------------------|\n| ALGORITHM_VERSION | STRING | Algorithm version |\n| GRID_INTERVAL | STRING | Spatial resolution |\n| GRID_INTERVAL_UNIT | STRING | Unit of GRID_INTERVAL |\n| IMAGE_END_TIME | STRING | Image acquisition end time |\n| IMAGE_START_TIME | STRING | Image acquisition start time |\n| PROCESSING_RESULT | STRING | Good, Fair, Poor, NG |\n| PROCESSING_UT | STRING | Processing time |\n| PRODUCT_FILENAME | STRING | Source filename |\n| PRODUCT_VERSION | STRING | Product version |\n| SATELLITE_DIRECTION | STRING | Satellite orbit direction - A: Nighttime data - D: Daytime data |\n| LST_AVE_OFFSET | STRING | Offset |\n| LST_AVE_SLOPE | STRING | Slope |\n\nTerms of Use\n\n**Terms of Use**\n\nThis dataset is free to use without any restrictions (including commercial use).
