VIIRS/JPSS1 Moderate Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m NRT

The Near Real Time (NRT) VIIRS/JPSS1 Moderate Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m (VJ103MOD_NRT) product includes the geolocation fields that are calculated for each VIIRS moderate resolution band (M-band) Line of sight (LOS) for all orbits at the nominal resolution of 750 m. The locations and ancillary information correspond to the intersection of the centers of each Field of View (FOV) from 16 detectors in an ideal M-band on the Earth's surface. A digital terrain model is used to model the Earth's surface. The main inputs are the spacecraft attitude and orbit ephemeris data, the instrument telemetry and the digital elevation model. The geolocation fields contained within the VNP03MOD Geolocation files include geodetic latitude, longitude, surface height above the geoid, solar zenith and azimuth angles, satellite zenith and azimuth angles, and a land/water mask for each 750m sample. Additional information is included in the header to enable the calculation of the approximate location of the center of the detectors for any of the VIIRS bands. This product is used as input by subsequent VIIRS Moderate Resolution products, particularly those produced by the Land team.

该实时近地 (NRT) VIIRS/JPSS1 中分辨率地形校正地理定位 6 分钟 L1 扫描宽度 750 米 (VJ103MOD_NRT) 产品包含针对每个 VIIRS 中分辨率波段 (M波段) 视线 (LOS) 的地理定位字段，这些字段是在所有轨道的预定分辨率 750 米下计算的。位置及辅助信息对应于地球表面理想 M 波段 16 个探测器视场 (FOV) 中心的交点。地球表面模型是通过数字地形模型来构建的。主要输入包括航天器姿态和轨道摄动数据、仪器遥测数据和数字高程模型。VNP03MOD 地理定位文件中包含的地理定位字段包括大地纬度、经度、相对于大地水准面的地表高度、太阳天顶和方位角、卫星天顶和方位角以及每个 750 米样本的陆地/水域掩膜。此外，头部信息中还包含了用于计算任何 VIIRS 波段探测器中心近似位置的相关信息。该产品作为后续 VIIRS 中分辨率产品的输入，尤其是那些由陆地团队生产的产品。
