VIIRS/JPSS1 Imagery Resolution Terrain Corrected Geolocation 6 Min L1 Swath 375m NRT

The VIIRS/JPSS1 Imagery Resolution Terrain Corrected Geolocation 6-Min L1 Swath 375m Near Real Time (NRT) product, short-name VJ103IMG_NRT includes the geolocation fields that are calculated for each VIIRS imagery resolution band (I-band) Line of sight (LOS) for all orbits at the nominal resolution of 375 m. The locations and ancillary information correspond to the intersection of the centers of each Field of View (FOV) from 32 detectors in an ideal I-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 VNP03IMG_NRT 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 375m 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 a large number of subsequent VIIRS Imagery Resolution products, particularly those produced by the Land team.

该VIIRS/JPSS1影像分辨率地形校正地理定位6分钟L1条带375米近实时(NRT)产品，简称VJ103IMG_NRT，包含了针对每个VIIRS影像分辨率波段（I波段）视场（LOS）在标准分辨率375米下所有轨道计算得到的地理定位字段。这些位置及辅助信息与地球表面理想I波段中32个探测器视场中心的交点相对应。通过数字地形模型对地球表面进行建模。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。VNP03IMG_NRT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、太阳天顶角和方位角、卫星天顶角和方位角以及每个375米样本的土地/水域掩膜。此外，头部信息中还包含附加信息，以便计算任何VIIRS波段的探测器中心的大致位置。该产品作为大量后续VIIRS影像分辨率产品的输入，尤其是那些由陆地团队生产的影像产品。
