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

The VIIRS/JPSS1 Moderate Resolution Terrain Corrected Geolocation 6-Min L1 Swath 750m Near Real Time (NRT) product, short-name VJ103MOD_NRT 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.

本数据集为VIIRS/JPSS1中分辨率地形校正地理定位6分钟L1横幅750米近实时(NRT)产品，简称VJ103MOD_NRT，其中包含了针对每个VIIRS中分辨率波段(M波段)视场(LOS)的地理定位字段，这些字段是在750米的名义分辨率下针对所有轨道进行计算的。位置及辅助信息对应于地球表面理想M波段上16个探测器视场中心的交点。采用数字地形模型来模拟地球表面。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、太阳天顶角和方位角、卫星天顶角和方位角，以及每个750米样本的土地/水域掩膜。头文件中还包含附加信息，以计算VIIRS各波段探测器中心的近似位置。该产品作为后续VIIRS中分辨率产品的输入，尤其是由陆地团队生产的产品。
