MODIS/Aqua Geolocation Fields 5-Min L1A Swath 1km - NRT

The Near Real Time (NRT) geolocation fields are calculated for each 1 km MODIS Instantaneous Field of Views (IFOV) for all orbits daily. The locations and ancillary information corresponds to the intersection of the centers of each IFOV from 10 detectors in an ideal 1 km 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, the instrument telemetry and the digital elevation model. The geolocation fields include geodetic Latitude, Longitude, surface height above geoid, solar zenith and azimuth angles, satellite zenith and azimuth angles, and a land/sea mask for each 1 km sample. Additional information is included in the header to enable the calculation of the approximate location of the center of the detectors of any of the 36 MODIS bands. This product is used as input by a large number of subsequent MODIS products, particularly the products produced by the Land team.The shortname for this product is MYD03.

针对所有轨道，每日计算近实时（NRT）地理定位字段，针对每个1公里MODIS瞬时视场（IFOV）。这些位置及辅助信息对应于地球表面理想1公里带宽内，由10个探测器中心构成的每个IFOV的交汇点。利用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、仪器遥测以及数字高程模型。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1公里样本的陆地/海洋掩膜。产品头部包含附加信息，以实现计算36个MODIS波段中任何波段探测器中心的近似位置。该产品被大量后续的MODIS产品用作输入，尤其是陆地团队生产的产品。该产品的简称是MYD03。
