MODISTerra星L1B数据产品-MOD021KM

产品介绍：MODIS-L1B是MODIS系列数据产品中的一种（与已经发布的MODIS-land产品并列），即经过仪器标定的Modis数据产品，产品编号为 MOD02/MYD02。包括3 个科学数据集（QKM, HKM, 1KM）。L1B数据需要与经纬度坐标数据（MOD/MYD03）配合使用。其中：
MOD/MYD02QKM校正过的的对地观测数据，分辨率为分辨率为250米，波段为1, 2；MOD/MYD 02HKM包括被聚集的250米分辨率以500米分辨率显示的波段，波段为： 3, 4, 5, 6, 7；
MOD/MYD 021KM 包括被聚集的250米和500米分辨率以1公里分辨率显示的波段，波段为：8-19, 26, 20-25, 27-36；MOD/MYD03 为1KM经纬度坐标数据，分辨率为1000米。
组织方式：Swath，按影像获取时间对数据进行分块，每个数据块包含大约5分钟的MODIS数据。

Product Introduction: MODIS-L1B is one of the MODIS series data products (alongside the already released MODIS-land products), which refers to instrument-calibrated MODIS data products with product identifiers MOD02/MYD02. It includes three scientific datasets (QKM, HKM, 1KM). L1B data needs to be used in conjunction with latitude and longitude coordinate data (MOD/MYD03). Among them:
MOD/MYD02QKM is calibrated Earth observation data with a resolution of 250 meters, covering bands 1 and 2; MOD/MYD02HKM includes bands aggregated from 250-meter resolution to 500-meter resolution, covering bands 3,4,5,6,7;
MOD/MYD021KM includes bands aggregated from 250-meter and 500-meter resolutions to 1-kilometer resolution, covering bands 8-19,26,20-25,27-36; MOD/MYD03 is 1KM latitude and longitude coordinate data with a resolution of 1000 meters.
Organization: Swath-based, data is chunked by image acquisition time, with each chunk containing approximately 5 minutes of MODIS data.
