Poseidon-4 Altimetry Level 2 Low Resolution in NTC - Sentinel-6

The product contain the typical altimetry measurements, like the altimeter range, the sea surface height, the wind speed, significant wave height and all required geophysical corrections and related flags derived from LR. Two measurement data files are available (standard and reduced), each with a different number of variables. The standard data file includes 1 Hz and 20 Hz measurements for the Ku- and C-bands as well as geophysical corrections at 1 Hz and some at 20 Hz. The reduced data file contains only 1 Hz measurements for the Ku- and C-bands as well as geophysical corrections at 1 Hz. Processed in NTC (< 60 days).本数据集产品包含典型的卫星测高观测数据，涵盖测高仪测距、海面高度、风速、有效波高，以及所有由LR衍生得到的必要地球物理校正项与相关标记位。本次提供两类测量数据文件，分别为标准文件与精简文件，二者包含的变量数量各不相同。标准数据文件包含Ku波段与C波段的1Hz及20Hz观测数据，同时配有1Hz级别的地球物理校正项，以及部分20Hz级别的校正项。精简数据文件仅包含Ku波段与C波段的1Hz观测数据，以及1Hz级别的地球物理校正项。数据已由NTC完成处理，处理周期小于60天。
