HMI AFT Baseline Maps

This version of the AFT HMI Baseline was created by assimilating hourly HMI.M_720s magnetograms (http://jsoc.stanford.edu/HMI/Magnetograms.html) beginning May 1st. AFT maps for this series are output at a cadence of 6 hours per day (at 0,6, and 12, 18 hours), however only 1 map per day is provided here. The data for each year are saved into a separate directory. Each file is a 1024x512 array in longitude and latitude. In the meantime, if you have any questions or if you need a specialized AFT series (e.g., different cadence) please feel free to reach out to us. The data loader and reader can be accessed via public repo https://github.com/bibhuraushan/aftpy. Use pip to install the package "pip install aftpy".

本版AFT HMI基准数据集（AFT HMI Baseline）通过同化自5月1日起的逐小时HMI.M_720s磁图（magnetograms，http://jsoc.stanford.edu/HMI/Magnetograms.html）构建而成。该序列的AFT图以每日6小时间隔的频率输出（即每日0、6、12、18时生成），但本数据集仅提供每日1张AFT图。每年的数据均存储于独立目录中。每个文件为以日面经度与纬度为维度的1024×512数组。与此同时，若您有任何疑问，或需要定制化的AFT序列（例如不同采样频率的序列），欢迎随时与我们联系。数据集的加载与读取工具可通过公开代码仓库https://github.com/bibhuraushan/aftpy获取，可通过pip工具安装该工具包："pip install aftpy"。
