They will automatically be installed with the pip install.</br> </br> <h2>Usage</h2> <h3>Downloading Satellite Imagery from JAXA server</h3></br> Execute ftp_himawari8_hsd</br> Example:</br> <b> > <strong><i> ftp_himawari8_hsd </i></strong> </b> </br> import ftp_himawari8_hsd as ftp hsd=ftp.downloader() hsd.start_date="2021/07/25 00:00" By default it will retrive the last 10 minutes files hsd.end_date="2021/07/25 00:00" hsd.username="foo" Enter your username here hsd.password="bar" Enter your password here hsd.download_path="C:/ftp" Enter your download path here hsd.MAX_WORKERS=8 Enter the number of workers to download here hsd.run() By default it will download files from the last 10 minutes. Necessary inputs are username and password for the function to work You can use ftp.downloader().help() to get this information printed. This will download the full-disk Himawari8 Standard Data as zipped files (*.bz2) and then automatically unzipped (*.DAT).The general HSD file name format is: HS\_aaa\_yyyymmdd\_hhnn\_Bbb\_FLDK\_Rjj\_Skkll.DAT. Letters indicate different information. "HS" means Himawari Standard Data. "aaa" means satellite name and can be H08 (Himawari-8) or H09(Himawati-9). "hhnn" indicates hour and minute (every 10 minute). "bb" indicates band number from 01 to 16. "FLDK" means full-disk. "jj" indicates the spatial resolution in which 05 means 0.5 km, 10 means 1 km and 20 means 2 km."kkll" indicates information on the segment division of HSD. "kk" means segment number from 01 to ll. "ll" means total number of segments ranges between 01 and 99. </br> Examples of download period Date and Time should be in UTC <ol> <li> download for given range of timestamps. Output file timestamps are every 10-minute timestamps from "2021/07/25 00:00" to "2021/07/25 23:50".</li> Enter start datetime yyyy/mm/dd hh:mm: 2021/07/25 00:00 Enter end datetime yyyy/mm/dd hh:mm : 2021/07/25 23:50 <li> download for given time range of current date.
