NSIDC Data Download Script修改为批量下载

缺乏、安全感 2023-01-19 03:07 14阅读 0赞

最近从NSIDC下载数据，想批量下载每一年的1-2月数据

因此对他官方的代码修改如下

只需要修改main方法即可

其实主要是在每个循环中对filename\_filter进行修改

并且每次循环都要将url\_list=None，否则后面就不会重新搜索文件

def main(argv=None):
        global short_name, version, time_start, time_end, bounding_box, \
            polygon, filename_filter, url_list
            
        sy=1979
        ey=2020
        for num in range(sy,ey+1):
            filename_filter = '*'+str(num)+'01*_n.bin'
            print(filename_filter)
            if argv is None:
                argv = sys.argv[1:]
        
            force = False
            quiet = False
            usage = 'usage: nsidc-download_***.py [--help, -h] [--force, -f] [--quiet, -q]'
        
            try:
                opts, args = getopt.getopt(argv, 'hfq', ['help', 'force', 'quiet'])
                for opt, _arg in opts:
                    if opt in ('-f', '--force'):
                        force = True
                    elif opt in ('-q', '--quiet'):
                        quiet = True
                    elif opt in ('-h', '--help'):
                        print(usage)
                        sys.exit(0)
            except getopt.GetoptError as e:
                print(e.args[0])
                print(usage)
                sys.exit(1)
        
            # Supply some default search parameters, just for testing purposes.
            # These are only used if the parameters aren't filled in up above.
            if 'short_name' in short_name:
                short_name = 'ATL06'
                version = '003'
                time_start = '2018-10-14T00:00:00Z'
                time_end = '2021-01-08T21:48:13Z'
                bounding_box = ''
                polygon = ''
                filename_filter = '*ATL06_2020111121*'
                url_list = []
                
            url_list=None
            try:
                if not url_list:
                    url_list = cmr_search(short_name, version, time_start, time_end,
                                          bounding_box=bounding_box, polygon=polygon,
                                          filename_filter=filename_filter, quiet=quiet)
        
                cmr_download(url_list, force=force, quiet=quiet)
            except KeyboardInterrupt:
                quit()
