NSIDC Data Download Script修改为批量下载

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()
