ncagg 0.8.10

tl；dr

使用pip安装实用程序：

pip install ncagg

在命令行上，使用 ncagg ：

Usage: ncagg [OPTIONS] DST [SRC]...

Options:
  -v, --version                   Show the version and exit.
  --generate_template PATH        Print the default template generated for
                                  PATH and exit.
  -u TEXT                         Give an Unlimited Dimension Configuration as
                                  udim:ivar[:hz[:hz]]
  -b TEXT                         If -u given, specify bounds for ivar as
                                  min:max or Tstart[:[T]stop]. min and max are
                                  numerical, otherwise T indicates start and
                                  stop are times.start and stop are of the
                                  form YYYY[MM[DD[HH[MM]]]] and of stop is
                                  omitted,it will be inferred to be the least
                                  significantly specified date + 1.
  -l [DEBUG|INFO|WARNING|ERROR|CRITICAL]
                                  log level
  -t FILENAME                     Specify a configuration template
  --help                          Show this message and exit.

注意：

• dst是netcdf输出的文件名，不应该是 存在，或将被覆盖。
• src是要聚合的输入netcdf文件的列表，可以传递给 命令行或管道发送到NCAGG。
• -你应该指定一个不受限制的维度配置。见下文 详细信息。
• 一天花几十分钟是正常的，进度条会 指示剩余时间。
• 对于输出的细粒度控制，请指定配置 模板（-t）。详情见下文。

示例：

#     explicitly list files to aggregate
ncagg output_filename.nc file_0.nc file_02.nc #...

#     aggregate by globbing all files in some directory
ncagg output_filename.nc path_to_files/*.nc

#     sort the unlimited dimension record_number, according to the variable time
ncagg -u record_number:time output_filename.nc path_to_files/*.nc

#     sort the unlimited dimension record_number, according to the variable time, and insert
#     or remove fill values to ensure time occurrs at 10hz.
ncagg -u record_number:time:10 output_filename.nc path_to_files/*.nc

#     only include time values between 2017-06-01 to 2017-06-02 (bounds), including
#     sorting and filling, as above
ncagg -u record_number:time:10 -b T20170601:T20170602 output_filename.nc path_to_files/*.nc
#     or equivalently, if only one bound is specified, the end is inferred to be most significant + 1
ncagg -u record_number:time:10 -b T20170601 output_filename.nc path_to_files/*.nc

#     aggregate more files than fit on the command line... (in case of: Argument list too long)
find /path/to/files -type f -name "*.nc" | ncagg output.nc
