平均多个.nc文件- Linux上的NCO操作符

Question

我有一个包含60+ netCDF (*.nc)文件的文件夹。我需要找出所有60+数据文件的平均值，但我在终端中遇到了错误。

因此，我只需要知道如何计算所有60+文件的平均值并将结果保存在output.nc文件中(我知道如何一次处理2到3个文件，但有没有一种方法可以处理所有的60+文件？)

这是我尝试过的：'ncra data_ncfiles/* dataaverage.nc --> *应该告诉Linux文件夹中所有60个文件的平均值。

我得到的错误是：ncra: ERROR nco_sng_sntz() reports character '' from unsanitized user-input string "CbPM_ncfiles/" is not on whitelist of acceptable characters. For security purposes NCO restricts the set of characters appearing in user input, including filenames, to: "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890_-.@ :%/". NB: This restriction was first imposed in NCO 4.7.3 (February, 2018), and may cause breakage of older workflows. Please contact NCO if you have a real-world use-case that shows why the character '*' should be white-listed. HINT: Re-try command after replacing transgressing characters with innocuous characters.

我也试过不打星号，但没有用。

更新:我又试了一次：

ncra data_ncfiles/* dataaverage.nc

并得到了这个错误：

ncra: ERROR no variables fit criteria for processing ncra: HINT Extraction list must contain at least one record variable that is not NC_CHAR or NC_STRING. A record variable is a variable defined with a record dimension. Often the record dimension, aka unlimited dimension, refers to time. To change an existing dimension from a fixed to a record dimensions see http://nco.sf.net/nco.html#mk_rec_dmn or to add a new record dimension to all variables see http://nco.sf.net/nco.html#ncecat_rnm

Answer 1

此命令

ncra data_ncfiles/* dataaverage.nc

依赖于shell-globbing来扩展文件名列表。如果ls data_ncfiles/*提供了来自同一目录的预期文件列表，它将会工作。你的帖子不清楚，但你可能已经通过使用引号关闭了globbing。

下一个错误ERROR no variables fit criteria for processing通常发生在您的输入缺少记录维度时。这个可怕的错误恰好指向了如何解决该问题的说明。按照这些说明进行操作。
