我已经下载了。 nc 文件（您可以在此处看到它的.csv格式rcp4.5 cloud Cover ------参见Image1 （历史文件和RCP方案 - RCP 4.5、6和8.5 ）。我已经浏览了如何预处理它们的网络（寻找一些教程，更多的直接答案并在线接近），但我仍然不确定。我在qGIS中上传了 .nc 文件（1或2个文件），并使用 gdal2xyz ，发现每个 .nc 文件由几个频段组成（请参阅image2- 
。 ）。
或者，如果没有，可以理解 .nc 文件的组件（至少我要做的 整个正方形网格的平均值或位置我需要的变量，例如：
Precipitation Time
以及 https://cds.climate.copernicus.eu/ 温度，云覆盖物等
，以及我如何预处理？
任何人都可以启发我 .nc 文件
ps。上面的 .csv 文件的图像用于变量：“云封面” （RCP4.5云封面）
I have downloaded .nc files (you can see here the .csv format of it RCP4.5 CLOUD COVER ---see image1
) from https://cds.climate.copernicus.eu/ (both historical files and RCP scenarios --RCP 4.5, 6 AND 8.5). I have browsed the net about how to preprocess them (looked for some tutorials and more direct answers and approach online) but I am still not sure of it. I uploaded the .nc files (1 or 2 files) in QGIS and used gdal2xyz and found out that each .nc file consists of several bands (see image2--
.
I really want to understand .nc file component so I will be able to preprocess it using programming languages like python (maybe)----or if not, be able to understand .nc file's components (at least).
All I want to do is be able to have a time series data of the average of the whole square grid or location I need with variables such as:
Precipitation Time
and other variables available in the https://cds.climate.copernicus.eu/ like temperature, cloud cover etc
Will anyone enlighten me about .nc files and how I can pre-process it?

PS. The image of .csv file above is for variable: "cloud cover"(RCP4.5 CLOUD COVER)
