NetCDF (network Common Data Form) 是一种跨平台的用于描述科学数据的格式。
目前可支持的语言版本有(Java, C/C++, Fortran)

3. NetCDF的后缀名
".nc"
（
The recommended extension for netCDF files was changed from ".cdf" to ".nc" in 1994 in order to avoid a clash with the NASA CDF file extension,
and now it also avoids confusion with "Channel Definition Format" files.

4 . NetCDF Data Model
The classic netCDF data model consists of variables, dimensions, and attributes.
Variables- N-dimensional arrays of data. Variables in netCDF files can be one of six types (char, byte, short, int, float, double).
Dimensions- describe the axes(轴) of the data arrays. A dimension has a name and a length. An unlimited dimension has a length that can be expanded at any time, as more data are written to it. NetCDF files can contain at most one unlimited dimension.
Attributes- annotate(注释) variables or files with small notes or supplementary metadata. Attributes are always scalar values or 1D arrays, which can be associated with either a variable or the file as a whole. Although there is no enforced limit, the user is expected to keep attributes small.
5. NetCDF存储哪些数据？
坐标轴信息: 纬度, 经度, vertical level, 时间
物理信息: 气压, 温度
