Read netCDF files and display variable information

Loads netCDF files and displays info about variables. Tested for ERA and NCEP/NCAR reanalysis data.

Description

This script loads netCDF files into MATLAB and displays info about the dimensions and variables.

The code should at least work on ERA-40, ERA-interim and NCEP/NCAR reanalysis data.

I wrote the script since I can't find a function in the built-in set of netCDF functions included in MATLAB that displays all header info of the file, equivalent to the old 'ncdump' function.

• MATLAB release: MATLAB 7.10 (R2010a)

Roberta,

There is a link to the upper right of the web page "CS_read_netCDF.m". If you left click on the link you will see the code and you can copy/paste. You can also right click and choose "save link as" and save the file to your computer. Hope this helps.

This file does not exist... How / where can I find this script? Thank you... I work with NCEP/NCAR and I really need this.

Thanks, this was very close to what I was looking for and worked as an example of using the low level NetCDF routines.

I wanted to pass the data back to a calling routine as a structure, and also wanted to remove the singleton dimensions, so I updated the getVar call to:
eval(['dstruct.' varname '= double(squeeze(netcdf.getVar(ncid,i)));']) ;

Since I also wanted to load the attributes into another structure, I needed to add some steps to handle attribute names that are not legal field names, converting spaces etc to underscores; also the assign statements for character attributes needed to be modified for that.

An excellent example file for the Matlab help would be a routine that loads a NetCDF file, modifies some fields, and writes out a new NetCDF. That would cover all the bases, I think. In the absence of that, this was a big help - thanks!
