Hello. I am new to MATLAB. I am interested in creating time series plot (like the attached figure) for chl a of a large area from six netcdf files. Each netcdf file corresponding a year. can anyone help me with the procedure or the MATLAB code to excute this task, please???

here is the link for the six netcdf files (https://drive.google.com/drive/folders/1iGMwaYh-rqUmZ8uC6mgfKk6gInnsubqN).

thank you in advanced.

Hi!

I resolved this issue by myself. I used Climate Data Operator (CDO), which is very handy in terms of handling netcdf data. After organizing the data through CDO, I used MATLAB for ploting.

Thank you.

Read each netCDF file. Concatenate the arrays. Plot the concatenated arrays.

Mir, I'm not very familiar with MATLAB's netCDF features, but there are ways to read the files and you should read the doc about that. Once you've gotten the data into MATLAB, I'd recommend converting to timetables with datetime row times, and then probably concatenating those, and plotting against time. Amybe use stackedplot if you have multiple variables. Don't know what you data look like, so can't really help more than that.
