Welcome to the Climate Data Toolbox for Matlab! Here are some tips on getting started with CDT:


CDT Contents

For a complete list of CDT functions, datasets, and tutorials, check out the CDT Contents page.

Downloading CDT

The best and most up-to-date version of CDT can always be found on GitHub or you can install it directly through the Add-Ons menu. That looks like this in the HOME menu:

Click Get Add-Ons, look up Climate Data Toolbox, and follow the prompts to download and install CDT automatically.

Other options You can get a usually-out-of-date latest "Release" of CDT here (about 100 MB) and just double-click on the file to install it:

Just double-click on that file and when the menu pops up, click Install. Installation should take less than a second.

2. Alternatively, if you haven't already downloaded the mltbx file, you can get it via the Add-On button from directly within Matlab.

Accessing Help

Need help? Just type


to access TMD documentation. For help with specific functions, type cdt followed by the function name. For example,

cdt eof

to access help for the eof function.
