This toolbox contains a standard set of MATLAB functions for analyzing and displaying climate data. The functions are computationally efficient, easy to use, and come with many tutorials that describe not only how to use CDT functions, but also offer guidance on how to interpret the results in the context of Earth science processes.

Thank you for the very helpfull toolbox!!!!!!!.
An example for complex EOF or something similar for current U and V EOF would be helpfull,
Sincerely

Can I use this eof function for doing Complex EOF analysis (for wind vector) by just providing the input in complex form (U +iV).
My interest is in doing eof analysis for wind vector.

Thanks so much for this toolbox

@S: Thanks for the note! The globefill function solves the issue of transparent globes. https://www.chadagreene.com/CDT/globefill_documentation.html

Hi Chad,
Thanks for this helpful toolbox
I think the globeborders function is not working as intended, the surface seems to be transparent and shows the borders on the otherside of the hemisphere as well.

How does the EOF program handle cyclic data at the poles? There is a large value discontinuity at the Prime Meridian, even when addressing the boundary condition prior to using the function, and the equal-area gridding used with datasets like CFSR, NCEP-NCAR, etc means the concentraion of data increaes with latitude.

Thank you so much Chad. I managed to get the updated version of trend fuction

@Franck: That should work fine as long as the input t is a 1D array of length 288. If you type

cdt deseason

do you have any trouble running the examples?

Feel free to send me a personal email if you have a simple example I can run to recreate the problem.

@chad: this is the dimension of slp 33x17x288 (lon,lat,time)

Chad Greene

@Franck: What are the dimensions of the slp grid, and what are the dimensions of the time array?

Nice Job/toolbox Chad.
I would like to know how can I use deseason to remove seasonal cycles from the 3d grid slp(lon,lat,time) dataset.
I have tried to follow up your instruction but didn't succeed "Error: length of t must match dimensions of
A".
