Scripts for the article "Phytoplankton Chlorophyll trends in the Arctic (1998-2022) at the local, regional, and pan-Arctic scales".

These MatLab files contain all the data processing and analysis for the article. They also reproducde all the figures.

Everything can be done by running the file "Wrapper_Arctic_phyto.m".

The satellite data needs to be downloaded beforehand and paths in the "Wrapper_Arctic_phyto.m" need to be adapted accordingly.
