This repository contains analysis code for the manuscript:
Wenegrat, J.O., E. Bonanno, U. Rack, and G. Gebbie, 2022: A century of observed temperature change in the Indian Ocean. Geophysical Research Letters, doi:10.1029/2022GL098217
Raw data (as digitized from the historical cruise reports) can be found in /data/ in pickle format, along with scripts used in loading and processing the historical and modern datasets. Information on which observations are included in the final analysis can be found in /src/loadPickle.py.
A netcdf file containing only the quality controlled historical measurements is also provided in /data/. This is the recommended starting point if you intend to use the historical data in your own separate analysis. Note that this is provided here for convenience, but the version of record can be found at: https://zenodo.org/record/6646659
All code necessary for reproducing figures can be found in the iPython notebooks (/notebooks/).
Note that these notebooks are set up as Google Colaboratory notebooks, but can easily be adapted for use in a standard python environment. To use these in Google Colab, first clone the repository to a google drive account, and then open the notebook using Google Colab. The first code cell of each notebook will configure the necessary environment.
Code for the least-squares analysis of modern minus historical temperature changes can be found at: https://github.com/ggebbie/HistoricalIndianOcean.
A permanent citable doi for this code can be found at:
A citable repository containing just the data in netcdf form can be found at:
