Time series of Agulhas leakage from satellite altimetry. Update of Le Bars et al. 2014.

Agulhas leakage time series updated from Le Bars et al. 2014 and Kelly et al. 2016.

Final results are stored in:

Trp_track_twb122_barot30W.nc,Trp_track_twb20_barot30W.nc and Trp_track_twb198_barot30W.nc

An example of analysis and comparison with older time series is in the Python 3.9 Jupyter notebook:

AnalyseOutputs.ipynb (AnalyseOutputs.html to simply visualise)

The code and intermediate results are also provided. See README.txt for instructions on how to use it. It was written in 2013 with the NCAR Command Language and Python 2.? but it can still run now with later version of NCL and with Python 2.7.
