Hi there, I am Rony. Thanks for making this awesome repository. While exploring the contents of the repository [working-with-sea-ice-conc-data/working-with-sea-ice-conc-data.ipynb], I noticed that the dataset dimensions ygridandxgridare represented in metres/kilometers.

I am particularly interested in learning how to crop/slice the sea ice dataset based on latitude and longitude coordinates. Given that the dataset utilizes ygridand xgrid dimensions, I would like to understand the process of clipping (cropping) the dataset using latitude and longitude coordinates. Alternatively, if possible, I would also like to explore the option of using a shapefile for cropping purposes.

Thank you for your time and assistance.

Rony

Hello Rony, I have uploaded few utility functions to process the sea ice data. here you can crop using a shapefile with geometries from different projection than that of the sea ice data. please take a look at it and see if you can manipulate the python code for your needs.
