Jupyter book tutorials demonstrating xarray-based workflows for cloud-hosted remote sensing data

Recent advances in satellite imagery availability, cloud-computing resources and open-source software represent exciting developments in earth science and climate research. Access to computing resources and storage are significant bottlenecks and barriers to participation that hinder efforts to undo historical legacies of exclusion in the sciences. Transitioning to cloud-based workflows has the potential to drastically increase efficiency and broaden scientific participation, two important objectives on the path to understanding and preparing mitigation strategies for a changing climate.

With evolving computational tools comes the associated need for detailed, accessible documentation and educational resources to increase usership of these tools and datasets. This work presents Jupyter Book tutorials focusing on datasets relevant to cryospheric research: Inter-Mission Time Series of Land Ice Velocity and Elevation (ITS_LIVE) glacier surface velocity and Sentinel-1 radiometric terrain-corrected (RTC) backscatter data. The tutorials demonstrate accessing and interacting with cloud-hosted remote sensing datasets on platforms such as Amazon Web Services (AWS) and Microsoft Planetary Computer (PC) using the open-source Python package xarray. We focus on complex, novel, real-world datasets that carry considerable scientific value. The tutorials were developed with an emphasis on accessible, explanatory text that includes solutions to commonly-encountered errors, step-by-step descriptions of xarray functionality, and ways to incorporate xarray tools to improve common scientific pipelines. Scaling educational resources related to remote sensing datasets, cloud-computing resources and scientific data analysis is critical in order to leverage the potential of these resources and realize their benefit. This work provides broadly applicable, accessible examples and establishes  a framework through which future examples may be developed
