Resources

Sharing knowledge is important to us, so we’ve linked some resources to help you learn how we do things in our lab. Feel free to borrow or adapt anything you like.

JupyterLab

JupyterLab is kind of like RStudio. Here is a JupyterLab demo and below is some more information about our lab’s workflow in case you’d like to borrow it:

• How to analyze data with the jupyter/datascience-notebook
• How to customize the jupyter/datascience-notebook container

InGeO

The Integrated Geoscience Observatory (InGeO) is a project supported by the National Science Foundation(NSF). The pilot project was developed under NSF EarthCube grant #1541057 to SRI International. EarthCube aims to improve collaboration between geoscientists, access to scientific data, and reproducibility of scientific results.

DCB and OSB connections: the observation-specific biases (OSB) is a more flexible and general way for code bias representation since it can be converted to the traditional differential code bias (DCB) products directly: (1) Liu, T., & Zhang, B.
